Aloe comptonii

A sprawling, rock-dwelling aloe of the Little Karoo and adjacent mountains of the Western and Eastern Cape, with blue-green, toothed leaves and red flowers. It lives in hot, dry summers and cool winters with light rain spread through the year, so it wants full sun, a very sharp mix and no hard frost.

Where it grows wild

Rocky, steep slopes and cliffs in Karoo scrub (succulent karoo and fynbos margins), often hanging from rock faces with decumbent stems.
