Field Guide

Though it only occurs naturally in the southeastern part of Missouri, the stately tulip tree is planted widely in lawns, parks, and cemeteries. The distinctive leaves and tulip-shaped flowers make it easy to identify.

American hornbeam is also called musclewood because of the sinewy appearance of its smooth gray bark. The name hornbeam refers to the genuine strength of its wood — it is one of the hardest and strongest woods in North America.

Until Dutch elm disease came to America, the large, graceful American elm was widely planted along city streets and was beloved as the all-American shade tree. Now large specimens are rare, since the deadly fungus usually kills trees before they reach fine old ages.

Introduced to the United States in the middle 1800s, Siberian elm pays for its fast growth with brittle wood that is subject to storm damage. Its large limbs are subject to splitting from the crotches of older trees. If you are thinking of planting a Siberian elm, you might want to think again!

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.

Identify sandbar willow by its very narrow leaves with widely spaced, slender teeth along the margins. This is a good soil binder and bank stabilizer; it prevents washing and erosion of alluvial soil.

Tree-of-heaven is a fast-growing exotic that is common in urban areas. It is weedy and aggressive and should not be planted. It has 2-foot-long feather-compound leaves. Twigs smell unpleasant when you break them.

Corkwood is a rare and unusual small tree that doesn’t have a problem with having its feet wet for long periods of time, but it grows rarer as its swampy habitat is converted to cropland.

Cucumber magnolia is an impressive, large, broad-spreading shade tree native to southern Missouri. It is often cultivated in the eastern United States because, compared to more southern magnolias, it is relatively cold-hardy.
