Cephalanthus occidentalis – The Buttonbush
Cephalanthus occidentalis, commonly known as Buttonbush, is an unusual and eye-catching deciduous shrub that thrives in damp or wet ground. Native to North America, it is perfect for adding a touch of the exotic to wildlife-friendly and waterside gardens.
In midsummer, rounded flower heads resembling tiny pincushions or satellites appear in abundance. These creamy-white globes are rich in nectar, attracting bees, butterflies, and other pollinators in large numbers. As the blooms fade, they are followed by decorative seed heads that persist into autumn, adding continued interest.
The glossy, dark green leaves form a dense, attractive backdrop throughout summer, before turning warm yellow in autumn. With its tolerance for heavy soils and seasonal flooding, Cephalanthus occidentalis is a superb choice for pond margins, streamsides, or low-lying garden areas where many other shrubs would struggle.
