In Long Beach Calif; there was a Crassula ovata 15' high.
In Africa the trunk is used to bury their dead. I have one 6" around at this time, but it has never been out of it's pot and really has not had the best care, no water during the summer months, no fertilizer, no space to grow any bigger, it's not growing in open run, where it could grow much larger. They will and can grow much larger if given the space to do so, so be careful where you plant this species. It's been there about 15-20 years. Norma

Norma is right - most of us are trying to keep our Jades under control. Around here, you rarely see one that's huge just because few of us have big enough accomodations for them in winter. My biggest ones have about 3" trunks and like Norma, I don't "upsize" them to keep them from getting much bigger. I recently helped a local lady who had some C&S to sell by taking pics of her plants and passing them around to my C&S club members. She had a Jade that was in a 24" or so, stood about 4.5' high and 3' wide. I couldn't even see the main trunk - it was gorgeous! She sold it to one of our club members for $50! What a deal...
