The Buttonbush, Cephalanthus occidentalis, is a rounded shrub that has a very open, almost gangly, habit of long branches and green foliage.
The foliage emerges in late spring and is one of the latest plants to break dormancy.
The unusual flowers are creamy-white spherical heads, 1 to 1 1/4 inches long, with stamens protruding above the flower head, and blooms in late summer.
The fruit is a nutlet that persists through winter. Birds just love them. Deer and other wildlife feed on the winter twigs.
It prefers moist and boggy soils and and is perfect for naturalizing in wet areas. It is not tolerant of dry conditions. It can be grown in full to part sun. The bright green foliage turns yellow orange in autumn.
Native in the Eastern United States, from New Brunswick to Florida. Its range extends west to Minnesota, Oklahoma and southern New Mexico, Arizona, California, into Mexico and Cuba.
