Cephalanthus occidentalis, commonly known as Buttonbush, is a distinctive native shrub found naturally along streambanks, wetlands, and pond edges throughout much of the United States. It grows 6 to 12 feet tall and wide, forming an open, rounded shape with glossy green leaves and unusual, fragrant, ball-shaped white flowers in summer. These “button” blooms are a magnet for butterflies, bees, and hummingbirds. Buttonbush also produces spherical seed heads that persist into fall and provide food for birds. Thriving in moist to wet soils, this shrub is ideal for rain gardens, wildlife plantings, and shoreline restoration.
