While North American native viburnums occur most commonly in the eastern United States, rusty blackhaw viburnum flirts with the edge of the Plains. One of the most drought-tolerant species in the genus, rusty blackhaw viburnum has neither the showiest floral display nor heaviest fruit production. Still, its glossy, dark green, leathery foliage is reason enough to grow it; the rich burgundy tones of its fall foliage are icing on the cake.

A familiar native shrub, American elderberry is commonly seen along streambanks and roadsides and in moist woodlands and thickets throughout eastern North America. It has pinnate leaves with toothed leaflets and small white flowers borne in large flattened clusters in summer. Purple-black, round fruit comes next, attracting wildlife to the garden. Elderberries typically grow to about 12 feet high, but they tolerate pruning to a smaller size. Fruit is edible when cooked.
