Found mostly in Namibia and South Africa, they are members of the ice plant family. They avoid being eaten by blending in with surrounding rocks and are often known as pebble plants or living stones. Because their camouflage is so effective, new species continue to be discovered, sometimes in remote regions of Namibia and South Africa, and sometimes in well-populated areas where they simply had been overlooked for generations. So far, nearly a thousand individual populations are documented, each covering just a small area of dry grassland, veld, or bare rocky ground. Lithops are popular house plants and many specialist succulent growers maintain collections. Seeds and plants are widely available in shops and over the Internet. They are relatively easy to grow if given sufficient sun and a suitable well-drained soil.
