Arrowwood viburnum is a lovely but critically imperiled Missouri shrub, but the white flower clusters and dark blue berries make it a great choice for landscaping.

Gray dogwood is a deciduous, thicket-forming shrub. Its small, creamy-white flowers occur in branched clusters, and its white or pale blue fruits are supported by red stalks — a characteristic that makes it attractive for ornamental uses.

Rough-leaved dogwood is one of Missouri's hardiest shrubs, capable of withstanding cold and drought. The leaves of this thicket-forming species emit a faint odor of sour milk.
