Aloe harlana

A stemless or short-stemmed aloe from the Harar highlands of eastern Ethiopia, with rosettes of about 24 broad, olive-green leaves up to 50 cm long edged with reddish-brown teeth. Branched inflorescences carry dense racemes of deep red, sometimes yellow, flowers. It grows on stony hillsides in low scrub at 1650–1850 m, so it wants full sun, fast drainage and mild temperatures with cool nights.
