Cephalanthus occidentalis

Buttonbush (Cephalanthus occidentalis) is a deciduous shrub native to wetlands and stream banks across North America. It typically grows 6 to 12 feet tall and wide, forming a rounded, multi-stemmed habit. Buttonbush thrives in full sun to partial shade and prefers moist to wet soils, tolerating periodic flooding and standing water. Its distinctive spherical flower clusters bloom in summer, attracting pollinators like bees and butterflies. This shrub is ideal for rain gardens, pond edges, and other wetland plantings, providing both ornamental value and important wildlife habitat.
