Field Guide

Though it doesn’t reach a stately size, honey locust commands respect for its many large, strong, usually branched thorns, which can puncture tractor tires as easily as they can poke through tennis shoes! The long, leathery, twisting pods are relished by cattle and by wildlife.

Our state flower, the hawthorn, is solidly represented in Missouri. There are about 100 different kinds of hawthorns that occupy almost every kind of soil in every part of the state. These members of the rose family are closely related to apples.

The white, smooth-looking limbs of sycamore rise over countless streams and river banks, as well as over sidewalks and city streets. The leaves, which somewhat resemble those of maples, can reach remarkably large sizes.

Exotic willows are available at lawn and garden centers, but there are several willow species that are native to Missouri. Most are rather humble colonizers of gravel bars, riverbanks, and lakesides. Many are important for human economic interests. All have a place in our wild ecosystems.

Identify sandbar willow by its very narrow leaves with widely spaced, slender teeth along the margins. This is a good soil binder and bank stabilizer; it prevents washing and erosion of alluvial soil.

Ward's willow, or Carolina willow, is one of the first woody species to occupy the outer edges of gravel bars in a stream. Common in the Ozarks, it occurs nearly statewide.

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.

Tree-of-heaven is a fast-growing exotic that is common in urban areas. It is weedy and aggressive and should not be planted. It has 2-foot-long feather-compound leaves. Twigs smell unpleasant when you break them.

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.
