Field Guide

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.

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.

Red maple is one of our most useful — and beautiful — native trees. You can find it in the woods as well as in landscape plantings statewide. Many horticultural varieties are available at nurseries.

Sugar maple is a tree that inspires much “oohing and aahing” during fall color season. Its sap is famous as a source for maple syrup, but its use in landscaping and for furniture is also widespread.

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.

Don’t kid yourself about this invasive, exotic vine: Japanese honeysuckle is an aggressive colonizer that shades out native plants and harms natural communities. Learn how to recognize it!

Introduced from Asia as a groundcover, wintercreeper has escaped cultivation in all the eastern states. It’s frequently found near urban centers, with heavy infestations in woodlands around St. Louis and Kansas City.
