I've grown caladiums before, so they can take the heat. (They were from Happiness Farms in Florida.) I've never had them return for a second year, even when I dug up the corms and kept them indoors. That's cool that you won a raffle. I haven't attempted because I don't have room for much of anything new. I do have a pot in which I'd like to put an Echinacea but I'll wait until spring to get one.
