Field Guide

A beautiful tree, swamp white oak features bicolored leaves that are shiny, dark green above and downy white below. When a breeze sets them in motion, their wavy or lobed shapes add a calm grace to a summer's hike.

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.

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.

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.

Named for the cottony fluffs of hairs attached to its tiny seeds, cottonwood thrives in moist lowlands near streams and rivers. It is Missouri’s fastest-growing native tree but pays for that distinction by being relatively short-lived.

Found nearly statewide, slippery elm has fuzzy twigs and reddish hairy buds, which often attract attention in wintertime. Its inner bark is reddish and rather slimy, which gives this tree its name "slippery."

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.

Swamp chestnut oak grows in Missouri's Bootheel swamps. The leaves look something like those of true chestnut trees.
