Buttonbush, Cephalanthus occidentalis
 
Buttonbush is a fast-growing shrub that can reach 3 m in height. Its very unusual, beautiful white globular flowers bloom in August and fill the air with a honey fragrance. After flowering, the flowers still look attractive by turning first red and then dark brown.

Bees and butterflies enjoy its nectar, and mainly water birds its seeds. It is the host plant for many moth species.
 
Growing conditions:
Buttonbush likes moist and wet soil. It thrives in full and partial sun and in any soil, even compacted soil. An ideal location is close to the downspout, in a rain garden, or at the edge of a pond.
