Aloe pearsonii
A clumping, stem-forming aloe from the arid Richtersveld mountains on the South Africa–Namibia border, with erect stems clothed in four neat rows of thick, recurved leaves. It is said to be the slowest-growing of all aloes, and wild clumps over 2 m tall may be several hundred years old. Grow it hot, very bright and mostly dry, watering mainly in the cool season as its winter-rainfall home does.
Where it grows wild
Grows in groups in sandy patches among rocks on the Richtersveld mountains, one of the driest parts of southern Africa. Rain is scarce and falls mostly in winter, and plants are thought to take up moisture from mists that drift over the slopes. Leaves turn red in dry spells and fatten to blue-green after rain.
The records carry almost no elevations. The Richtersveld mountains where it grows rise to over 1,000 m; treat any elevation as an estimate.
