Pot size recommendations?
A friend gave me some canna tubers and I'd like plant them in a pot that I can bring inside for the winter. I've never grown cannas and am not sure which canna I have. The plants she has are 3-4" tall, plain green leaves and red flowers (that description probably does not narrow it down!)
My question is what is best sized pot for these? I'd love a manageable enough size to lug down to the basement without help. How much room do they need for their roots?
