There are not many of the South African  Aloes that can be grown in Britain. This one is remarkably hardy. Some of it sprawls on the ground and some of it occasionally rears up to 3ft - or more if supported by a wall. Very cold weather will kill off the tips but it recovers. I've had it growing in my West Sussex frost pocket of a garden for many years. Yellow flowers that last for many weeks during the summer. Aloe vera is famous for its effect on burnt skin. You use the sap from a cut leaf to rub on the wound. Does this one have the same effect? Probably.
