Well, because of it's nature, it won't ever look like... a maple tree in the same sense of being a tree, but if you take care of it properly, and go to this website - www.bonsai-bci.com/species/adenium.html for general information, you should be able to eventually make it look less like a potato and more like a tree. Certainly you can enjoy the flowers!

Joe:

There is a page or two on Adenium in:

"BONSAI IN YOUR HOME An Indoor Grower's Guide" by Paul Lesniewicz

I have been looking for information to train an Adenium too.

So I want to cut my adenium plants to promote more branching, I've owned them for about two summers, they haven't done much, how should I go about it?
