Buttonbush info card

Cephalanthus occidentalis, commonly called buttonbush, is a deciduous shrub with an open-rounded habit. The star of this plant is its unusual blooms- globular heads of small white flowers with a pincushion-like appearance appear in early-to-mid summer. Flowers are followed by “button”-like fruits consisting of two-seeded nutlets, which can persist through fall and winter. Flowers are attractive to bees, butterflies, and hummingbirds. Can tolerate flooded conditions, and is a good choice for a rain garden. Buttonbush is a fast-growing shrub that spreads to form thickets by suckering. This plant leafs out later in the spring season has showy fall foliage and is a host plant for 25 species of Lepidoptera
