Description
It is a thinly branched perennial with basal clusters of oblong to lance-shaped glossy, dark green leaves reaching up to 12 inches (30 cm) long. The base of the stem is woody, and the nodes of the stem are hairy. The leaves have silver marks, wavy margins and thorns. It reaches up to 6 feet (1.8 m) tall and about 24 inches (61 cm) wide. Spikes of pale pink flowers appear summer to fall. In cultivation it prefers shady situations and occasional deep watering, but tolerates sunny, dry situations too. Its aggressive roots make this plant well suited to slopes.
