I hear what you're saying JB. Yes, every definition I have found has to do with tree-forming by cuttings. How in the world it is applied to begonia has baffled me. But I have a lot of cane begonia that I can play with. It might be fun to see if I can strip the leaves and make it umbrella into a tree form, making it branch out at the top and letting the one branch get big and fat forming a begonia tree. I thought maybe someone had some experience with this? Fun.
