Lapidaria is a monotypic genus of dwarf succulent plants in the family Aizoaceae. The only species it contains is Lapidaria margaretae, also known as the Karoo rose.
The lapidaria margaretae is closely related to the Aizoaceae family and resembles succulent plants like Schwantesia and Lithops plants. It is native to areas of South Africa such as southern Namibia around Warmbad and Northern Cape areas and is associated with dry, arid regions which receive minimal to no rainfall throughout the year. Common names of this rare succulent include Karoo Rose, Kangaroo Rose and Mesembs. The leaves of the plant are around 0.8” inches long and 0.4” inches wide and are stone-shaped with short internodes growing in leaf pairs resulting in compact heads. This type of growth is why the plant often called a living stone. They are greyish white or pinkish and the colors become paler towards the base of the leaf paler.
