The Mountain aloe is one of the single trunked species with gray green leaves featuring darker spines along the edges and the upper and lower leaf surfaces.  The main attraction of course are the reddish orange tubular flowers in graceful spirals on each of the candelabra like flowering stalks that gently curve as they age. Full sun with plenty to room to grow as it reaches mature size. Outdoors it is hardy to about 20 degree F in dry climates.
