This is a first-rate foliage plant, forming an exotic-looking, upright mound of toothed green maple-shaped leaves. Flowers appear in late summer as tubular sulphur-yellow bells, rising above the leaves on purple-black stems. A good candidate for planting in a cool, damp woodland garden. Plants can be somewhat slow to establish and appreciate a mulch of leaves to keep the soil moist and cool. Beautiful in combination with Hostas, ferns, Astilbe, Toad-lilies and other shade-loving perennials. One of the few late-flowering woodland perennials. Great for cutting. Easily divided in spring, every 4 to 5 years. Cut the dead foliage and stems back to the ground in late autumn. Received a Royal Horticultural Society Award of Garden Merit (1993).
