Sinocrassula yunnanensis --Black Sea Urchin--

Densely stacked pointy, rough green leaves in a beautiful fractal spiral. Full sun to part shade. Let dry between waterings. Leaves deepen to black in direct sun. It grows as a dense, compact rosette and crests more often than other succulents. Each rosette blooms once in its life and is then replaced by new offsets. With time, it can develop into an impressive clump. Slightly finicky grower, can't tolerate a freeze and really wants well drained and almost dry soil.
