Sedum furfuraceum Family: Crassulaceae. An attractive compact species with fat, rounded leaves look like little jellybeans. High light will give you red to purple leaves while lower light will cause the leaves to turn green. The leaves also develop a white coating or frosting that gives it a unique appearance. Easy to grow, just avoid overwatering. Protect from hot afternoon sun and freezing temps.
Please note that the white coating you see in the pictures is normal and characteristic of the plant. It isn't hard water!
