Crassula cotyledonis

A low, short-stemmed South African Crassula with rosettes of grey-green, velvety leaves covered in fine backward-pointing hairs. It grows on hilltops, slopes and rocky outcrops from the Worcester area through the Karoo to the Eastern Cape and north into Namibia, so it wants full sun, very sharp drainage and a clear dry season.

Where it grows wild

Rocky hilltops, slopes and outcrops in very stony ground, from fynbos margins in the Western Cape into the Karoo. Plants sit wedged among rocks in thin mineral soil, fully exposed to sun and wind.

No elevation figures in the sources opened; the range covers lowland Karoo plains to mountain slopes, so plants meet both hot summers and frosty winter nights.
