The genus Pleiosopilos occurs in various parts of South Africa, straddling the Easter and Western Cape provinces, in the Northern Cape Province, and in the Free State. The plants are characterized by their highly succulent, rock-like leaves that are heavily dotted. P nelii, perhaps the most common member of the genus in cultivation, blooms in the winter, while all other species flower in the autumn. The plants are active in the summer and should be kept dry in the winter, except the popular P. nelli, which requires water throughout the winter if it is to do well. They are ideal pot subjects and require a sunny window, but can burn if care is not taken. They are susceptible to red spider mites.
