Field Guide

Osage orange is a densely branched, short-trunked, thorny tree. It bears weird-loooking, softball-sized, chartreuse, brainlike fruits, which often lie beneath the tree in abundance in autumn.

Introduced from Asia as a groundcover, wintercreeper has escaped cultivation in all the eastern states. It’s frequently found near urban centers, with heavy infestations in woodlands around St. Louis and Kansas City.

American hazelnut is a thicket-forming shrub that grows to about 10 feet high. It is prized for its edible nuts, which are covered by a distinctive leafy or papery, jagged-edged bract.

Dogwoods usually have leaves arranged opposite one another on the stem, except for the alternate-leaved dogwood! This shrub or small tree is a popular ornamental, especially in the northern parts of Missouri, where it can be too cold to grow flowering dogwood.

White flowers clustered in round balls give buttonbush its name. It's always found near water, and thickets of buttonbush help protect lakeshores from wave action. This shrub is also planted as an ornamental.

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.

Pin oak is one of the easiest trees to recognize by its shape alone: It has a tall, straight trunk, an overall pyramidal or conical shape and, most notably, the branches on the lower third of the tree angle downward.

Native to Europe and Asia, European, or black alder is planted widely as an ornamental. In some parts of the United States and elsewhere in the world, this species becomes weedy, even invasive. In Missouri, you are most likely to encounter it in landscaped areas, and not in the wild.
