Cephalanthus occidentalis, commonly known as buttonbush, is a distinctive deciduous shrub valued for its unusual, spherical flowers and suitability for damp conditions. In early to mid-summer, it produces perfectly rounded balls of creamy white blooms made up of protruding pin-like stamens, giving the plant a bold, architectural look. The flowers are rich in nectar and highly attractive to bees and other pollinators. Fresh green leaves form a dense framework through the growing season, turning soft yellow in autumn. Naturally at home near ponds, streams, and wet ground, it also performs well in moisture-retentive borders, making it an excellent choice for wildlife-friendly gardens.
