Field Guide

Oaks are the most important group of trees in Missouri, in both human and ecosystem value. They dominate most of the forests, woodlands, and savannas in the state. Learn more about our 22 species.

Buckbrush, or coralberry, grows throughout Missouri. This familiar thicket-forming shrub bears dense clusters of pinkish-red berries that persist through most of the winter.

Carolina moonseed is a slender, twining vine. It is scattered in southern and eastern Missouri. It bears clusters of bright red, somewhat flattened fruits. The disk-shaped seeds are spiraled like a snail shell.

Common moonseed is a rather slender, twining vine that climbs or sprawls. It occurs nearly statewide. It bears clusters of bluish-black fruits. The seeds are flattened, with a raised edge shaped like a crescent moon.

Common prickly ash is a thicket-forming shrub or small tree. Its compound leaves resemble of those of ash trees, but it’s in a different family. Pairs of stout, curved prickles occur at each node. Scattered statewide, but less common in the Ozarks.

Southern black haw is an irregularly branched shrub with shiny, dark green, opposite leaves whose lower surface is paler with scattered rusty hairs, especially on the veins. It bears clusters of white flowers, which turn into bluish-black fruits.

Missouri has seven species of elms that grow in natural settings. Elms have tough, shock-resistant wood. In the past, some species were favorite shade trees, which is why so many towns have Elm Streets. But elms have suffered for a century from a devastating fungal disease.

Missouri has six species of ashes that you might find in natural settings. They have been very popular as shade trees, and their wood is famously useful. Ash trees of all the species in North America are currently being killed by the invasive, nonnative emerald ash borer.

Missouri has five species of maples that are either native or naturalized, plus several that are known only in cultivation. Maples are important members of native ecosystems. They also provide stunning fall color, welcome shade in summer, commercially important lumber, and sap for syrup.

Black raspberries resemble blackberries, but when ripe, the fruits fall away as a caplike unit from the receptacle. Leaflets appear white underneath. The canes are whitish-coated when young; they arch down and take root at the tips. Native and scattered statewide.
