Cephalanthus occidentalis (Buttonbush) is a distinctive North American native shrub prized for its unusual spherical flowers, glossy foliage, and exceptional value for pollinators and wildlife. Blooming in summer, Buttonbush produces unique round clusters of fragrant, creamy-white flowers surrounded by prominent stamens, creating a striking display that attracts bees, butterflies, hummingbirds, and other beneficial pollinators.
Its flowers are followed by round fruits that provide additional wildlife value, while its dense branching habit offers cover and habitat for birds and other animals. Cephalanthus occidentalis thrives in moist to wet soils and is an excellent choice for rain gardens, pond edges, wetlands, stream banks, swales, and other areas where moisture-loving native plants are needed.
It can also tolerate occasional flooding, making it particularly valuable for managing wet areas in a naturalistic landscape. With its distinctive summer flowers, attractive form, and strong ecological benefits, Buttonbush is an excellent choice for gardeners looking to create a pollinator-friendly, wildlife-supporting native landscape while adding unique seasonal interest.
