Anyone know of a cultivar hardy to zone 6? I dont want to have to cater a microenvironment for them on my family farm since I will have them out in the open. I am in zone 7a and if they are hardy to zone 6 they'll survive here fine without help. Anyone know? I was told they have an excellent tuber for eating.

I don't know of a variety that is hardy to Zone 6. Most of the information that I have seen says that the canna are dug up then replant in the spring.

Since you are Zone 7a, have you tried growing them all year without digging?
