Multi-stemmed shrub with pointed blade-like leaves that occur in pairs or in threes. 

In late summer tiny white to pale pink flowers bloom in dense spherical clusters with a fringe of yellow pistils, resembling a pin cushion.

Brown masses of seeds remain through the winter.

The seeds become food for ducks and other waterbirds, and the flower’s nectar is of special value to native bees, honey bees and bumble bees and also attracts butterflies.

Grows in swamps, prairie swales and marshes and prefers moist soil and partial shade.

New York native.
