Lynn,
The Cannas go dormant but I sprinkle water on the pots about three times during the winter. I try to keep my Tropicals half alive and half asleep because my summers are so short I like them ready to go as soon as the weather warms up.
I know a lot of people put them in brown paper bags after the Fall weather kills the leaves and store them in a cool corner. If I did that my plants would not start growing good until late June and would not have the tall leaves until late July. I would only have pretty leaves August and half of Sept before I would have to start thinking of winter.
You zone they might even be hardy for you. My sister is in Atlanta and the one with purple leaves are hardy for her.
You can do what fits you needs. I know I will not dig up a plant or bulb so growing in pots and just bringing in just the pot is easy for me.
If you want to try T-mail me.
