Field Guide

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.

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 dark, mysterious 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.

One of our beautiful, native Missouri honeysuckles, yellow honeysuckle grows mainly in the Ozarks. Unlike the invasive Japanese honeysuckle, this plant is not aggressive and makes a wonderful trellis vine for the ecology-minded gardener.

Limber honeysuckle is a native Missourian. It's uncommon and widely scattered in the state, but it does well as a trellis vine. Identify it by its crowded clusters of tubular, yellow or greenish-yellow flowers, tinged with red, purple, or pink, that are noticeably enlarged on one side at the base.

One of Missouri's beautiful native honeysuckles, grape honeysuckle is found mainly in the northern two-thirds of the state. In the native plant garden, it is easy to grow, but it is not aggressive like the introduced invasive Japanese honeysuckle.

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.

Flowering dogwood is a beautiful shrub to small tree with a straggling, spreading crown. Missouri’s official state tree, it presents lovely boughs of white inflorescences in springtime forests.

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.

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.
