|Evergreen succulent with a mat forming growth habit, that bears rosettes of pointed, thick leaves, many times with bristly margins, or covered with a web of white hair. Nigrum has medium green, red-tipped leaves. Star-shaped, reddish-purple flowers are held in flat cymes on the terminal ends of hairy, upright stems. The rosettes die after flowering but are replaced by new rosettes on lateral runners. An old time favorite used in concrete planters on either side of the front entry. Great in window boxes or niches.
