Buttonbush

Common Buttonbush

The Buttonbush (Cephalanthus occidentalis) is a stunning native shrub beloved for its distinctive, globe-shaped white flower clusters that bloom in summer. Each flower head resembles a pin cushion, attracting butterflies, bees, and hummingbirds with its sweet nectar. Growing 5–12 feet tall, Buttonbush is perfect for naturalized areas, rain gardens, and pond edges, where it thrives in consistently moist to wet soils.

A member of the coffee family, Buttonbush adds texture and visual interest with its glossy green foliage that turns yellow in fall. Its unique flowers mature into attractive, button-like seed balls that persist into winter, providing food for birds and seasonal interest. Buttonbush not only beautifies the landscape but also supports local ecosystems by offering valuable habitat and nourishment for pollinators and wildlife.
