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.

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.

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.

Possum haw, or deciduous holly, is the more common of two native Missouri hollies that lose their leaves each fall. This shrub or small tree is eye-catching in the fall and winter with its bright red berries.

'Bradford', a type of Callery pear, has been hugely popular in landscaping, but it can escape and hybridize with relatives. Alarmingly, it has become an invasive plant. Learn more about this problem tree.

Black haw is a small understory tree with beautiful fall color — deep lavender or maroon-purple, finally becoming deep rose-red. Its clusters of blue-black berries, borne on red stalks, happen to be quite tasty. No wonder it has been cultivated as an ornamental since 1727!
