Titanopsis Calcarea, also known as Concrete Leaf Living Stone or Jewel Weed, is a unique mat-forming succulent from South Africa. It has small rosettes of thick fleshy greyish foliage with small warty idioblasts covering the end of the flaring leaf surface. The plant slowly forms a clump and produces a yellow flower. It stays cute and small, making it the perfect lizard-like addition for a container or rock garden, and can even be grown as a houseplant.
