Dig the tubers up, wash them, sprinkle them with sulfur powder, and wrap them in burlap or saran wrap. Plant them after danger of frost.

Canna lilies are perennial plants, meaning they can grow year after year in suitable climates. In USDA hardiness zones 7-10, they can survive the winter outdoors. In colder regions, the rhizomes can be dug up and stored indoors during the winter to ensure they grow again in the spring. Proper care and conditions will ensure they thrive annually.
There are so many varieties, it makes a direct answer difficult. There are daylillies, canna lillies, calli lillies, spider lillies and many many more. Of these listed, daylillies can be the size of a coffee cup, up to 4 feet tall and 2-4 feet in diameter (in groups). Cannas grow from 6 inches tall to almost 7 feet tall.
