Delosperma obtusum

A low, mat-forming ice plant from the high grasslands of the eastern Free State and Eastern Cape in South Africa. Unlike most mesembs it comes from a summer-rainfall, frosty climate, so it is one of the more cold-hardy succulents, provided it stays dry in winter.

Record sites at about 1,260 m and 1,980 m; the main cluster is near 2,000 m in the eastern Free State mountains.
