Growing Cannas and Callas Up North
Here in the North, we can grow daylilies to our hearts’ content. They’re hardy and reliable and we can count on them even when winters are frigid and spring is slow to come. But even though we’re devoted to daylilies, sometimes we can’t help it if another plant catches our fancy, like the flamboyant canna lily and its understated cousin, the calla lily. Can we grow cannas and callas in the North and add those colorful blooms to our gardens? Yes, we can!
Here’s a horticultural secret (okay, maybe not all that secret)… Cannas and callas aren’t actually lilies. And, unlike our trusty, cold-hardy daylilies, cannas and callas are quite the opposite—not cold hardy at all. That doesn’t mean we can’t grow these eye-catching beauties, it just takes a bit of knowledge.
Success with cannas and callas
Luckily for us, the basics of growing cannas and callas are similar, so you’ll able to grow both once you master the steps. Both cannas and callas grow on rhizomes, and because they aren’t hardy in our region, you’ll need to overwinter them indoors. This requires cutting back the plants in the fall and digging up the rhizomes for indoor storage. (A cool, dry place is ideal—just don’t let them freeze.) When spring comes and the danger of frost is past, you can return the rhizomes to your garden and plant them approximately 5 inches deep and 8 inches apart. If you want, you can start them in pots before transplanting or you can wait to plant in the garden once the temperatures are sufficiently warm.
Here’s a key tip: both cannas and callas love the sun. In order to thrive and produce the best blooms, they need access to full sun. (Callas are small enough to grow indoors, but if you do, just remember that they’ll need to be in a spot soaked in sunshine.)
But there’s more to growing cannas and callas than just making sure they have sun. They’re also particular about their soil conditions. They like rich soil that’s kept nicely moist, so water regularly to keep them happy.
Cannas or callas? Or both?
If you like eye-catching, show-stopping flowers that demand attention in the garden, then you’ll gravitate to the cannas. They have the size (they can reach 6 feet tall!) and a vibrant range of colors that definitely make a statement in the garden.
On the other hand, if you prefer plants that are more compact and not quite as gregarious, callas might be your best bet. While they are found in a variety of colors, the blooms are commonly white. They’re much smaller than cannas and are more at home in containers, so if space is a consideration, choose callas. Important note: callas are considered poisonous to pets. On a brighter note, callas are extremely pollinator friendly, so if you’re looking to attract pollinators to your garden, including callas is a smart choice.
Cannas and callas make a glorious addition to any garden, even here in the North. You, too, can enjoy these beautiful plants in your garden. Have fun!

I grew cannas in my yard several years ago. I gave up (although I did use a few as container plants one year), since I do not have a cool place to overwinter the rhizomes.
We’ve been growing cannas in our Minneapolis yard since 1978.
One fun idea that has worked out is to grow some dark red ones in a big
black 3 foot high tub, and then surround the tub with green cannas. I use
hose-end MiracleGro, especially on the ones in the tub. This makes it look
like the center ones are eight feet tall, surrounded by five-footers.
I HAVE heard of some people planting flowers like callas (and dahlias) as annuals.
A “bit” more expensive than some other annuals, but maybe worth it.
My daughter and granddaughter gave me 4 calla lily bulbs several years ago and I have been storing them each winter and starting them in the house and planting outside in the summer and having success. I have more than 4 bulbs now.
I love cannas and callas… I have earned the name ” The Canna Queen” …at least that is what I call myself. Every year I dig up these gigantic rhizomes and store them until spring when I gift them to many of my gardening friends and unsuspecting strangers who plant them and then realize how tall they get. One of these, told me that during COVID, these cannas provided her respite as a jungle in her tiny backyard, and she would hide in their shade. I have about 300 stored in my garage and hope to spread the joy this next spring.
I got 6 Red Canna lily bulbs (Robert Kemp) from a friend gardener and after 2 years I have over 20 and giving them away – spread the joy! I planted some inside pots, 5″ down on Jan. 27th (soaked the nite before) and now March 25th they just popped out – I hope I can plant them outside in May? Weather in St Criox Cty, WI = 60F, from mid Jan. into March! Snowed only 2 times since Dec. 23
Can they be grown in pots and overwintered in those pots in an unheated greenhouse or must they be stored un-potted?Thanks for your reply
