Usually the plants show the deep purplish red colours that you see here, in which case they are easy to recognize, but sometimes the leaves are green or yellowish green, making identification less straightforward.
As a rule the leaves are glabrous, but in the isolated Richtersveld populations they are softly hairy. Most of the populations occur in the mountains bordering the Karoo southwards towards Touwsrivier and Prince Albert, in rock crevices and shallow pockets of soil.
The flowers appear in September and October.
