Re: One for the green Thumbs - plants, cold hardy?
Off the top I'd say give "winter petunias" a shot. I don't normally put them in pots but have a few times placed in window boxes. And they did okay there though not as well as in the ground. Could be that I don't water in the winter so most likely didn't water them until they showed distress.
They are on the less expensive side - so if it doesn't work out you haven't spent a whole lot.
