Hi, I have no idea myself, though it seems like an interesting idea, but there was a thread recently on BonsaiTalk.com and I think if you post there, you might get some answers, though of course others here may have some too.

If it's an actual olive - Olea - then it needs to be outside.

It's probably a Bucida spinosa, but if that's wrong, listen to Josh!

Ah, is that the other 'Black Olive' that I hear folks talk about from time to time...? Off to google...

Aha! I see what it is now. Well, Steamer, if you're already in Florida (which some believe is this plant's native habitat), then I'd still suggest you grow it outside. Most websites suggest it not be exposed to temps below 40°F for best result....so there are probably a few nights out of the year that you'd actually have to cover the tree or bring it inside.

Listen to Lucy ;)
