A very hardy Aloe species if given a sharply drained soil and our parent/ stock plants have now done several winters outside in West Sussex. Cold does not seem to be a problem for this stunning succulent but excess winter wet is so plant on a well drained bank/ rockery, in a wall or if growing in a pot turn it on it's side for the winter, just make sure that excess winter rain does not sit in the crown.
Haworthia-like rosettes of stiff green leaves create a gorgeous 15cm tall mound up to 40cm in diameter. 60cm tall spikes of attractive orange flowers often appear during the summer. The sap in the leaves is said to have similar properties to Aloe vera and I have to say it certainly does feel soothing on sore skin areas.
