Conophytum is a genus of South African and Namibian succulent plants that belong to the family Aizoaceae. The name is derived from the Latin conus and Greek phytum. The plants are also known as knopies, waterblasies, sphaeroids, conos, cone plants, dumplings, or button plants. They are well adapted to pot culture and are quite happy on a sunny windowsill. In their distribution range they do well in rockeries. Next to Lithops, Conophytum is the most popular genus of the Mesembs.

Conophytum mirabile is known from just one quartzite hill, hence the vagueness of the locality. It was originally discovered in the 1980s but not brought into cultivation until rediscovered in 1999. Out of flower, the hairy bodies could easily be confused with Conophytum stephanii, but the large day-opening flowers are quite different.
