Crassula tomentosa

A rosette-forming Crassula from the arid winter-rainfall west of South Africa and southern Namibia, with thick leaves covered in dense hairs. The rosettes produce a tall inflorescence and in many forms die after flowering, so offsets or seed carry the plant on. It needs strong sun, a cool, wet winter and a hot, dry summer.

Where it grows wild

It grows on open, rocky, stony slopes and flats in succulent Karoo and dry fynbos vegetation, fully exposed to the sun. The hairy leaves protect it against sun and drying out.

Few records carry an elevation. The measured sites are inland, where summers are hot.
