Delosperma sphalmanthoides

A tiny tufted ice plant known only from the Roggeveld escarpment near Sutherland in South Africa's Northern Cape, where it forms tight cushions in shallow soil on rock. It is a cold-hardy high-plateau plant, so it wants intense sun, a very gritty shallow mix and cold, frosty winters kept on the dry side.

Where it grows wild

Shallow soil pockets on rock outcrops of the Roggeveld escarpment, a cold, high-plateau part of the succulent Karoo.

No elevations in the records. The Roggeveld escarpment near Sutherland lies at roughly 1,400–1,600 m, so expect a cold, high-altitude climate.
