Description

Buttonbush is a multi-stemmed native shrub with glossy green leaves and distinctive spherical clusters of white flowers that bloom in summer. These unique flower heads are highly attractive to pollinators and beneficial insects.

The shrub provides important nectar resources while also offering shelter and habitat for wildlife.
