Delosperma

Delosperma is a genus of around 170 species of succulent plants, formerly included in Mesembryanthemum in the family Aizoaceae. It was defined by English botanist N. E. Brown in 1925. The genus is common in southern and eastern Africa.

Plants of the genus Delosperma can be distinguished by their seed capsules. When these open (in response to rain), the seeds are exposed and not covered by a protective membrane, like those of most other plants in the family. The membrane is sometimes reduced to just a ledge (a feature shared by the related genus Trichodiadema). The triangular valves, which open outwards when wet, each have distinctive wings on either side.

Flowering times are from August to January, depending on rainfall. The plants often flower sporadically throughout the season if rainfall persists.
