Panicum virgatum ‘Cheyenne Sky' Full sun and well-drained soil 3 feet tall, 18 inches wide 4-9
Actaea simplex (Atropurpurea Group) 'Brunette', bugbane (syn. Cimicifuga). A dramatic, stately perennial, which produces slender, bottlebrush-like, pale pinkish-white flowers in September and October above clumps of three-lobed, deep purple leaves. Its a useful plant, both because it comes into its own late in the season, when many flowers have finished, and because it thrives in damp shade. Try it at the back of a border, between evergreens.
