There are 14 species of densely clump forming rhizomatous perennials, in this genus. \u00a0They occur from moist Mountain Ravines, woodlands, and stream banks in Southeastern Asia and only 2 species are from North America. \u00a0Grown for their striking plume like panicles that rise above the foliage, that\u2019s 7-30\u201d long consist of tiny red pink, purple, or white flowers borne in early and late summer. \u00a0\u00a0They produce basal tufts, of 2 or 3 ternate leaves each with leaflets further divided into 3-5 sharply toothed lobes ranging in height from 5\u201d-4 \u00bd\u2019 feet high. \u00a0The flowers when dry or fades will take on decorative shades of brown, which can be persistent well into winter. \u00a0They will thrive in a damp border or a woodland garden or for waterside plantings or in a shady rock garden.<\/p>\n
