Thanks Ric. The C. esculenta does fine in boxes with the callas. I'll try potting up some of the others in the fall and see how that goes. They're all in ground right now. I'll have to see how the Spanish market varieties work out. Two types are putting up larger leaves now.
Is your GH heated? I've been wanting to try some Alocasia and have plenty of room to toss them on the floor.
