Do cannas come back every year?
In warm climates (USDA hardiness zones 8 to 10), canna bulbs can be left in the ground over winter, and the plants perform reliably as perennials, coming back year after year.
Can you leave cannas in the ground over winter?
Leaving Canna Lilies In The Ground
Anyone who lives in the warmer zones of 8+ can leave their canna bulbs in the ground over winter, as long as the soil doesn’t freeze. If you live on the cooler side of their hardiness zone, you can mulch them to give them extra warmth.
Where do cannas grow best?
Canna lilies do best in a rich, moisture-retentive soil in full sun or light shade. In the garden they’re perfect for the back or middle of a mixed or tropical border. Some can reach up to 2.5m in height. Even when not in flower, their impressive foliage offers the perfect foil for neighbouring flowers.
