Mesembryanthemum tomentosum

A small succulent of the ice-plant family from the extremely arid lower Orange River area, along the border of South Africa's Richtersveld and southern Namibia. It lives with very high light, hot summers and almost no rain, so it needs full sun, a lean mineral mix and very careful watering. Species-specific information is scarce; this profile relies on the genus and the measured climate.
