You asked for it and you got it: a list of the most-loved perennials for Zone 3. These perennials are the stars of the garden, blooming year after year and delighting their owners every time. Pick these winners up at your nearest garden centre, or ask a friend with a more established garden if you can dig up a few.
A huge thank you and shout out to the gardeners in the Gardening in Saskatchewan Facebook group! This post would not be possible without you. If you’re in Saskatchewan and not in this group already, you need to join. I’ve learned so much from the more experienced gardeners there who are so generous with their time and advice.
Best Cut Flowers
Asiatic Lilies
Asiatic lilies come in every colour and combination and are easy to grow. Put them in a sunny spot and they’ll flourish year after year.
Hydrangea
I’ve had poor luck with hydrangeas, but I know many others who’ve been successful. Look for a variety that can withstand prairie winters. Did you know you can change the colour of your hydrangea? Learn how at Garden Therapy.
Peonies
Like any other millennial, I am OBSESSED with peonies. I also happen to have no less than 8 plants in my yard. Last year I went a little peony crazy and made a whole bunch of easy flower arrangements with them, and I plan on doing it again. I also made this guide to growing and using your beautiful peony blooms.

Delphiniums
Delphiniums are stunning along the fence of your yard, as they grow to around 5 ft tall. Be sure to stake them or provide a cage for them if you plant them in a windy spot.
Iris
Although the blooms tend to be short-lived, irises are a gorgeous addition to your garden.

Lupins
Lupins are a keeper because they bloom all summer long. They come in a variety of colours and are beautiful in floral arrangements.
Limonium
Foxglove
While foxgloves are stunning, they are also poisonous. Hold off on planting them if you have small children who tend to put everything in their mouth.
Baby’s breath
The staple of florists everywhere.
Heliopsis
Heliopsis can grow quite tall, so put them in the back of your border. These flowers are a less-invasive alternative to daisies.
Goldenrod
My favourite time of year is in late August and early September when goldenrod fills the Saskatchewan ditches. If you’re going to be a weed, you might as well be pretty. However, when I plant it in my own garden, I haven’t had a lot of success.
The Shade Lovers
Hostas
Hostas are the stars of any shade garden. They come in many beautiful patterns, are slow to spread, and have beautiful white flowers. Have a bare spot with little to no sun? Hostas are your solution.
Bleeding Hearts
Whether you get them in white, soft pink, or the classic dark pink, Bleeding Hearts are easy to grow and add colour to your shadiest spots.
Siberian Bugloss/Jack Frost
Heart shaped leaves and dainty blue flowers? What’s not to love? Learn more about this plant on Fine Gardening.
Ladies Mantle
Lovely lime coloured flowers add interest to your shady spots.
Ligularia
Ligularia can grow to around 6ft tall, so place it along a fence! While it will grow in complete shade, it does better if it gets 3 hours of sunlight a day.
Bergenia
A lovely old-fashioned perennial with long-lasting blooms.
False Spirea/Astible/False Goat’s Beard
It goes by many names and is sure to bring colour to your shadiest spots. Pick one up in white, light pink, and dark pink.
The Controversial
These picks made the most-regretted list, but they don’t have to be a mistake in your garden. Just make sure you keep these ones contained, or embrace the growth.
Daylilies
Daylilies come in every colour and combination imaginable. Avoid the orange ones pictured here if you want to avoid spreading.
Hollyhocks
Hollyhocks are a stunning and tall flower that comes in many beautiful shades. It spreads quickly, so keep it contained to one spot if you don’t want it to spread.
Yarrow
Yarrow is perfect for floral arrangements, but impossible to get out of your lawn once it spreads.

Poppies
Poppies make the controversial list only because they easily get out of control. They’re so pretty though that you probably wouldn’t mind if they did.
Ferns
As of today, I have pulled at least 82 ferns out of my backyard this year. No, I’m not exaggerating, and no, I’m not done. I personally hate ferns, but I know that many other gardeners love them for their shady spots.

Veronicas
Veronicas stay in bloom for most of the summer and look beautiful in floral arrangements. Some gardeners in the Gardening in Saskatchewan Facebook Group report a huge spreading problem, and others do not.
Fun-shaped Perennials
Allium
This gorgeous member of the onion family is sure to add interest to your yard.
Sea Thrift
Columbine
Columbines come in a wide range of colours, bloom for a longer period of time, and tolerate shade.
Liatris/Blazing Star
Achillea the Pearl
I wish I could have found a free stock image of achillea the pearl, because it’s sweet white flowers are so beautiful. You’ll want to add this stunner to your garden. Find seeds here.
Blanketflower/Gailardia
The vibrant combination of orange and yellow adds some much needed colour to your garden.
Sedum
Sedums come in so many shapes, sizes, and flowering options that you won’t be able to pick just one.
Balloon Flowers/Platycodon
Balloon flowers literally have a flower within a flower. When closed they are in the balloon shape that gave them their name. Children adore this plant, so consider getting one if you have small children or grandchildren.
Spring Blooms
Plant spring bulbs in the fall so you can enjoy beautiful blooms in the spring.
Tulips
Tulips can be found in almost every colour and combination. I still love the classic red and yellow, and nothing else quite says spring to me.
Crocuses
Plant crocuses in your lawn for an early hit of colour. Don’t worry, they’ll be done blooming by the time you actually have to mow.

The Best Cut Flowers For Your Garden
Daffodils
Shrubs
Spirea
My mom’s spirea has often been the victim of many floral arrangements. I personally like the variety that has pink flowers and lime coloured leaves.

Weigela
I have a feeling that if I owned a weigela, it would also be the victim of many floral arrangements.
Lilacs
Purchase a lilac for the beautiful scent of spring. Scratch that. Purchase three, so you can have one in white, light purple, and dark purple.
Roses
Roses are beautiful but do require maintenance. Beginner gardeners should wait until they have a bit more confidence in their skills before purchasing one. If you’re in Saskatchewan, be sure to purchase one of the Morden varieties developed for the Prairies.
Double Flowering Plum
These are the the most beautiful pink bloomed trees of spring. You’ll definitely want to pick one up if you have the space. Check out this Calgary-based company for a place to order, or your local nursery.
Edible
Chives
Delicious and beautiful. Use chives in the place of onions in your recipes.
Chocolate Mint
Unlike it’s cousin the mint plant, chocolate mint does not spread!
Asparagus
If you plant asparagus, don’t expect to eat a meal from it until three years later.
Sage
Sage is equally good in soups and stews as it is as a filler plant in a flower arrangement. It’s also quite hardy and can withstand frost to around -5 celsius.
Borage
Borage is an extremely useful plant for both edible and medicinal purposes. It makes a wonderful companion plant in the vegetable garden.
Groundcover
Sorry for the lack of pictures in this section. . . I guess ground cover perennials aren’t a popular photography subject. I’ve provided links to pictures on other sites.
Creeping Phlox
A gorgeous filler plant that looks especially stunning in a rock garden.
Mother of Thyme
Learn all about mother of thyme on Wikipedia.
Silvermound
Silvermound is maybe a bit of a stretch for a ground cover, as it does keep its clumped shape. However, it will spread. It’s super easy to grow and will survive the hottest summer days.
Golden Globe
A lovely ground cover with beautiful small yellow flowers. Learn more at Dave’s Garden.
Hens and Chicks
Keep it outdoors as a ground cover, or transfer it inside over winter and take part in the succulent craze.
Vines
Clematis
Perfect for growing over an archway.

Smooth prairie aster
A beautiful perennial that is native to Saskatchewan. It’s one of my favourite flowers to see in the ditches in summer.
Dianthus
Aren’t all these options beautiful? Just because you’re gardening in zone 3 doesn’t mean you can’t have a beautiful garden. I’d love to know which flowers you’ll be planting this year and if there’s any that should be on this list. See you in the comments!
