Cotyledon
Also called Pig's Ears
Cotyledon is a genus of succulent shrublets in the Crassulaceae family, mostly from southern Africa. Commonly grown members, such as the pig's ear (Cotyledon orbiculata), need bright light, sharp drainage and sparing water.
Cotyledon is one of some 35 genera of succulent plants in the family Crassulaceae. Mostly from Southern Africa, they also occur throughout the drier parts of Africa as far north as the Arabian Peninsula. Ten of its species are mostly confined to South Africa, where unlike Tylecodon, they occur commonly in both the winter and summer rainfall regions. They may be found on coastal flats and rocky hillsides, or as cremnophytes on cliff faces. Their decussate, evergreen leaves are highly variable in shape, even within some species, but the flowers, apart from colour, are very similar.
Most plants in the genus, and those that used to be included in the genus Cotyledon, are poisonous, even dangerously so. Some have been implicated in stock losses among goats, pigs and poultry. However, many species have long been used in traditional medicine. They have been applied for many purposes, ranging from magic charms to removal of corns.
Cotyledon species are grown as garden and indoor subjects, practically independent of irrigation in all but full desert conditions, though they cannot survive poor light or bad drainage. Pests that affect them include sucking bugs, members of the suborder Auchenorrhyncha such as the mealy bug (Pseudococcus), and similar insects. The inflorescences of the larger species are sometimes used as components of dried arrangements in floral design.
