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.

Grown as an ornamental for its attractive pink flower clusters, gracefully spreading branches, and delicate leaves, mimosa is easily propagated and grows rapidly. Unfortunately, it is also an invasive exotic in much of the state.

Green ash is one of the most widely planted shade trees around homes and along streets. In the wild, it lives along streams and in low grounds. Sadly, it is one of the trees most vulnerable to the emerald ash borer, an exotic invasive pest.

White ash leaves turn shades of yellow and purple in fall, and that is one reason it has been a popular landscaping tree. Many birds and mammals feed on the paddle-shaped seeds.

Easily Missouri’s most valuable tree, the black walnut provides the finest wood in the world, as well as delicious nuts. Both are in high demand and thus form an important part of Missouri’s economy.

Of the several hickories in Missouri, bitternut hickory is the only one with long, bright yellow buds. Its common name refers to the bitter taste of the nut — but the flavor doesn't put off squirrels, mice, and deer!

The pecan, a type of hickory, is one of Missouri’s favorite nut trees. Originally pecan had a fairly limited, southern distribution, but today it is found in and out of cultivation nearly statewide, owing to the popularity of the nuts.

A member of the maple family, box elder is often confused with poison ivy because its compound leaves sometimes grow in threes (though also in fives). A fast-growing tree, its winged seeds betray its relationship to other maples.

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.

Occasionally confused with poison ivy, Virginia creeper is easily identified by simply noticing that most of its leaflets are in fives, instead of threes. This common native vine is useful in landscaping.
