Rusty blackhaw viburnum takes its common name from the soft fuzzy reddish covering on its winter buds. This species is native to the southern U.S. White flowers in May are followed by fruit that goes from green to pink to blue and persists into winter. Fall foliage color is deep burgundy. The EMERALD CHARM™ cultivar was selected from the collection of the Morton Arboretum and is reported to be more upright and vigorous than the species.

Viburnums are a versatile genus of multi-stemmed shrubs that are well suited to the home landscape due to their range of sizes and cultural adaptability. Some viburnums are noted for their fragrant flowers; most bear small fruit that may add visual interest. Many viburnums have attractive fall color. There are over 100 different varieties of viburnum at the Chicago Botanic Garden.
