Field Guide

Easily Missouri’s most valuable tree, the black walnut provides the finest wood in the world, as well as delicious nuts. Both are in high demand and thus form an important part of Missouri’s economy.

Our state flower, the hawthorn, is solidly represented in Missouri. There are about 100 different kinds of hawthorns that occupy almost every kind of soil in every part of the state. These members of the rose family are closely related to apples.

Possum haw, or deciduous holly, is the more common of two native Missouri hollies that lose their leaves each fall. This shrub or small tree is eye-catching in the fall and winter with its bright red berries.

'Bradford', a type of Callery pear, has been hugely popular in landscaping, but it can escape and hybridize with relatives. Alarmingly, it has become an invasive plant. Learn more about this problem tree.

Black haw is a small understory tree with beautiful fall color — deep lavender or maroon-purple, finally becoming deep rose-red. Its clusters of blue-black berries, borne on red stalks, happen to be quite tasty. No wonder it has been cultivated as an ornamental since 1727!

Prairie crab apple is an attractive, small, ornamental tree with low, crooked branches and attractive spring flowers. Its hard, bitter fruits can be used in making tasty jellies, cider, and vinegar.

Common hackberry is named for its sweet, purple, edible fruits, but most people identify hackberry with its weird-looking bark, which develops numerous corky, wartlike projections and ridges.

Until Dutch elm disease came to America, the large, graceful American elm was widely planted along city streets and was beloved as the all-American shade tree. Now large specimens are rare, since the deadly fungus usually kills trees before they reach fine old ages.

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.

Occasionally confused with poison ivy, Virginia creeper is easily identified by simply noticing that most of its leaflets are in fives, instead of threes. This common native vine is useful in landscaping.
