I have planted my cannas like Sue and Reddad. Both ways did well. Since I'm a lazy ponder I pack the bareroots into a plastic water plant colander basket and tie it down in the shallow end of the pond. Couldn't find shots of the potted cannas like this but know they grew tall and flowered like crazy. I recently rearranged the plants in this pond and wintered the cannas in a 25 gallon bucket with just the rain water it receives during the winter (and last week!)
