Aloe reitzii

Aloe reitzii is a mostly stemless South African grassland aloe with a single dense rosette of waxy, sea-green leaves and cylindrical spikes of red flowers that are yellow on the underside. Var. reitzii grows on rocky slopes at 1,200–1,600 m in Mpumalanga, and the smaller var. vernalis on granite slopes in northern KwaZulu-Natal. It needs full sun, very free drainage, summer watering and a dry, cool winter, and it tolerates light frost.

Where it grows wild

Rocky grassland slopes: var. reitzii in the Tonteldoos valley between Roossenekal and Dullstroom, and var. vernalis on steep, well-drained granite slopes between Vryheid and Natal Spa. Plants grow in full sun among grasses and rocks.

Var. reitzii grows at about 1,200–1,600 m on the Mpumalanga highveld escarpment; var. vernalis at similar mid elevations in northern KwaZulu-Natal.
