|Vigorous perennial (that you may want to confine)
with basal clusters of oblong to oval dark green leaves reaching 24 to 36 inches long. Deeply cut lobes are narrow at the base of the leaf and have wide midribs between the lobes. Reaches 24 to 48 inches tall and about 24 to 36 inches wide. Spikes of white to pale pink flowers with light purple bracts appear in 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 garden. Sometimes referred to as Acanthus balcanicus or Acanthus longifolius.
