Field Guide

Golden rain tree is native to China, Korea, and Japan. It was cultivated in Missouri for years. Because it readily escapes from cultivation and is invasive, it is no longer recommended for planting in Missouri.

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.

Colonies of smooth sumac are most noticeable in early autumn, because the leaves turn brilliant red! You can make drinks and jellies from the clusters of fuzzy red berries.

Amur corktree is a non-native tree that is becoming naturalized in our state. Originally introduced for landscape planting, it has proven itself invasive in the northeastern United States and has shown invasive tendencies in St. Louis.

American holly is Missouri's most durable broad-leafed evergreen tree. It is best known for its bright red berries and spiny green leaves at Christmas.

If there’s a giant green thicket in your woods, you may have a bush honeysuckle infestation. These invasive plants are shrubby natives of Asia. In America, where they have no natural controls, they leaf out early, grow fast, spread fast, and form dense thickets that crowd out native forest plants.

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.

A close relative of water tupelo, black gum is very popular as a landscaping tree. In the wild, it’s usually found in the Ozarks and Bootheel, but with its high popularity in landscaping, you might find it anywhere in the state.
