Crassula minuta

A tiny Crassula described by Tölken in 1975 from the western Cape, known from only a handful of collections, including rock basins on the summit of Tafelberg in the Cederberg and open sandy ground. Almost nothing is published on its ecology; grow it like other dwarf winter-rainfall Crassulas: cool, bright and moist in winter, dry in summer.

Where it grows wild

Specimen labels record rock basins (shallow seasonally wet depressions on sandstone) on a Cederberg summit, open sandy areas and sand dunes. This suggests a very small plant of thin sand in sunny, seasonally moist pockets.

One label gives about 1585 m (Tafelberg, Cederberg); other records are from lower sandy sites, so the range probably spans the lowlands to the high Cederberg.
