|Vigorous perennial (that you may want to confine) with basal clusters of large, shiny, deeply lobed, dark green leaves. Spikes of white to light lavender flowers appear from late spring to early summer. 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 gardens.
