Field Guide

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.

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.

Existing in thousands of acres of nearly pure stands, shortleaf pine was once the dominant tree in much of the Missouri Ozarks. Today, Missouri’s only native pine tree is recovering from the extensive logging that had exhausted its old-growth stands by the 1920s.

Bald cypress is an “evergreen” tree that is not evergreen! Like the leaves of hardwoods, its needles turn yellow in the fall and are shed. A tree associated with swamps, its impressive form also graces many public landscapes.

By far the most common native conifer in the state, eastern red cedar is useful for its aromatic, red wood and beloved for its greenery, its resinous blue “berries,” and the spicy odor it lends the outdoors.

Primarily a landscaping tree, Austrian pine sometimes reproduces here on its own, and for this reason it's officially included in the flora of our state. Usually, you find it in urban and suburban ornamental plantings or, if you're out hiking, persisting at old home sites.
