Viburnum trilobum

Viburnum trilobum (American cranberrybush viburnum, American cranberrybush, kalyna or highbush or high bush cranberry) is a species of Viburnum native to northern North America, from Newfoundland west to British Columbia, south to Washington state and east to northern Virginia. It is very closely related to the European and Asian Viburnum opulus, and is often treated as a variety of it, as Viburnum opulus L. var. americanum Ait., or as a subspecies, Viburnum opulus subsp. trilobum (Marshall) Clausen.
