Crassula sericea

A small succulent Crassula of Namaqualand, the Richtersveld and southern Namibia, named for its silky hairs (sericea means silky). It comes from one of the driest parts of the winter-rainfall succulent Karoo, so it needs full sun, a very mineral mix and careful, mostly cool-season watering.

Where it grows wild

Rocky slopes and gravel plains in succulent Karoo, in full sun, often in rock crevices or among stones. Detailed habitat notes on records are sparse, so this is inferred from the localities.

Records carry few elevations; the localities lie roughly between 100 and 1200 m.
