Aloe dorotheae

A clumping, sprawling Tanzanian aloe with glossy, spotted, recurved leaves that turn strong red to orange-red in drought or full exposure. In the wild it is known from only two rocky outcrops in the Eastern Arc Mountains and is Critically Endangered, but it is common in cultivation. Grow it hot, bright and sharply drained, watering in summer and keeping it drier in winter.

Where it grows wild

Rocky outcrops in the Eastern Arc Mountains, in well-drained, sunny spots. The stems sprawl and the plant forms clumps over time, and it colours up red when stressed or exposed.

No elevation data: the GBIF records carry none, and the source does not give an altitude. The five records cluster at about 5.1–5.5° S, 38.0–38.4° E in north-eastern Tanzania.
