Field Guide

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.

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.

In nature, silver maple is a bottomland tree. Silver maples pay for their rapid growth by having rather brittle branches that easily break off in windy and other inclement weather.

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.

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!

Pin oak is one of the easiest trees to recognize by its shape alone: It has a tall, straight trunk, an overall pyramidal or conical shape and, most notably, the branches on the lower third of the tree angle downward.

Poison ivy is a toxic plant that contains an oil in all its parts that, if you come into contact with it, can cause an intense skin reaction. Learn to recognize it, and sidestep it on your outings.

An attractive shrub with wide-spreading, graceful, recurved branches and bark peeling off in conspicuous thin strips, ninebark is found throughout southern and eastern Missouri on gravel bars, rocky stream banks, and bluffs along streams. It's very popular as a native landscaping shrub, too.
