Field Guide

Willow oak's leaves are narrow, pointed, and willowlike, and like willows, this oak is associated with wet ground. In Missouri, willow oak is only found natively in our southeastern counties.

A clumped shrub that grows naturally only in the northeastern part of Missouri, meadow willow lives in low, wet ground in mud or sandy gravel along streams and in wet meadows. Rare in our state, it is perhaps best identified by examining the leaves.

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.

Corkwood is a rare and unusual small tree that doesn’t have a problem with having its feet wet for long periods of time, but it grows rarer as its swampy habitat is converted to cropland.

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.
