I had hundreds until this spring when I threw them all away....nobody local wanted the things....go figure!! Anyway, wait until you are nearer the first frost and then just cut them off and dig them up. Put them in peat for the winter in your basement or garage and next spring plant again....they are very, very easy to deal with for the winter, but they multiply way too fast and after 10 years or so you will get tired of planting and digging them. dig and store in peat and you will have them for decades :o) Dan

Thanks, Dan! I'm not so sure I want these for decades! The Cannas were not as nice as I had expected, and while the Glads were really pretty, they didn't last long enough to be worth the effort. I'm glad I don't have very many of either, to be honest, and I'm not sure I'll be getting any new ones come spring again!

The Glads were a mix of the new green flowered and a few whites. The greens were below what I'd consider good performers, and the whites were better, but short-lived.

Thanks for the info!
