Judy, we already went public a couple of weeks ago, and nothing terrible seems to have happened. If anything does, I have my handy ban button ready to push.
I received an e-mail from Bert Bleek today or yesterday about a Caladium co-op. He's a member of our rose cubit, so I hope he'll post something about it here in the Companion Plants Forum.
In the meantime, go to this link, create a username for the co-op login, and take a look at the caladiums he's offering. You won't see the Caladium page until you've logged in as a co-op member. There's no obligation to buy just because you're a member, but I've bought lots of bulbs and daylilies from him in the past and I've always been happy with them.
