- Description
-
Rusty blackhaw is a deciduous multi-stemmed shrub or small single-stemmed treein the Viburnaceae (haw) family. It is native to eastern and central USA and is found in most areas of NC growing in rocky or dry woodlands and forests, along streams and valleys. The name comes from the rusty brown hairs on the undersides of leaves, buds and stems.
Rusty blackhaw grows in dry to moist loams in full sun to partial shade slowly reaching a height and width of 10 to 20 feet. Clusters of small, white flowers mature in early spring followed by a blue drupe that matures in fall. The leaves have excellent fall color. More than one shrub is needed for good fruit production. This low maintenance plant is resistant to browsing by deer and is drought tolerant once established.
Use this native plant as a hedge, in shrub borders and naturalized areas. This plant provides nectar to pollinators, fruit for birds, and small animals making it an excellent choice for a pollinator or wildlife garden. Its low flammability rating makes it a good choice to plant in the defensible space around a home.
Insects, Diseases, and Other Plant Problems: No serious insect or disease problems.
