Scientific name

Cephalanthus occidentalis


Buttonbush is a small to medium-sized deciduous shrub species which typically grows about 2 m in height. This plant may also be known by the common name Button Willow. Twigs are slender to stout and dark red-brown in colour with white speckling. The leaves are bright green coloured, shiny, ovate shaped, oppositely arranged, and have entire margins. The flowers are tiny, tubular, white, fragrant, and appear densely on distinctive, spherical clusters in June. These flowers turn into a dense cluster of seeds, which remain on the plant throughout the winter. The flowers are beneficial for pollinator species, including hummingbirds and butterflies. This is a hardy, adaptable species and an excellent choice for planting on wet shoreline sites.

Planting conditions

Buttonbush grows best in moist to wet conditions with full or partial sun exposure. It prefers poorly drained organically rich loam, rock, sand, or humus. It is very tolerant of flooding but intolerant of drought or dry soil. This shrub can be naturally found around wetlands and along river or lake shorelines.
