Mesembryanthemum

Mesembryanthemum (meaning "midday flowering") is a genus of plants native to southern Africa. Many species which were formerly placed herein have since been moved into other genera such as Carpobrotus and Delosperma. Sceletium is sometimes included here.Fig marigold or Icicle plant is a name for any of several South African taxa of Mesembryanthemum which are cultivated as ornamental plants for their showy pink or white flowers. "Pebble plant" or "Ice plant" are other but rather ambiguous common names, usually referring to other Aizoaceae. Mesembryanthemum is a member of the family Aizoaceae; many members of this family including the present genus are characterized by long lasting flower heads. Flowers of Mesembryanthemum protect their gametes from night-time dews or frosts but open in sunlight. There is obviously the evolutionary advantage of doing this; where sun, dew, frost, wind or predators are likely to damage exposed reproductive organs, closing may be advantageous during times when flowers are unlikely to attract pollinators.
