Description:

Common Buttonbush’s fragrant, white, spherical-shaped flowers resemble pin cushions. The flowers bloom in June, followed by round, button-like fruits enclosing small nutlets, which persist into winter. The flowers provide a nectar source for native bees and butterflies. Buttonbush is a host plant for butterfly and moth larvae (caterpillars), including Titan sphinx (Aellopos titan) and Hydrangea sphinx (Darapsa versicolor). It prefers moist to wet conditions, and can tolerate flooding. The plants can be pruned or cut to the ground in early spring. Use Buttonbush in shrub borders, woodland gardens, rain gardens, and other moist areas of the yard, or plant along edges of ponds and other water features.
