Family:Viburnaceae

Rusty Blackhaw is a shrub or small tree indigenous to the eastern and central regions of the United States, commonly found throughout North Carolina. It can be cultivated either as a shrub or as a tree with multiple or single stems. The plant derives its name from the rusty brown hairs that adorn the undersides of its leaves, buds, and stems. In early spring, it produces clusters of small white flowers, which are followed in the fall by blue drupes. The foliage also showcases vibrant colors in the autumn. To ensure a good yield of berries, it is advisable to plant more than one shrub.

This species thrives in a range of soil types, from dry to moist loams, and prefers full sun to partial shade. It is suitable for use as a hedge, in shrub borders, or in naturalized settings.

Rusty Blackhaw typically inhabits rocky or dry woodlands and forests, as well as areas along streams and valleys.

Fortunately, it does not face significant issues with insects or diseases.
