|Vigorous, thinly branched perennial (that you may want to confine) with basal clusters of oblong to lance-shaped, glossy, dark green leaves reaching up to 12 inches long. Leaves have silver marks and wavy margins. Reaches up to 6 feet tall and about 24 inches wide. Spikes of pale pink flowers appear summer to fall. Cut back flower stalks after flowering, leaving foliage. Divide foilage from October to March. Prefers shady situations and occasional deep watering, but tolerates sunny, dry situations too. Its aggressive roots make this plant perfect for slopes. Excellent where coarse texture is needed in the garden.
