What do cannas do in the deep south? Do they keep growing and blooming all winter? If so, could I bring a potted canna into the basement, in my daylight window, and keep them growing all winter? The window stays over 55 and gets good light, and water if I think of it. (A daylight window is basically a concrete greenhouse with windows only on the top. Mine sticks out of the ground 2 ft, so there is good sunlight on the sides on that top part. It's 10' deep, with 8' underground, hope that makes sense)
Cannas will overwinter outside here most winters. Last winter a forgotten group even survived in a pot. Now that Rick has jinxed us, I guess I'll be carrying those pots down to the basement. Or is it better to bare root them for storage, or can I keep growing them?
