Blackhaw is a large, suckering, native shrub or small tree in the muskroot family that matures at a slow rate to 15 feet tall and nearly as wide. It provides 3 seasons of interest and is a high-value wildlife plant. The spring flowers are in large white cymes and the fall leaf color is in reds and purples. Berries mature to purplish-black and are eaten by both humans and birds. Viburnums set fruit better with more than one shrub for pollination. The genus name comes from the Latin name of a species plant. The species name refers to the similarity of the leaves to the Black Cherry (Prunus). The common name comes from this plant’s similar appearance to hawthorns. Blackhaw prefers full sun or partial shade and medium to dry moisture in well-drained soils. It will grow in deep shade but will rarely bloom without sun. It is a hardy plant, adaptable to various soil types and pHs, tolerates cold winters and periods of drought. Because buds for next year’s blossoms form in the preceding summer, any pruning should be done immediately after flowering.

This is a great shrub for naturalized areas or can be used as a hedge or specimen. Blackhaw does well in urban conditions and can be pruned to a tree form. While typically rounded, lighting conditions can cause irregular growth. The root system is a branching woody taproot. Unlike some species of Viburnum, the Blackhaw trunk is crooked with spreading branches and the fragrance of its flowers is sweet and

pleasant.
