Lithops is a genus of succulent plants native to southern Africa with the majority of species found in South Africa. They are in the family, Aizoaceae which is also known by the name Mesembs. Lithops themselves are often referred to as Living Stones. This has probably come about since they do resemble two rocks in a pot. In their native habitat during the dry season they can be almost impossible to find as they look just like the surrounding rocks and pebbles. This adaptation has allowed them to escape the mouths of grazing animals and to conserve moisture. In the natural habitat they receive very little water in the form of rain but daily mist allows them to survive in a very harsh environment.
The genus Lithops comprises of around 35 species but has many hundreds of ssp., hybrids and cultivars. This is increasing every year as growers hybridize and create new varieties. Many of the new varieties have amazing patterns and coloration. Lithops flower have traditionally been white or yellow but in recent years breeding has created white with pink, orange and rose colored flower.
With the sheer number of species, varieties, and coloration Lithops are a collectors dream. These plants are relatively easy in cultivation and once there growing requirements are understood can live for decades creating large clumps.
