Crassula subaphylla

A small, wiry Karoo shrublet 15–30 cm tall, with brittle branches, flaking bark and scattered narrow leaves that drop easily, leaving the plant almost leafless ('subaphylla'). It is widespread in the Succulent and Nama Karoo of South Africa and southern Namibia. It wants full sun, a very mineral mix and restrained watering, with a clear seasonal rhythm.

Where it grows wild

Stony karroid flats, slopes and rocky mountain ground in the Succulent Karoo and Nama Karoo, including the Little and Great Karoo, the Overberg, Namaqualand and the Worcester–Robertson valley. It grows among other dwarf shrubs on shallow, stony, well-drained soils.

It ranges from lowland karoo to mountain slopes. Few records carry an elevation, so this was not measured.
