Lithops is a genus of succulent plants in the ice plant family, Aizoaceae. Members of the genus are native to southern Africa. The name is derived from the Ancient Greek words λίθος, meaning "stone," and ὄψ, meaning "face," referring to the stone-like appearance of the plants.
Lithops are small plants, rarely getting more than an inch (2.5 cm.) above the soil surface and usually with only two leaves. The thick padded leaves resemble the cleft in an animal’s foot or just a pair of green to grayish brown stones clustered together. The plants have no true stem and much of the plant is underground.
Growing living stones in pots is preferred for most but the hottest zones. Lithops need a cactus mix or potting soil with some sand.
The potting media needs to dry before you add moisture and you must place the pot in as bright an area as possible. Place the plant in a southern facing window for optimum light entry.
Lithops care is easy as long as you remember what type of climate the plant originates from and mimic those growing conditions. Be very careful, when growing living stones, not to overwater. These little succulents do not need to be watered in their dormant season, which is fall to spring
