Gardeners Worst Nightmares: 28 Perennials You’ll Regret Planting

Perennial plants are a good investment.  Plant once and have flowers that bloom for years.  However, some plants that seem innocent enough literally take over the garden and quickly spiral out of control.  Others bloom for such a short time that they don’t seem worth the trouble.  Here’s a list of 28 perennials I’d rather not see in my next garden.

Disclaimer: This post contains plants that are problematic in USDA hardiness zones 2 and 3.  Some of these plants may not be problematic in your area.  If you have difficult growing conditions, you’ll want to put these plants on your next shopping list.  🙂 

Disclaimer #2: Just because your favourite plant is on this list doesn’t mean it is “bad” or you shouldn’t plant it. This list is intended for brand new gardeners who think these plants are low maintenance, then aren’t able to keep up with them when they get out of hand. I just wanted to spare them some heartache until they get better at gardening and are able to keep up with any more aggressive plants.

The Invaders

1. Lily of the Valley

Hated by experienced gardeners everywhere, it’s best to confine this one to a pot if you can.

2. Anemone

Plant only if you like running around in circles trying to contain it.

3. Yarrow

I love yarrow, especially for making floral arrangements all summer long.  However, it will spread to your lawn and is very difficult to get out.

4. Ferns

If you’ve read this blog any amount of time, you know I really dislike ferns.  Last year I removed at least 100 from our yard, and this year I’m already at 22.  (I’ve only cleaned out the area that I worked on last year. . . grr.)  They look beautiful, but if you want to remove them it takes a lot of muscle power.  I recommend using a hand-held garden tiller like this one.

Update: I counted and kept track this season and I pulled out 218.  Yes, you read that correctly. . .218 ferns.

Curious about what’s in my backyard?  Check out what we started with and this years progress on our urban garden.

5. Lady Bells/Bellflower/Campanula

These are EVERYWHERE in my overgrown backyard and they are driving me crazy.  However, I’ve had decent luck keeping them under control since I dug up most of them last year.  This tied for most hated perennial in my local gardening Facebook group.

6. Daisies

Just don’t.  Yes, they are pretty, but they’ll be out of control within 3 years.

7. Chinese Lanterns

I LOVE my Chinese lanterns, but they are slowly taking over my lawn.  The roots travel just below the surface, so chemicals are the only way to get them under control.

8. Lemon Mint (Beebalm)

A beautiful herb that is so aggressive it will grow in gravel.  Enough said.

9. Goats Beard

Any plant that resembles a dandelion in full seed is probably not a good idea.

10. Persian Coneflower

Self seeding and fast-spreading.  Unless you have lots of goldfinches that will eat the seeds and keep them under control, don’t plant it.  See more photos at Dave’s Garden.

11. Soapwort

Very useful as a natural cleaner, but can run wild if it has ideal growing conditions.  Learn more about soapwort at The Herb Gardener.

12. Veronicas

When a plant’s other name is Speed Well, you know it’s going to overtake your garden in short order.

Ground Cover Gone Wild

13. Lamium

Another great solution for ground cover in a shaded area. . . until it takes over in 5 years.

14. Clover

Unless you want it as your lawn or have a horse to feed, don’t plant it.

15. Snow on the Mountain/ Bishop’s Goutweed

While it works great for ground cover in a shaded area, you will never, ever get rid of it.  In my poll on my local Facebook Gardening group, this tied bellflowers as the most regretted plant.

Keep it in a Container

16. Mint

You know that friend who is always trying to pawn off mint to you?  This is why.

Does a plant have mint in it’s name?  Chances are it’s super invasive.  Catmint and Lemon mint, I’m looking at you.

17. Shamrocks

Shamrocks are beautiful indoor container plants, but become an invasive headache if planted outdoors.

18. Oriental Limelight

Cut back aggressively in June and DO NOT plant anywhere outside of a container.  For more information, check out perennials.com.

Too-Short-Blooming-for-the-Effort-Perennials

19. Irises

Irises are so gorgeous, but it seems like they last for 2 days and then they’re done.  They can also get out of control if not divided regularly.

20. Day Lilies

There are so many beautiful day lilies, but the variety I’ve grown seems to bloom for less than a week and take up a lot of space.  If you plant the common orange one, it will take over your pretty specialty hybrid ones over the years.  And that would be tragic!

Difficult in Saskatchewan

21. Any plant labeled Zone 4A or Higher

It doesn’t matter if you’re going to put it in a south facing spot right against the house. . . it will die.  Unless you live in the southern-most areas of the province you can maybe scrape by if you mulch it well.  Enjoy your zone 4A-ish privilege.  Nope. . .not bitter at all. . .

22. Roses

While not impossible to grow, especially if you choose a variety bred for the prairies, it is best left to more experienced gardeners.

23. Dahlias, Calla Lilies, or any other plant that you have to winter indoors

Unless you like that sort of thing.  Carry on.

Update: Since I first wrote this post I have come to love this sort of thing. But I don’t recommend it if you’re brand new to gardening, as you likely will not remember to bring them in for the winter.

The Impossible to Kill

24. Rhubarb

When I was young my Dad dug out our rhubarb plant at least a foot and half down and sprayed it with round-up.  It still came back.  I personally like having a rhubarb plant, but any more than one is excessive.

25. Raspberries

While the fruit is delicious, be prepared for your canes to spring up in unexpected places.

26. Snow on the Mountain/ Bishop’s Goutweed

It’s so hated it deserves to be listed under two categories.

27. Hollyhock

Hollyhocks only live for two or three years but are masters of reseeding themselves.

28. Comfry

While super useful as a medicinal plant, comfry plants can take DECADES before they start to decline.  Learn more about it at The Spruce.

29. Perennial Bachelor’s Button

Another prolific self-seeder.  Save yourself the headache and plant the annual version from seed instead.

30. Virgina Creeper

The good news: it will grow in practically any light or soil condition.  The bad news: it will grow in practically any light or soil condition.

31. Tansy

The tansy weed can produce up to 150 000 seeds a plant that remain viable for up to 15 years. (Source: bcinvasives.ca)

P.S. Wondering why there’s 31 perennials when the title is 28? I’ve since updated this post from my original publishing, and I counted one perennial twice because it ended up under 2 categories.

One mans weed is another man’s favourite flower.  If you really love any of these perennials, please don’t let this list stop you from planting them.  You can always just embrace the overgrowth.

Want to know what you should plant instead?  Here’s 53 Perennials you have to have.

A super special thank you to the gardeners in the Gardening in Saskatchewan Facebook Group.  Your generosity is amazing and this post would not have been possible without you!

  1. Thank you for the zone info!!! I am trying to get an idea of wtf we are!!!!! No ones else seems to give such a straight answer

    • Most of Saskatchewan is zone 3A or 3B. The southernmost places are 4A, and anywhere from Prince Albert and north is 2B.

      • Kristen, thank you for the info about what not to plant. I would like to add a couple of periennels to your list. One is "Primrose". It has dainty looking pink flowers, about medium size. I fell in love with it at the Garden Center. I only planted 2 of them in small containers in my garden the summer of 2016. It wasn't long & they were everywhere. This Spring they overtook my entire garden. The more I pull them up, the faster they spread. They only bloom in the cooler weather, when it gets warmer in summer, they stop blooming but their stems & leaves remain. A true Nightmare! The second one is Ivy. If you plant Ivy near your house, it climbs all over your house. It attaches itself to your house & when you pull it off, it takes the house paint with it. I had to re-paint the side of my house where it was growing. What a mistake planting Ivy!
        Reply

          • another invasive plant is the morning glory! I can't believe they actually sell seeds!! Horrible stuff

          • F you live in the southern tier of the US, don’t plant Asian ivy unless you want to spend a lot of time sculpturing it along a walk. It’s highly invasive and you literally have to burn it out to get rid of it.

        • my bane of existence for the past 9 years have been the groundcovers that the people that had the house Before us planted. (What possessed them, I don't know! Is there a garden lucifer gnome???) They planted vinca minor, st.john's wort and then vinca major!!! Triple threat! The front yard is an eighth of an acre, not huge but more than big enough! Been trying to pull them up by roots...took 4 years and then it rained/snowed so much this past year all the area i had cleared (about 3/4 of the front yard) grew back! Finally said to H*** with it and grabbed the heavy weed-eater. I guess I will lay down a good soak of vinegar (the ground is already acidic, being in a pine forest) and then a thick layer of newspapers and can get pinewood chips from the fire dept from their free chipper program. Will spread them all over to cover the newspaper. Maybe then next year I can start uncovering bit by bit parts to work a garden in to of my own...either that or start doing small groupings of seating and container gardens....... Just warning about the vincas and the st. johns wort...
          Reply

          • Hopefully you have luck with that! Most of the ground covers will survive that first winter under heavy mulch...just went through this process--and its a chore for sure!

        • I don't actually hate most perennials, I'm just not as patient or willing to pick tons of stray plants at this stage in my life. I also have a yard that is overrun with ferns, lady of the valley and bellflower that I have been picking non-stop for three years, so it does make me a bit more salty. If you love it, you should plant it ;-)

          • Thanks for a great article. I live in Nebraska (zone 5). 85 year-old house. 3 lots. Soil not great. Lots of sun. Some heavy shade. I want invasive plants in part of this, to replace weeds where I don't want grass. (I'm 73, so crazy, huh?) However, this year I did have black-eyed Susans take over the area south of my house where we cut down trees last fall. Not fun getting it back so I can plant sun-loving plants to replace the shade-lovers that I moved. But, thanks to you, I know more about what to plant where I want lots of color and what to plant in containers.

          • I too love black eyed susans, but found after years of trying to tame them that they simply have to have their own self contained garden. What a beautiful presentation. My biggest mistake was planting "obedient", a very pretty plant, named because once cut, you can bend the stems as you wish in a vase arrangement. BUT, it reseeds everywhere! At first I was delighted, and now am in my third year picking each stem out. I wish I had a field to spread them around as a beautiful wild flower (pink and white varieties).

          • Funny how some of your choices I also have trouble with and some I have trouble trying to make spread! I love my daisies and tho they do spread like crazy, I just thin them out every fall or Spring. They pull out fairly easily. Gooseneck, spiderwort and those orange day lilies are relentless as is malva. Everyone has their opinion on what they like, but I would have appreciated the warning on some of these before I planted them. Morning glories are just plain evil. They came to my yard uninvited.

        • I know...right? I cannot believe the advice given in this article....absurd!!!! Day Lillies, Iris, Roses, lily of the valley, veronica, Hollyhocks????? Unfreakingbelievable!!! How can you have a flower garden without these staples? You have totally blown this flower gardeners mind!!! I have no problems with any of these....
          Reply

          • Cindy, I agree with you 100%. Most of the “hated” perennials in this article are staples in my zone 7 flower gardens. Different strokes for different folks I guess, but I sure would hate for a new gardener to read this and dismiss these amazing flowers without further research. I love sharing bouquets of daisies, irises, roses and day lilies with friends, and some of the plants such as clover and dandelion are pollinators for bees. Oh, and the butterflies that feed on my morning glories that climb my chicken pen are such a pleasure to watch. Actually, butterflies are attracted to any flower with nectar.

          • I agree with Cindy and Debbie. Iris, Roses, Daylilies, Hollyhocks? They are my favorites. Zone 7B people pull into our drive all the time to tell me how beautiful my Gardens are.

      • I planted a flower that looks like a daylily but the purple blooms bloom only in the mornings and I planted it a few years ago now it's has taken over my whole yard
        Reply

        • The "wild" type of daylily, the Orange one, is invasive and will take over the hybrid ones until they are all Orange. I live in zones 8 and 9 and have had terrible problems with purslane and morning glory.
          Reply

          • I don't think these "wild" orange daylilies are daylilies at all. You are so right, they fill in nicely and then take over, so plant carefully. I find them delightful and so easy to split if they get out of hand. In upstate NY, we call them orange "ditch lilies" because you find them along the roadside everywhere. haha.

    • To each their own ~ I saw maybe 6 i'd be mad at myself for planting. I have about 10 listed and do not regret having any of them. Perhaps it's the size of the garden (s) that could be a problem. I'm very fortunate to have 4 acres. I see another 10 i'd love to have..invasive or not ! Beauty in the eyes of the beholder. I love attracting butterflies, birds...especially hummingbirds and have read many of these perennials attract all. Thanks for the article anyway !

        • We had cats, and I planted one catmint plants. All of my kitties have since passed away, but I’m STILL digging out catmint that totally took over 2 of my gardens! UGH!
          Reply

          • OH YES!!!!! I tried for several years to get it established before the cats pulled it up and rolled in it. Then it got a head start and now is all over, BUT I tolerate it because when the cats role around in it they do not get fleas and ticks. So far no one has mentioned Ajuga. I have been fighting it for many years now.

          • Besides bindweed, I have a problem with the neighbors five cats using my garden as their bathroom. My other neighbor has a walnut tree and i now have walnut seedlings popping up everywhere. I have so many of these invasive plants and it's a full time job keeping up with them. ie. lily of the valley, mint, oregano, vinca major, raspberries, holllyhocks. I believe the bindweed came when we got free soil from the city for our raised garden bed.

        • When I still lived in a house I read somewhere to plant mint in a pot and sink it in tho soil. Noooooo it’s jumps out anyway! . While mint invading your garden is a nuisance, it’s is not so terrible if it invades your lawn unless you’re married to the idea of a one-species lawn(not the most environmentally-friendly idea). Mowed mint (camomile too) smells lovely.
          Reply

          • They plant camomile in the lawns of Buckingham Palace for the scent. I have mint in parts of my lawn and quite frankly, I love it.😉

        • It is. It's for people who want to get started in gardening but might not realize how much work actually goes into it or what plants might end up being invasive if they don't look after them every year.
          Reply

          • Beginner gardener here, you hit the target audience! I bought my first home and planted my first garden this summer. I really appreciate this helpful article! I planted peppermint and spearmint in a raised border bed on a rocky slope. It is erosion prone and hard to mow, consequently the rest of the bed is filled with hardy plants like coneflower, coreopsis, sage, milkweed. They've only had a few months to get established so if I made a rookie mistake planting mint I'd like to nip it in the bud ;) Will the rocky soil and aggressive neighboring plants help keep mint in check or would you suggest I dig the mint up now before spring comes?

          • What part of the world are you in? Do you know what kind of soil you have? (Where I'm from tends to have really good soil, so some of the plants listed here aren't as big of nuisances in other areas.) It sounds like the mint is in a confined area, so it should be okay. However, if those other plants aren't super established, it might take over. If you're really worried, take it out this spring and move it to a pot. You can even dig that pot into the ground if you'd really like to keep it in the one area.

        • Besides Virginia Creeper, I cannot think of a single one of these other ones I would give up in my gardens....so not understand this article at all!!!
          Reply

      • I agree....I was shocked when I read this article!!! Most of these plants are fantastic and I have never had a problem with any of the besides Vinca Major that the previous owner planted....the worst one is Autumn clematis and even then I let it grow certain places....but it will take over a garden even tho it is beautiful in the fall and smells delightful....just don't do it!!! and Virginia Creeper is a weed...and very invasive but Holly Hocks...day lillies.....veronica, lily of the valley, roses ...daisies????? I would plant them in a heartbeat!!!
        Reply

      • I'm with you on this one. My mint is excessive, but I drink lemon mint water daily in summer. I personally love a wild garden that produces all summer long. Dies it take a lot of work, yes, but it gives so much back to the pollinators, birds, and us. If you could train a groundhogs to eat what you don't want, now that I'm all for!
        Reply

    • This is the most crazy info I've ever read. Most of these plants are plants I love and have in my yard. You have to know how to manage them / not eradicate them! How sad. You probably hate kittens, too.
      Reply

      • Just the little ones. . . kidding!!! It's true, if you know how to manage them, most of these plants don't have to be a problem. It also depends on your soil conditions and growing zone. This article was originally written with plants that are problematic in zone 3 in mind. Since then I've learned a lot from everyones comments.
        Reply

        • I agree on every one, having had them all out of control one time or another. Wish I'd known this info as a young gardener 30 years ago. Thank you!
          Reply

          • I also agree, I have had most of them except the hated lily,of the valley which is one,of the worst weeds ever. Some of these cannot be controlled unless you use,something like roundup on them not a good choice but sometimes necessary. We tried to get rid of virginia creeper and after digging about 10 feet down and still finding viable roots we did resort to round up and it took 2 years of roundup usage to finally destroy them. Any new gardener that plants any of these plants will soon hate gardening. Only a fool or unlearned person would purposely plant them.

      • Why so many negative comments on this post? Snarky negative comments..... here’s a tip... READ the entire article, if you do you read her explanation as to WHY she feels that way... she also states “IF HOU LIVE THEM, PLANT THEM”.... people can be so nasty these days... I read as many negative Nancy’s as I could..... then I had to respond.... enjoy your plants.... I love the information... I’m not one for chasing plants all over the yard.... I moved into a home over a year ago... whoever was here before me stuck plants in any free space they could find... and a lot of them spread..... so, no it hasn’t been fun for someone whose not a Sweet Young thing, who has a bad back and other pain issues to try to get my yard under control.... garden on folks!!!!!

    • But ferns reproduce by spores, and those carry easily on the wind. Better in containers if spreading is a concern, but maybe best in caontainera away from the ground/on a large patio?
      Reply

      • Ferns can also spread by their roots. Hay scented fern roots form mats several inches thick and it's awful to remove. Keep in mind that not ALL ferns are invasive! Some behave very nicely. Please do research on what works on your area. Ferns are beautiful, and many are non-invasive.
        Reply

        • Yes, I agree. First it depends on where you live and your garden knowledge. And yes your ability to manage any particular one. I would never plant lamium as I've had it take over areas I've not yet gotten to. What you show as 'fern' is I believe bracken, not a fern at all. Very annoying as it runs and pops up everywhere. All you can do is keep pulling it up, gatting as much of the runners as you can. Ferns, on the other hand, spread via spores but they do so most sparingly. I have many and wish they would more easily self propogate. I live in a 7B-8A climate so pretty perfect if they were going to easily propigate.

          • Thanks for the encouragement! I think there are some ferns that don't get out of control, but whatever is in my backyard is an absolute nightmare. If you do buy a fern, buy it from an actual garden centre and ask the staff for advice on picking one.

  6. Great tips! I am a beginner at gardening and just planted a bunch of flowers in my front flower beds. I'm pretty sure I didn't plant anything from your list!

        • Mom planted ivy in the woods to avoid dealing with leaf raking on that acre. 50 years later it is the ivy that ate the forest. Was 25 feet up the trees. Goats brought in did not control it. Finally a winter was bad enuf the deer dug thru the snow and dined, also ate 8 ft up the trees. Next spring it was sort of trimmed back. 17 yr old boys digging plus a backhoe when we dug the septic mostly got the last of it. She planted 10 shoots. 50 years later it was an acre! Worst part about ivy is that it hibernates any stray poison ivy so getting it under control is a nightmare. Skip the ivy.

    • I did the same thing!! I still have no idea what all is in my garden. The whole front yard which really isn't that big was covered in various plants. I had them all dug up except for under the front window and out grass in. I like it and I've received compliments from a few of my neighbors!

    • Lucky you. I am trying to keep careful notes for whomever gets my house one day. I've practically killed myself in this yard and I want someone to continue to love it. As it is, I live in good old HOT HOT HOT Texas and would kill, well, not really, to grow some of these. Most of them turn up their toes as soon as summer hits here. My sweet little primrose took one whiff of Texas in the summer and turned to dust. My raspberries struggle and haven't even seen one berry this year. It must be wonderful to garden where your plants don't cook. While my zucchini has leaves that would put the biggest elephant ears to shame, there is no fruit this year. I am so sad. The only thing really thriving is cannas....even the ferns I planted refused to grow. In my next life I am going to live along the nw Pacific Coast. What is a bane to you people would be a glorious here. I am envious.

  8. I had to laugh when I passed by the mint photo! I planted it and soon realized how 'happy' aka invasive it is! The next year dug it up and buried a pot below ground and replanted it in it. I love having fresh mint, so that was my easy solution!
    Reply

  9. Mint, oh my god the mint! I didn't realize it was hardy when I emptied my herb container in the compost pile at the end of the season. Boy do I regret that life choice! It has taken on it's own zip code in my backyard and it just keeps growing. In fact the worse I treat it the more it thrives! I warn COMPLETE strangers about mint when they are looking at them at the plant stores! LOL!

      • I can’t believe orange trumpet vine Campsis Radicans isn’t on this list. It is the Satan of the plant world. It travels underground and pops up in every garden bed, in my hedges, under my pool, up against the rails of fencing, in my lawn. In my butterfly bushes, my lilies. I’ve read so many internet message boards trying to find a way to kill it. You can’t pull it up, it’s too deep. Digging down and putting weed killer on roots doesn’t work. From what I’ve read, only digging very deeply, cutting it and pouring boiling water on it works. The problem is I have it everywhere and how can I keep water at boiling temperature? And it’s in my garden beds so it would have to all be killed in the spring, when it’s pouring outside. If you leave any of it, it comes back worse. I have arthritis. I know I can’t dig that much that fast and my landscaper refuses to do it. I can’t blame him - who wants to accidentally scald themselves? I bought it at Lowe’s about 20 years ago. It was sold under the Martha Stewart brand back when she branded everything in the world. I hate her for it. This plant should be banned from cultivation everywhere.

  10. Oh Comfry! My mil & I spent years digging it up & spraying layers of roundup everywhere. Every single year we've continued to do this. Last year we took the last few bits, soaked everything in vinager & laid down thick pieces of cardboard, rug and plywood with rocks on top. Condo board gave me warnings even though I explained that I was following the previous rules to get rid of comfrey. So we put pretty flowering baskets on top & decorative rock ;). The entire 3 months of summery weather. Then knock on wood, this year there's been nothing but regular weeds yet. 7 @$!#% years to get rid of it! ! I had originally planted it because it looked leafy & healthy. Sigh. Then I found out so dI'd the entire area

  11. Hi, while I agree with a few on your list (bishop's weed, comfry, lilly of the valley), I feel that a lot of the others should be used. If you really enjoy gardening and don't mind moving and /or sharing plants, some of the ones on your list will make great additions in my opinion. Some you can't get rid of when you try and those are really the ones to avoid. But if you just have to divide them to control, then I feel they are an asset. No doubt some of these are TERRIBLE, but not all. Thanks for warning others about the dangers of planting without research!

      • I always wanted drifts of Alaska daisies I finally got my dream that after growing them from seed lovingly caring for them watched them in just A few years take over my yard and my life with dead heading thousands of bunches that just seemed to appear over night one Spring 😯wouldn't you know it was at the same time I had major surgery and medical problems going on so all I could do is enjoy the beauty of my dream! Ha! Ha! Three years later there might be six bunches left if I even see a baby start I pull it right away! It was a lot of hard work to get them under control but I finally did it! Bunch by bunch! Note snails and slugs love daisies! Funny how some things can be so pretty until you look under the pretty! 🐌 All Dead Flower heads are tossed right away in the green recycling barrel. Happy gardening! Remember it's about enjoying our time with the peace you get from diging in the dirt and smelling the flowers and if we're really quiet we can watch the birds play!

  12. Good article. My unintentional perennial invader: Alfalfa! Courtesy of my bird seed feeder. It's pretty, but it roots DEEP quickly and spreads wide in any soil without additional water in our drought. My neighbors must think I'm nuts. I was outside yesterday vacuuming up millions of seeds. Beware of anything growing under your bird feeders. :)

      • Buy or make your own non sprouting bird seed. Best you do your own research on making your own but it basically involves baking regular birdseed. If I remember correctly it is claimed to not alter the nutritional value of the seed for the birds, just sterilizes the seed so it won't germinate. My problem with bird feeders was not with sprouting seeds but the dropped seeds were a buffet for mice and voles the raised havoc with my garden and invaded the house. %#€>*%#, I hate mice so I gave up on feeding the birds.

      • No to mulch. The seeds will germinate in it. I know from experience! We finally put bricks around the feeders and filled in between them with a concrete filler. Finally, no more sprouting seeds. Just sweep once in a while.
        Reply

      • Birds do not like anything at the bottom of the feeder, not even flowers. It gives "bad" animals a place to hide. When you buy less expensive bird seed there is a lot of waste (filler) that is dropped on the ground and some of it can take over your lawn. I finally got talked into more expensive bird seed. What a difference. No more seedlings under the feeder. It cost a little bit more but there is no waste and the squirrels and mice and rats are not as attracted.

It is georgous to look at it has all colors in its leaves. I tell you its roots go to China and back. No weed killer even comes close to killing it. So if you have to have a start plant it in a big urn and keep it on the patio.

        • (Chameleon (Lizard Tail) Lived on 1 1/2 acres when I first bought it. It's a beautiful plant, especially in the spring when the white blooms are on it. Made the mistake of bringing it to my new house which has a small lot, brought them over in pots, but when they started growing out of the pots, made the mistake of putting them in the ground. Now I have Chameleon (Lizard Tail) EVERYWHERE and cannot get rid of it. I have tried to dig it up, but the roots go 2 to 3 feet in the ground and if you leave the smallest crumb, it will sprout. Regret ever bringing it to my new house.

    • Spiderwort is the worst for me also! UGLY when it is finished blooming and spreads everywhere in my garden. I make a point of examining my garden every few days in the spring to dig it up when it’s ugly leaves poke thru the earth. I use a weed killer with a dropper on ones that cannot be dug out without digging out the desired plant next to it.

    • st. johns wort and vinca will grow under them, so will sweet pea. all three of them are terribly invasive and hard as all get out to get rid of though. Azaleas and rhododendron grow great under pines...blueberries and raspberries too though the raspberries can take off if you arent careful too...not hard to research on pinterest in the search line...acid loving shade plants. From what I have seen in my neighborhood (I live in a tall pine forest in the sierra nevadas of northern california) grass doesnt do well at all, mosses do do pretty well though.......and those ferns talked about. If I had my druthers I would love to do the main part of the lawn in irish moss as groundcover (yeah, here it takes off I've heard but its short and pretty enough to just be a soft short carpet) with a meandering path of flagstone and small to medium sized beds of color - mostly perrenials - here and there along the paths...a bench with an arbor ( and a flowering vining plant) over it and bubbler nearby off in one corner.

      • Vinca MINOR, if planted in a colder region, especially where it's snowy, will die back in the winter and regrow each spring. Before seeing new growth, rake the area to remove dead foliage. I have a home in zone 3, and my 20' x 10' patch under my pine and dogwood trees was the same size 20 years ago. It needs regular water in the summer. Vinca MAJOR is considered invasive. I have no clue about its use in much warmer climates where its water needs may be an issue.

As stated, up to 80' up the trees, huge roots, difficult if not impossible to get rid of. We've tried!

          • In Wisconsin, the orange are called ditch lillies because they are usually found growing wild along road sides. I think people put them there so they don't have to mow the road side and they choke out anything else that may grow too tall by the highway. I bought my current house a couple years ago and and left behind a lot of the problem plants when I moved. Love lily of the valley and the spiderwort, but they were taking over. Left behind the obedient plant and gooseneck, because I could control them in the clay of my old garden, bud knew they would cause trouble in the sandy loam of the new place. I continue to have daisies, but rip out any that encroach on areas where they don't belong. Oregano is related to mint and has the same invasive habit, so if you like growing your own, containers are the best way to control it. Love the article. Plant what you love, but remember the plant's habits and you will go far and be less frustrated.

          • Thank you for your kind and informative comment. What area of Wisconsin are you in? I've never noticed that when I've visited, but I think the ditch lilies are a great idea.

          • They're called ditch lilies here in PA too. They look pretty, fill in an otherwise ugly sight and can handle the drainage from heavy rains. But keep them in the ditch! They spread like crazy unless contained and need to be divided on a regular basis. If you have a large yard and need something that is low maintenance and fast growing in the sunshine, this may be the plant for you.

  30. some of these spread by seeds only, so all you'd have to do is trim off the spent flowers and they won't reproduce. Disappointing you'd say to straight up avoid them.
    Reply

    • What if you have a hundred plants and more are added each year? Cutting off the spent flowers would take hours. Eliminating most of the plants still provides for a good number the next year or so. Also, if you have anything growing in driveway cracks or such, pour over them a very warm mixture of 10 parts water to 1 part bleach. This should only be used where it is not an issue to contaminate the soil.

  37. I never regretted planting any of these plants. There are ways to keep them more contained in your garden and yes you have to make some effort pulling seedings but it's called "gardening" for a reason and it's healthier than taking antidepressants. I think people should grow whatever appeals to them and keep in mind that some of these plants will grow when all others will not. That's why fine gardens are filled with them.

They make great gifts/sharing....and my "invasive" flowers weed much easier than the real "weeds" For instance, I planted soapwart for a few years ago and it has scattered on the wind. I weed it out many places and just let it grow in a few. But it creates such a dense cover in the spring when the other weeds sprout that it kills them out. I wait until they are done flowering but before they go to seed and pull them out. And they are lovely and smell great!

  39. The buried container for planting mint didn't work for me. The mint "walked" over the lip to the surrounding ground. I heard for bamboo using a buried container. I met someone who kept having to dig up new shoots that multiplied quickly. I keep the mint contained in its planter by using the hot salted water from cooking pasta or the hot vinegar when I clean the coffeemaker. I pour it over the bits that try to escape the edging. After I pull up as much as I can.

    • If nothing grows there, I would actually suggest trying some of these invasive plants. You should also start adding some compost to those patches of soil (once you've weeded them). It might take some trial and error, but I'm sure one of these aggressive plants should grow in your space.

  46. hi from Washington state; the Pacific Northwest. I have noticed that nurseries and even the Big Box Store sell things on the state restricted plant list! That is horrible! Much of WA. is being taken over with Scotch Broom - which is on the list - yet nurseries keep selling it. The bright yellow flowers are beautiful and the soft little leaves are nice but it gets up to 6-8 feet high, produces THOUSANDS of seeds from one plant. The seeds get into gutters and streets, wash out to streams and rivers, sprout EVERYWHERE in the wild areas and crowd out native vegetation. It is not edible by farm animals so can ruin a pasture in just a couple of years. Please do not plant Scotch Broom! Also sold at nurseries without a warning sticker; Ribbon Grass. So pretty, green & white leaves, spreads easily with tough knotted roots. But it is a thug and crowds out everything and is nearly impossible to dig out. Plant only in containers!

    • RIBBON GRASS! It won't die the roots are so hard to pull up. Put pure concentrated Roundup, heavy plastic then mulch and it still came through all of it and spreads to actual grass. I would rather have daisies, dandelions, mint and clovers

  47. I've grown a few of these and enjoyed them. In South Central Alaska, The Valley, I've grown golden raspberries on part of a fence -The kids enjoyed them just to pick and eat. I also had arctic iris. They would come up and bloom just as the bleeding hearts would cascade over them. It was pretty for a couple weeks. Then the delphiniums would start their show etc. Perinatal beds are great when you get them timed right. Oh...here in Arizona now, in the high desert where it will be over 110 for the next several days. I grew hollyhocks and enjoyed them in the spring. I've had one plant that just wouldn't quit. I dug them out. Had them dug out but there was always one sweat potato left to take off and cover the whole bed. I finally plugged up the emitters on the irrigation for that bed. The sweat potatoes are pretty but are too thick a ground cover for here. I prefer things here that grow up and keep the ground clear. I like vining plants like star jasmine, pink jasmine, banks rose and tangerine beauty.

  48. I live in Knightdale, NC, and I have one of these 'regretable' plantings. I just don't know what it's called. I inherited it when I rented my home. Little pink flowers on a long stalk, with 'silver' fuzzy leaves. I'm finding them everywhere! I also have the yarrow, but it's not over taking it's spot. I don't know what zone I'm in, but I'm near the Capitol of NC.

  49. My personal list of 'promiscious' plants: Aquilegia (colombine) Feverfew Crocosmia Virginia creeper is pretty easy to control with a secateurs. It is very 'curious' though and likes to explore. So it will get in under fascia and soffits, travel into lofts looking for light and then send shoots back out again under the apex of roofs.

  50. I'm reading this and smiling. What a difference zones make. I'm in zone 8a, and our yearly temperatures can range between 14 and 114 degrees Fahrenheit. That's not a typo- if our winter doesn't kill it, summer will. When it rains, it floods. Mostly it doesn't rain, and things catch fire. My soil is 10-18" of alkaline clay over solid limestone. Gardening here is a constant search for "what plant refuses to die" and it's mostly an exercise in futility. I think I've killed about half of the things on this list- by accident. There's a handful you mentioned that are toughing it out (with shade and irrigation), so I'm going to go shopping for a few on here I haven't tried. I'd add anything in the amaranth family, and prickly pear cactus. Unless you can eat them faster than they can propagate.

I've lost track of how many plants I've accidentally scorched cause the tag says full sun, but the poor plant can't handle it here. On the flip side, some of the hydrangeas I planted on the north side of the house didn't survive the cold snap we had back in January. I even struggle getting native plants to survive here! *sigh*

  52. I disagree with many of the plants listed here. Groundcovers are supposed to cover the ground, if they get out of your beds mow them. I moved into a home that had a lot of these perennials and they have matured into easy to maintain old garden beds that may require weeding once or twice a season. Used underneath flowering shrubs or specimen plants, they can be quite lovely and reduce the need for weeding and mulching. Despite their invasiveness, they still have either beautiful flowers or leaf texture/structure or can be important sources of pollen for bees. In the right application they can be lovely (such as naturalizing an area that you may not have time to maintain and don't want to mow) Many of them used in conjunction with each other provide nice textural contrasts as well as beautiful flowers and can keep each other in bounds. Perhaps this is just my ground though. I have not found many of these difficult to control and love that they compete well with each other and provide a nice textural structure without a lot of messing around, allowing me to focus efforts on establishing the specimens such as a garnet laceleaf japanese maple (which by the way the lillies of the valley work wonderfully underneath).

    • You're right. If you love it you should plant it, and these plants have their place. When I wrote this post I had the inexperienced gardener who wouldn't be as likely to keep up with their weeding and garden maintenance in mind. (And an overgrown yard teeming with bell flower, ferns, and lily of the valley that I'm still trying to get under control, lol.)

    • Lucky for you that you can mow them. Many of us in the desert portions of the US have dirt with a huge percentage of rock from pebble size to basketball size. You can't rake them as it just unearths more. Pick them up? You're kidding me! Sometimes I see a 4" rock that I can't unbury because what I am seeing is only 10% of its actually size. Mowers and rocks do not mix well, and trying to mow a rocky area is dangerous. This goes to show that what one person considers to be an obvious solution is impossible for others to implement.

  53. Hello Kristen and global friends: Thank you for sharing these information with us and I totally agree with you since these certain "Perennials" can take so much space in your garden. However, in my case, I welcome them especially the Sunflowers. Last year, the birds, the butterflies and other living creatures, like us, do enjoyed them especially on Summer and Fall. This Spring and Summer, I transplanted these variety of "Perennials" in paper Solo brand soup cups and gave them away to our Scarborough community residents, as well as in our churches. These "Perennials" found new homes and we will be celebrating our Canada Day 150th Birthday! We also managed to raise funds for food banks and shelters. So, if we can't overcome them, then let us welcome them help us fund the needy community members. God bless you all!

  54. Haha my mother in law's garden is about 2/3 ferns, irises, day lilies, raspberries, Lily of the valley, and anemones, with a small patch of California poppy and the odd volunteer lettuce. The rest is fireweed that she cuts a maze into for my toddler to pay in. It's a bee's paradise and I love the wildness of it. Aggressive plants are great for a laissez-faire gardener ;)

      • I planted most of those invasive plants and then some (Lamb's Ears, Hops vine , also invasive, and other plants that were given to me over the years). While I loved many of those plants, after a while they took over and I eventually got rid of most of them. I still have Lamb's Ears and Yarrow. I have quite a big garden and that is my problem. It got difficult to manage. But if you love any of those plants, you have to keep them under control by either growing them on their own in a separate spot or digging out shoots to keep them from spreading too much or as some of you mentioned, growing them in pots.

  60. I'm in 5b, so some of these are well behaved enough. Every very year i am cursing the day i planted Virginia Creeper. I started yanking it out about 5 years ago, and all through growing season I'm on the lookout for seedlings to pull. However, I also have the variegated variety which is very well behaved and not invasive at all, nor does it reach as far, and it's gorgeous. My #2 worst idea has to be planting Mother of Thyme. It's a mother all right. Just not the kind I want. It. Is. Everywhere. There are probably others, but those two top my most hated list.

  62. Love this site! Found it on Pinterest. One of your hated flowers, the daisy, is one of my favorites, but I haven't found it to be very invasive. Bought some Becky Daisies from an online nursery which bloom all summer long for me, and wanted more of them. Tried saving its seeds and planting, but they wouldn't come up. The Torenia is another that can be -- quite literally -- off the wall. At one time had them all over my yard. As far as the short-bloomed flowers, they are so beautiful even if they are temporary, that may make them worthwhile! But then aren't we all "temporary" and short-lived? Please check out my take on the temporary at http://wp.me/p8djUc-1g

  72. This was a very interesting post. I live in WV and I can say that although many of these plants are invasive here, they have not taken over. I love, love, love my daylilies. I have about 20 different varieties and they bloom for nearly a month. Not all at once. And although each bloom only lasts 12 to 15 hours, each plant will bloom for nearly 3 weeks. I have a few re-bloomers too. I find them attractive even when they are not in bloom. Virginia Creeper I have to admit is horrible. Deep roots and often has poison ivy mixed in. That and wild grape vines are very hard to dig out. I love my wisteria though. It provides a lovely canopy for our hammock. We give it a good pruning every year right after it blooms to keep it in shape. But mind you never cut off any sucker from a root. Get a pair of pliers and wrench it off to prevent future suckers. That goes for many trees too. Never cut the sucker at the ground or root. twist it off. I am aware of mint so I just got some chocolate mint and put it in a planter. My cousin had some in her yard and every time they mow they still smell mint. Not such a bad thing. We have very heavy clay soil and so many of these species are controllable. I don't have a problem with ferns. I try to grow them along the northern side of the house but it takes so much effort to amend the soil that I only have one. I have had a problem with arium itallicum. It is a bishops hood or jack in the pulpit. I keep a nice patch that I can see from the window in the winter. It is a green as can be with a foot of snow under the leaves. But the birds eat the berries that come from the "hood" in late summer and have dropped them in places I don't care for them to be. When they become overbearing, I don't let the berries ripen and I will pull a few out to make more room for my hostas that I defend from the deer with Liquid Fence. It is either that or a gun. But I live in the city so.. no gun. My sister always loved lily of the valley and had a shady area she just let it take over and it smelled and looked lovely too. So s you say to each his own. It was enjoyable hearing your stories.

It's an ugly garden but the veggies are beautiful. I just can't convince any of my neighbors that this is a good thing. My regret is oregano.

  77. I have a tiny yard in Maryland (10 x 10 yards). There I grow many of the invasive plants from the list (yarrow, bee balm, daisies, day lilies, campanula, irises, hairloom mums, anemones, Lilly of the valley, ferns, etc.) All of them are invasive in our climate. My trick for peaceful co-planting is to plant them in containers in the ground. I take large plastic pots (2-4 gallon pots left after planting trees or, better yet, large empty buckets from cat litter). I cut out the bottom and dig that bottomless bucket into the flower bed. It is important that the walls of the bucket go down more than a foot and stick above the ground couple of inches. Then I fill it with soil and plant the misbehaving plant inside the bucket. The plants can grow their roots down, do not need any extra watering or feeding, but they cannot spread out. You still need to deadhead to prevent reseeding.

  78. I found the article very misleading, where you live often determines what is invasive and what is not. I have many of these plants and do not regret planting any of them. When I lived in Southern Ontario I did find that Chinese lanterns spread quickly but when I lived farther north I could barely get them to grow. That is just one example. And if something spreads where you would rather not have it, simply yank it out!

  83. Thank you for Perennials You Will Regret Planing. I wish I would have had this information many years earlier. It would have saved me countless hours digging and pulling and even a terrible rash from the Japanese Anemone. I would add a caution for Black Eyed Susan/Rudbeckia. It has over taken one raised flower bed and is now spreading to the one below it. It is very bright and cheery but definitely needs work to contain.

We had a tarp over it all season, we won. My neighbor was selling it as "Bamboo" at a rummage sale, I shared my experience and now we are are great friends. Keep cutting it down so it dies out. This stuff will break through concrete to survive. We do not want this evil plant to spread along creeks and rivers, it will be Pampas grass all over again! I am confident it is on Michigan's invasive list. Maybe call your local University Extension, Master Gardener Office they will advise you. We are in SE Wisconsin.

  88. I find it rather sad that so many of the plants listed, really attract the pollinators. Funny how we're told to grow dandelions but not clover and a few others you mentioned. Personally, I think temperature, soil obviously - (I have heavy wet clay most areas or thin soil over bedrock) and a preference to what kind of garden you want, are the major criteria. I prefer flowers and gardens to lawns , which are expensive, heavily water dependent and don't give much back to nature. I'd rather see a plot of wild flowers growing and bees, hummingbirds and butterflies than being concerned about what is in the garden. I live in zone 4a in northern ontario.

I was surprised to see ferns growing out of other pots so I would just yank them out. This year they tho there are more than last year. I just yank them. I spent the last 7 weeks repotting plants into BIGGER pots. I dont have much experience gardening, I just get what I like and what will grow in a pot.

  101. As someone with a degree in plant and soil sciences and an agricultural extension employee I find this article troubling. This is click-worthy, but a negative message overall. Spreading personal preferences off as “bad species” advice promotes miseducation about ecology. I expected an article on ecologically damaging or dangerous plants, but this turned out to be a little overwrought. Experienced gardeners know: You need the right plant for the right place. Vilifying plants that self propagate is over-simplified. The foremost landscape designers and architects are gifted in working with drifting populations of spreading perennial and shrub species. It’s perfectly okay to not have time to maintain tight lines, or have a small yard, or dislike a natural look, or be a lazy gardener. I qualify for three of these four. But I would never tell people that plants I don’t like because they don’t suit my needs are bad and they shouldn’t use them. Please educate yourself about plant selection, garden design, and ecological landscaping from reputable sources and stop influencing people’s relationship with nature with misinformation. The environment needs a break.

I tried to put disclaimers on it, and if you've read the comments, there are many people who disagree with what I've written, to which I've often replied--if you love it, plant it. It doesn't matter what some random-person-on-the-internet says. Many of the garden bloggers that I follow don't have degrees in horticulture, nor do we profess to. I think it would be a wonderful idea if you would start a garden blog yourself. There's definitely a niche for garden blogs written by people with an education in plants and I'm sure you would do an amazing job. Please let me know when you do and I'll be the first to follow you. (I'm not being sarcastic.) Happy gardening! Kristen.

    • Whoa! This is a fun blog. People sharing their experiences with plants that grow in their zones or invade the yard depending on where they live, soils and other factors. This blogger was not “influencing “ anyone. It’s a lively exchange between gardeners.She warmly agrees that the plants she finds invasive might not seem that way to others. She’s telling us what she doesn’t like. So many times she agrees to plant what you love. She in no way even suggests she’s an educated expert. Although, you, Jessica, come off very snobbish, dour and wanting everyone to listen to your educated, reputable advice. Most of us don’t want to play with you. Too opinionated and self important. Nah, we’re having a good rapport with Jessica. And her sense of humor. And graciousness. And kindness.

  102. I live in Colorado Springs, CO where growing things can be crazy, you don't know what will come back once planted. I have Holly Hocks and have for the 7 years we have been here. We love them. No maintence. During winter we do cut them down to the ground but they do come back every year. Tons of blooms. Bees do love them so don't plant close to your doorway. Yes, it replants its self and also the birds spread the seeds some but that is not a problem. I am growing many mints. Some in a raised bed and also pots. I think if you keep up on trimming them back then they do not take over. As for me that is. Love Sweet Mint and we use a lot in our sweet tea. I dry a lot of my mints and herbs and use them in foods and they last into winter. I dry them by just laying them on a paper towel and leave them alone, when dried out then put in a container with lid. My Lemon Mint has not really taken off like this article said it does. I do have it in a pot.

  103. I am in Illinois, and I just bought some pink Lily of the Valley because they were so different. I will be putting in a container since I've seen how they can spread as a shade cover. Also, I found some wild Violet in a neighbors lawn that was white with purple inside - so pretty, until it took over my entire garden. I planted 4 small blooms and now it is literally everywhere! The standard purple Violet can be super invasive. Such a shame since they only bloom in the spring. Just wanted to add Violets to the list :)

    • I've never heard of pink lily of the valley! I wonder if it would spread as much as the white variety? I ask because with day lilies, it seems to me that only the common orange variety has a spreading habit, not the other colours.

      • Convallaria rosea is the name I found for them. I was thinking they would be so pretty, but also wasn't aware they are TOXIC to pets. I have a dog, and we have a stray cat that hangs around our house. So I need to put them somewhere outside of the yard. I will be planting them in the spring.

  104. Thanks for the post! My yarrow & daisies behave nicely, but my raspberries are out of control! lol My unintentional invader: Verbena Bonariensis. Great structure plant, but oh my!, just one season & it reseeded in the next three yards down the street. Avoid it.

  105. I really enjoyed this article & I'm glad I found it! Congratulations on going viral :) The comments were great to read also -except for the few naysayers & you handled yourself well! I've probably spent 45 minutes, reading intently! Lol... I'm in Michigan, zone 6a. I've either fought or embraced quite a few of the plants on your list and ones that commenters have mentioned, as well. I'm also enlightened about a few others & I thank you (& everyone!) for that. But... I never knew people actually planted Virginia Creeper on purpose! It's always been a weed to me? :) Rudbeckia, Siberian Iris & Cranesbill Geraniums are what I'd add to the growing list. ps) this thread has been going for over a year!!

    • Thanks so much for your kind comment! Every time someone mentions planting Virginia Creeper in a gardening group, I shudder inside--especially after hearing everyone's stories. I also love hearing what is a problem in other zones than I live in--it helps me be a better writer on this blog and be more sensitive to what might or might not work for all my readers.

  106. I have Hollyhocks that have taken over a new perennial bed that I've spent more $ then I care to think about on. I'm not opposed to the hollyhocks, just that they cover everything with their huge leaves the first year b/4 they bloom the second year. Can I cut back the leave to give my new perennials a chance to get started and then move the hollyhocks next spring to a new bed? Or will they die out if I cut them back now in August. They're a biennial so takes 2 years to bloom.
    Reply

  107. I can agree with you on most of the perennials. We live in South Carolina now, but lived in Illinois for almost forty years. Early on in those years, I planted spiderworts, hollyhocks, lily of the valley, bee balm, and others, but the absolute worst one was snow on the mountain. I called it my plant from hell. Whenever I would dig it up, I through it in the field behind us. It didn't matter if it landed upside down or not, it would come back the next year. So yes, unless you can have a spot dedicated to one of these particular plants, don't plant them in the ground. I love all plants, well maybe not all, but I am a lot more careful what I plant here in the south. I am enjoying many plants I've never grown before.

  108. This had me giggling! I do believe I have everything growing in my yard, however I doubt I planted it all! I also have traveled across the country so much that I have learned there are multiple names for the same darn plant. And that what is a perennial here is an annual there. My personal love/hate relationship? Creeping Jenny. Oh my goodness! This is my favorite/least favorite return! I LOVE that bright green. I absolutely did not plant it over there, or there, nor in that container, or that one! But golly, it's pretty. Oh my, look! Creeping Jenny on CLEARANCE. I'll take a dozen! OH NO! I have no where to put these. And so on. I'm at a weird point in my life that I can't part with the weeds that are strong enough to support the Morning Glory that I didn't plant. It's a beautiful hot mess. Some folks are restricted to rock gardens. I'll take this beautiful hot mess. I grew a pear this year! After a two year wait. I made a pear! I'm so ok with everything happening in my garden. I want to meet the person who plants clover on purpose. I want to buy this person a drink and ask many serious questions about life. This person MUST know some serious stuff. Because, CLOVER? Just thinking outloud.

  109. I am struggling with Perennial Bachelor's Button. It has completely taken over my lawn and now it is spreading to my lawn! I didn't even choose to plant it! It was sold to me as an Aster plant which I love!
    Reply

  110. I think you are confusing perennial with low maintenance... You list many of the plants as terrible because they spread and overtake your garden in a couple years. In one example in 5 years! That is a long time to not maintain an area. Yes, they will grow. That is what plants do. Do not say the plant is bad just because you do not want to / have the time to maintain it.
    Reply

    • Hi Susan, you are right, no plant is "bad" per se. This article was written to be slightly humorous and for the person who is new to perennial gardening and might not realize how much work it can be. As I've said many times before, if you love it, you should plant it.

  111. This made me want to run out and grab most of these plants for my garden! Hardly anything grows well st my place. However you forgot Wisteria. You must not have any experience with that. Leave it alone for s minute and it’s from the devil.

    • I bought a non-invasive wisteria. It has been 4 years now and it is still only about 9' at it's longest runner and very sparse. It finally has about 1/2 dozen blooms this year.

  112. Study everything about pollination and most of the 28 plants you listed are great for our pollinators , who supply 60% of our daily food, but hang around and they will disappear on there own as soon as the Bees and other pollinators are listed on the list of extinction?
    Reply

    • It's true that all of these are great for pollinators, and if you love them you should plant them. This list is intended for a newbie gardener who might not be as vigilant with their plants and easily get overwhelmed by a plant that didn't produce as expected or overtakes a yard with a year or two of neglect. There are many other plants you can plant that are equally as good for pollinators.

  113. Don't forget Russian Sage (Perovskia Atriplicifolia) which quickly outgrows anyplace you plant it and trying to dig it out is a monumental effort. May Night Salvia (salvia x sylvestris 'May Night') which prolifically reseeds into your lawn.

  114. Please use caution reading this list. Most are fine. If you really want to know which ones are invasive, check your DNR state website for an official list of plants to control.

  115. Thank You! Fascinating ! I always thought our difficulty in growing the plants you mention was our " cold" zone 4. But you have a MUCH colder climate and this Fascinates me! I feel lucky to be growing my ONE daisy in my greenhouse! Which is why I have a greenhouse filled with Bouganvillea, hibiscus, petunias, fushia, canna lilies and geraniums, jasmin, amarillas, carnation, chrysanthemum, and about every plant that blooms and it is crazy flowers out there and it is almost dec. but why can't we grow outside like you? What ? We can grow annuals like crazy? I think what I learned is that saying my Grandma taught..."A WEED is a Beautiful Plant growing in the wrong place" But it makes me REALIZE there is No SUCH thing as a weed! We were cooking in Rising summer heat because the afternoon sun hits entire side of our house. Husband was talking air conditioning. I wanted to plant a big tree but our old sewer line would be below it. Our neighbor invited us to have ice tea on their back porch covered by Virginia Creeper. SO Cool!! The leaves formed a canopy and transpired cool refreshing air. We came home and built a mesh trellis that went up to roof of our house and I bought Virginia Creeper. It was slow to cover but 2 nd year we sprayed the Tunnel it was forming with water on hot days.....no air conditioning needed. It has made a nice canopy over the decades if a runner tries to strike out across the lawn ( rare) I lift it up and secure it to the trellis. Even with temps now in 100's the house stays cool all day and I don't even spray leaves with water....if someone bought our house and had the belief that Virginia Creeper was a weed and took the trellis down they would be burdened with expensive air conditioning bills from then on! So I guess I would say Grandma was right....live with your plants awhile and See how you can maintain Harmony in the unique conditions you live in....how to make your " Weeds " work for you.

    • One thing I learned since writing this post is that these "problem plants" are certainly not problems everywhere. I also live in a place with generally fertile soil, so that might also be why some things run wild here that don't do as well in your zone even if it's warmer. I love your grandma's saying and the story of your Virginia creeper. What a fabulous example of using a plant to your advantage!

  116. Princess lillies. The ones that just grow in a shrub on the ground with little lilly flowers...I planted two about 6 years ago in our first house...after pulling them out and spraying them, they've come back multiple times and are just spreading and spreading.....

  117. My big mistake was Salvia Coccinea, or “Coral Nymph Salvia”, one of the Texas Salvias. It’s a beautiful coral color, and the Hummingbirds love it. In my zone 8, the host plants die but they are prolific re-seeders — and will pop up anywhere.
    Reply

  118. Well, I love the way my ferns look popping up here and there. They complement the hostas in my shady woodland garden and the ones I have don’t seem too aggressive. Maybe that’s because I have clay soil and also because I cut all the fern fronds off - right down to the ground every year in mid February or early March. This way, they don’t get overly bushy. On lily of the valley, I totally agree it is invasive, hard to pull up and not even pretty! You’re also right about daylilies. I mean, I grow them, but the foliage does take up a lot of space, the bloom colors seem washed out and don’t last long. I read somewhere that each day lily blossom only lasts one day. Yes, irises are also short lived, but I really like the deep purple color of my tall Siberian iris. They look so pretty bending over the front-yard birdbath, so I’ll keep those. Besides, they’re fairly well behaved and the foliage makes a nice backdrop for annuals. I can easily dig up a clump of iris to fill in a bare patch for next year - I don’t have to dig a huge hole in the clay soil - just partially cover the tubers and they’re good to go. I agree about bee balm, though the red one can make a nice punch of color. Appreciate your advice on some of these others (especially Veronica. I was considering it, but now I’ll stay away from it). In my experience in my garden, Lady’s Mantel is awfully invasive and pops up all around my stone pathway. Also, a terrible groundcover called adjuga - I think that’s how it’s spelled - anyway, it will get away from you if left unattended and it’s so ugly it’s not even worth it! I do hope the beginning gardeners reading this post will at least try growing a rose or two. We gardeners mostly learn by trial and error. Roses present a challenge but also can provide many potential rewards. Oh yes, and unlike one of your readers, I love black eyed Susan’s and highly recommend this cheerful garden perennial.

    • Malva is my most hated invasive plant. Thought very pretty, it popped up everywhere and was impossible to control. We moved 7 years ago..I bet that bed is 100% malva now, lol. People who are hating on this list, please keep in mind Kristen’s zone(and no doubt space) most likely has a lot to do with her choices. As she states, the advice may not necessarily be for you! I planted lily of the valley at the end of the driveway and yes it has spread everywhere but I don’t care because it’s contained by a driveway.

  123. Thanks for your list. I live in a totally different zone, so have local unique problems. Many of the plants you list are not a problem here, others are. However, we have some you don't list that can take over our entire garden in one year. What I suggest to people I meet who are just starting into gardening is to visit their local agricultural extension agency (in the USA) and do searches on the net, for their zone, for invasive plants. They can also do searches for plants that do well in their zone and their soil conditions, as well as light requirements. Local garden clubs and master gardeners are also great resources here in the USA. As well as blogs like yours where the property is located in the same growing zone.

  125. I found this on Pinterest, and although it’s an interesting read, I’m a little concerned. Many of these plants attract pollinators very nicely, and are doing a huge service environmentally speaking. We really need to work to keep the bee population, and plant native. I hope people aren’t influenced against some of these plants, just in order to keep down maintenance in the garden.

  126. Bell Flower was here when i moved in over 12 years ago. I have dug, sprayed, pulled adn never let it go to seed but it is still here! Seeds can stay dormant forever and it also spreads by carrot looking tubers. And the lambs ear I planted from seed Holy crap! EVERYWHERE!
    Reply

  127. I couldn't help but laugh at your list. The loveliest (and lowest maintenance) garden I ever had included almost all of them, all competing with one another under a grove of young walnut trees. Only the virginia creeper ever got out of hand, and that wasn't until a well-meaning neighbour mowed the blackberry patch it was competing with.
    Reply

  128. As others have said, I'm sure new gardeners appreciate this list for knowing commitment requirements. It also truly depends on your zone, soil, environment, etc. My mom has an area of lily of the valley that's been there over 50 yrs. It's never gone out of bounds. At my house in the same zone, it went crazy, but I have vincas that stay neatly mounded, as does snow on the mountain. I'm in zone 4, so growing season is short; I assume that's part of it, but it is odd how plants perform in different neighborhoods even. I've never minded taking a day to clean up overgrowth of raspberries & many other plants on this list; the reward is worth that. My personal nightmare is Creeping Charlie. It takes over the garden, lawn, and woods out back. It's easy to hand pull, but I can think of 1000 things I'd rather do! Yet I see people buying pots of it at plant sales who say they use it where they can't get grass to grow and haven't had an issue.
    Reply

  129. I live in Ontario in zone 5b. My garden has been on garden tours and I can't agree with you more about some of the plants on your list. My home was a century home and pretty well the only thing I let run are the double red poppies that were planted after WW1. They are beautiful when blooming but incredibly ugly after the blooms are spent so I hide them with another prolific bloomer orange daylilies. They are contained to one area. As for lily of the valley, they will destroy your asphalt driveways and kill off other plants if you let them do their thing. I try to go by the rule, beautiful but deadly. I love daylilies and have found varieties that bloom at different times for a continuous display of colour during the growing season. They still need dividing every few years, though, and you can run out of places to put them or people to give them to. It's not fun to put them on the compost heap. While many of the commenters here have negative views regarding your choices I think you are doing new gardeners and even experienced ones the push they need to get rid of some invasive plants. The reality is that too many people are focused on the beauty of the plant and not how it cooperates in its setting. So many plants that are not native to north America have pushed out native plants to our detriment. I cite most ornamental grasses in that category that have destroyed some of our wetlands or bogs, displacing bull rushes, etc eliminating nesting sites for many birds. I am lucky enough to have an area behind our house, well away from us where I let comfrey (I could open a soap factory!), ferns, raspberries, etc to go wild. Two perennials you forgot though, are bugleweed (ajuga reptans) a beautiful plant that spreads by runners with bronze coloured leaves and small purples spires reaching only six inches high and Siberian squill (scilla). Enter at your own risk when planting these. I moved from that century home last November and have a DO NOT BUY LIST for my new home which includes almost all the plants, with the exception of daylilies, on your list! I classify your list as a public service announcement.

  130. I love what you pointed out about Chinese Lanterns and Virginia Creepers being so prolific and often difficult to kill. I imagine that getting rid of those plants or other problematic garden features like rotting trees can be a real pain. My sister has some of those problems in her yard and is looking into getting professional help to make it a little easier!

  131. There seem to be so many haters posting comments. I agree that some of the cautionary plants are lovely, but knowing a plant has a tendency to take over a garden is exceedingly useful information. I LOVE daisies and would be perfectly content to have them take over a part of my garden, but now that I know it would/could, I can decide if I want to deal with that or not. I really appreciate the information. What's that saying, 'forewarned is forearmed'?

  132. I enjoyed your post. Sadly I have a terrible problem with daylillies. I've dug them out so many times now! I'd also like to mention Delphiniums. I had maybe 10, 5 years ago. Now it's a jungle out there. I dug them out last year and this year they came back with a vengeance. I have over a hundred of them!.

  133. Oh another one that I hate is clethra, also known as summersweet and pepperbush. was very well behaved in my garden bed for about 5 years, then it became possessed and raced around my walls into other beds. A landscaper tried to get it out but couldn’t. It has a brain. It knows where to hide. It hides behind my hydrangea bushes that are foundation o Kant’s, them it suddenly pops out from under the hydrangea like Alan Arkin in Wait Until Dark. (Old movie reference). Now I can’t get under there to pull it all out because my bushes are all leafed out and blooming. It also attracts large black stinging wasps or hornets....creepy bugs. Ferns are a problem for me. They grew under my porch for years then suddenly jailbroke one year. I used to let some wild goldenrod grow because it’s a good late bloomer for pollinators, but it crowded out other plants. I even cut it back in June to try to keep it at a decent height, but it does what it wants.. it’s crowded everything out. I also have a problem with caryopteris. A very hoity toity landscaping firm planted it my front garden bed as a “flowering plant.” It pretty quickly became a bush, then a very unruly, woody shrub.. it is too big, with its unattractive, twisty woody parts, for the front of the garden. But it too is a late-flowering perennial for pollinators, attracting the last of the summer bees.in vast numbers. I picked a piece of it off and placed it in the back of my side garden where maybe the shade will hold it back a little. Then I shall slay the mother ship plant. My neighbor planted some kind of beach grass in her back yard. Next thing I knew it was growing next to my pool. Then, there was one in my backyard. I think it’s trying to grow in my lawn. Meanwhile, the neighbor got rid of hers.

  135. Hello Kristen - Liked the article. I think it's useful to know if plants will invade your garden, no matter how pretty they are. They can so easily become a nuisance instead of something giving you joy. My personal (un)favourite is wild raspberries. We moved from Ottawa to Woodstock, Ontario last year in September, and I discovered in the spring that the previous owners had planted wild raspberries in the back corner of the yard, and had allowed it to get out of control. It was wandering everywhere, including into the two neighbouring yards. I spent 4 days digging up the plants and as much root as I could get to (a bit of rain two nights helped!) I will help the two neighbours clean up as I think it will reduce my own work in the future. I have found websites with info for growing raspberries and containing them, but unless one is crazy about them, after my experience, I would advise people against them. The wild raspberries have very small fruit, are prickly, and look extremely untidy at the best of times. While searching on the internet for the best ways to get rid of these prickly nuisances, I read a horror story of someone in the US who had bought an old house which had a 4 ft wide 100 ft long hedge of wild raspberries in the back yard - took YEARS to get rid of them. I have bookmarked your website, and will acquire additional plants for our garden with great care.

  137. "Roses - While not impossible to grow, especially if you choose a variety bred for the prairies, it is best left to more experienced gardeners." I got an "Explorer Series" rose hybrid last year from Canadian Tire -- the "John Cabot" rose. It was specifically created in 1978 for the harsh Canadian Winters (Zone 3). I have read from others they are low maintenance, and have a very high resistance to diseases. So, I guess I'll find out if it's true they are hardy and maintenance-free this spring (5 months from now), as I did absolutely nothing last fall.
