clump forming plant that grows to 1.5 – 2.4 meters (5 – 8 feet) tall and about 1.2 meters (4 ft) wide. Plants are found in full sun to part shade in moisture retentive to wet soils.Stem s are upright, thick, round, and purple, with whorls of leaves at each node. As the plant begins to bloom the stems often bend downward under the weight of the flowers. The leaves grow to 30 cm (12 in) long and have a somewhat wrinkled texture. The purpleish colored flowers are produced in large loose, convex shaped compound corymbiform arrays. Plants bloom mid to late summer and attract a lot of activity from insects that feed on the nector produced by the flowers. This species hybridizes readily with other species of "Eutrochium " and where this species and those species overlap in distribution the resulting plants can be difficult to resolve to a specifictaxon .
