HORTICULTURAL
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.
