Field Guide

You might see common buckthorn for sale at a nursery, but don’t buy it! At least six states have banned this invasive exotic, and the difficult-to-control plant is causing problems here in Missouri, too. Learn how to identify it — and avoid it!

Shingle oak got its name because the naturalist who discovered it noticed that French colonists in Illinois were using the wood to make roofing shingles. The leaves resemble those of laurel (bay), lacking lobes or teeth — but laurel trees don't bear acorns!

American hazelnut is a thicket-forming shrub that grows to about 10 feet high. It is prized for its edible nuts, which are covered by a distinctive leafy or papery, jagged-edged bract.

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.

Dogwoods usually have leaves arranged opposite one another on the stem, except for the alternate-leaved dogwood! This shrub or small tree is a popular ornamental, especially in the northern parts of Missouri, where it can be too cold to grow flowering dogwood.

Limited in our state to well-drained, sandy soils in southeast Missouri, American beech is an impressive tree that has provided Americans with wood for a variety of uses, from furniture to toys to fuel to beer barrels!

Ozark witch-hazel is a large native shrub that grows along dry, rocky streambeds in southern and east-central Missouri. The yellow, ribbonlike flowers bloom as early as January. In the fall, the seeds are ejected forcefully, to a distance of up to 30 feet!

Chinkapin oak is fairly easy to identify because of its distinctively toothed leaves. Look for it growing in rocky soils derived from limestone or dolomite on bluffs and in upland woods, and in floodplain forests and lower slopes along streams.
