Field Guide

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.

River birch is a native tree easily identified by its reddish, papery, peeling bark. It is used extensively in landscaping, where many-stemmed groupings are planted in moist places in yards and along streams and ponds.

The dwarf chestnut oak, though only 3–10 feet tall and the shortest of Missouri's oaks, can nevertheless produce abundant acorns that are relished by several types of birds and mammals.

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.

Ward's willow, or Carolina willow, is one of the first woody species to occupy the outer edges of gravel bars in a stream. Common in the Ozarks, it occurs nearly statewide.

A clumped shrub that grows naturally only in the northeastern part of Missouri, meadow willow lives in low, wet ground in mud or sandy gravel along streams and in wet meadows. Rare in our state, it is perhaps best identified by examining the leaves.

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!

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.

Winged sumac is most common south of the Missouri River. The "wings" in the name refer to the narrow, flattened leafy structures running along the central stems of the compound leaves.
