Field Guide

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.

Each summer, the bright orange and red “trumpets” of this woody vine decorate Missouri’s cliff faces, telephone poles, and anything else strong enough to support it. Hummingbirds zoom to trumpet creeper’s flowers for their nectar.

Ozark witch-hazel is a large native shrub that grows along dry, rocky streambeds in southern and east-central Missouri. The yellow, ribbonlike flowers bloom as early as January. In the fall, the seeds are ejected forcefully, to a distance of up to 30 feet!

Chinkapin oak is fairly easy to identify because of its distinctively toothed leaves. Look for it growing in rocky soils derived from limestone or dolomite on bluffs and in upland woods, and in floodplain forests and lower slopes along streams.

Of the three species of catalpas in our state, northern catalpa is the only one native to Missouri (specifically, the Bootheel region). It has been planted widely, though, and has naturalized in many places. A popular ornamental and shade tree with pretty, orchidlike flowers and long, beanlike fruit.

Nannyberry is an understory shrub or small tree that grows in low woods, wooded slopes, and rich valleys near streams. It is officially a Species of Conservation Concern in our state, but its rarity here may be because Missouri is at the southern end of its range.

Shumard oak is worth knowing: it can rise to 100 feet in height and gain a trunk diameter of 5 feet, with wide-spreading, muscular boughs.

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.

In Missouri, Nuttall's oak grows naturally only in Bootheel. With its limited range, and with steady destruction of its habitat, it has become rare and imperiled within our borders.
