That's how I was. Got one or two a season. But last year I overwintered them and they made it. Alot of mine came from a forum member last year. I bought some at the end of the season and through me in a bunch of little tubers that she found while she was cleaning out.
I would have had more, but I was working so much dh was suppose to be adding water to the lily tank in the little greenhouse and he didn't. Some of them dried out to the point I couldn't bring them back.
This year I have bought 5 and got 6. I've gotta stop, but their so pretty. I'm in love with tropicals. Total I guess I have about 20.
