Definition

Noun: * A genus of South African annual or biennial plants, typically succulent, belonging to the family Aizoaceae. The name is derived from Greek, meaning "midday flower," as the flowers of many species open fully only in bright sunlight.

• In horticulture: "Several species from genus Mesembryanthemum are popular in rock gardens due to their drought tolerance and vibrant flowers."

Advanced Usage
