Carpobrotus edulis is a creeping, mat-forming succulent species and member of the Stone Plant family Aizoaceae, one of about 30 species in the genus Carpobrotus. It is also known as ice plant, Highway Ice Plant, Pigface or Hottentot Fig and in South Africa as the Sour Fig (Suurvy; earlier: Hotnosvy), on account of its edible fruit. It was previously classified in genus Mesembryanthemum and is sometimes referred to by this name. The species is native to South Africa but is naturalised in many other regions throughout the world.
