Field Guide

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.

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.

Red mulberry is native to Missouri and North America. You can distinguish it from the introduced white mulberry tree, which is a noxious weed, by its leaves and fruits.

Named for the cottony fluffs of hairs attached to its tiny seeds, cottonwood thrives in moist lowlands near streams and rivers. It is Missouri’s fastest-growing native tree but pays for that distinction by being relatively short-lived.

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.

Found nearly statewide, slippery elm has fuzzy twigs and reddish hairy buds, which often attract attention in wintertime. Its inner bark is reddish and rather slimy, which gives this tree its name "slippery."

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.
