This is one of the most attractive species with dazzling bright silver white succulent leaves that looks sort of like an ice plant but on small, woody stems and the flowers are also nice.
Origin and Habitat: Little Karoo in the Western Cape to the Kei River in the Eastern Cape, South Africa.
Habitat and ecology: This species grows on ledges of sandstone cliffs, on steep slopes of rocky hills, and along dry river valleys in Albany Thicket and Eastern Valley Bushveld biomes, in sandy, mineral poor and acidic soil. The young leaves have a white to silvery felted coating which may be shed as they get older. This felted covering is an adaptation to the dry conditions under which the plant grows and serves to reflect the sunlight, preventing over-heating or burning.
