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!

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.

Gray dogwood is a deciduous, thicket-forming shrub. Its small, creamy-white flowers occur in branched clusters, and its white or pale blue fruits are supported by red stalks — a characteristic that makes it attractive for ornamental uses.

Rough-leaved dogwood is one of Missouri's hardiest shrubs, capable of withstanding cold and drought. The leaves of this thicket-forming species emit a faint odor of sour milk.

Black locust, a member of the bean family, is easy to appreciate in May and June, when its showy white clusters of flowers perfume the breeze with their sweet smell. Bees like the flowers, too.
