Cannas in Zone 7
I have never had cannas. At the swap I got some Yellow King Humbert :) I'm very excited about them!
The question is, do I need to lift these in the fall? I know you have to lift the tropical cannas with the variegated foilage, but I also know there are many other cannas that people just leave in. How do you know? Googling reports hardiness of 7 on some sites, 8 on others.
What do you guys do? Does it depend on the particular canna?
Calla lilies are another thing that aren't supposed to be hardy here...but I had a large grouping of them at the other house for ten years that I never touched.
