Fruits 1⁄3 in. long, oval, blue-black.
Native of eastern N. America; introduced in 1752. This viburnum is closely akin to V. cassinoides, under which species the distinctions between the two are explained. It is a handsome, shiny-leaved shrub which flowers freely. It has a more southern distribution than V. cassinoides, and does not, apparently, reach into Canada.
