Aloe petricola

A stemless or short-stemmed aloe from rocky granite and gneiss outcrops in the Mbombela (Nelspruit) to Barberton area of Mpumalanga, South Africa. It forms clumps of grey-green rosettes and puts up tall red-and-cream flower spikes in winter. Grow it hot, bright and dry in winter, with water in the warm season, as for other summer-rainfall aloes.

Where it grows wild

Grows on rock sheets and among boulders in grassland and open bushveld, rooted in thin, gritty soil pockets between stones. The name means 'rock-dwelling'. Plants sit in full sun with little shade around them.

The records carry almost no elevations. The mapped sites lie in the Mbombela–Barberton hills, which are mostly around 600–1,500 m; treat this as an estimate.
