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!

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!

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.

There’s no mistaking Kentucky coffee tree when its large, tough seedpods are hanging from its limbs or dropping to the ground below. Unpopular as food with today’s wildlife, these seedpods might have fed mastodons and other large, extinct North American mammals.

Black oak grows throughout Missouri, in upland woods, on glades, and along borders of woods and fields. It and scarlet oak were the primary colonizers of Ozark pinelands when the native pines were cleared in the early 1900s.

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.
