Huge dark green, deeply veined leaves of good substance can measure more than 1½' wide and long. Large leaves are formed as a young plant, though entire clump takes about 5 years growing in the ground to achieve mature size. Strongly upright habit, forming a very tall and wide clump. Pale reddish violet flowers appear just above the foliage in early to midsummer. An outstanding focal point and topic of conversation in your shade garden.
