Cannas in Zone 7

17 years ago

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.

I have had cannas in my yard for over 15 years now and NEVER dug them up. They just keep comming up thicker each year!

I have the Yellow King Humbert, never dug up, no problems here. I am about as far into west tn. as you can go without jumping in the river.
