plant sale text: Common buttonbush is a southeastern native shrub that is easy to grow and an excellent choice for naturalizing. Interesting globular heads of creamy-white flowers are a preferred nectar source for ruby-throated hummingbirds. The sweetly fragrant flower heads persist for several months. A single shrub will spread at a moderate rate into a handsome thicket. This species is easy to grow although it is infrequently offered for sale. Attractive to pollinators. The genus Cephalanthus supports up to 19 species of lepidoptera. 2023 N.C. Wildflower of the Year
