1" x 6" wide, (seed propagated). This species is the most cold hardy in this genus of South African succulents closely related to Aloinopsis. Titanopsis needs a fast draining rock garden soil, with the roots situated so they grow down 4-6" or more between closely spaced rocks into the subsoil. (Open soil beds with no rocks hold too much moisture around the roots in winter and can cause the roots to rot.) The fabulous succulent leaves of this plant are gray and warted, closely resembling the rock strewn ground of its native habitat. Large shiny yellow flowers appear in early spring. Zones 5-9. 3" deep Standard pot.
