Field Guide

Green ash is one of the most widely planted shade trees around homes and along streets. In the wild, it lives along streams and in low grounds. Sadly, it is one of the trees most vulnerable to the emerald ash borer, an exotic invasive pest.

White ash leaves turn shades of yellow and purple in fall, and that is one reason it has been a popular landscaping tree. Many birds and mammals feed on the paddle-shaped seeds.

A beautiful tree, swamp white oak features bicolored leaves that are shiny, dark green above and downy white below. When a breeze sets them in motion, their wavy or lobed shapes add a calm grace to a summer's hike.

This tree has two names as well as two leaf types! In Missouri, southern red oak, or Spanish oak, occurs natively only in our southeast and southernmost counties.

Many Missouri trees are quite useful, and shagbark hickory is a great example. Its wood makes excellent, slow-burning charcoal, its nuts are edible, and its wood is used for many implements. Wildlife from moths to squirrels to bats appreciate shagbarks, too!

Shellbark hickory is the largest of the true hickories and has the best-tasting hickory nuts in Missouri. Compared to shagbark hickory, it has larger leaves and more leaflets, plus larger nuts and orange twigs.

The pecan, a type of hickory, is one of Missouri’s favorite nut trees. Originally pecan had a fairly limited, southern distribution, but today it is found in and out of cultivation nearly statewide, owing to the popularity of the nuts.

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.

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.
