Actually, being the dummy I am sometimes, I didn't winter over this particular plant, but Carrie and Charlie did, out in the regular flower bed that has a little shelter, not much, with no cover, so I know it will work here, too. Actuyally (blush, giggle) mine DID come bck, but I thought it was something else, so I yanked it out....oops! She just lets her's die back and then trims it for looks, and waits for the spring to kick in. This one has lots of seeds, so I'll try to collect some and send them as they mature. So that brings me to wonder this: Is the plant itself coming back, as a half hardy annual, or is it re-seeding? HMMMM
