Field Guide

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.

The bark of cherrybark oak looks like the bark of a cherry tree. When you hold one of the leaves with the leaf stalk upward, the pointed lobes make the leaf resemble an outline of a Chinese pagoda. This oak grows in Missouri's Bootheel.

Blackjack oak is common in dry upland woods, especially ones that have been badly burned. It can grow on the poorest soils. It is rugged but not worth much as lumber. It's one of the first trees to be used as fuel.

Found throughout Missouri and in all kinds of habitats, the white oak is one of our most attractive, long-lived, and stately shade trees. Learn to recognize it by its light gray bark, rounded-lobed leaves, and distinctive acorns.

Sassafras, with its aromatic oval, mitten- , and trident-shaped leaves, is rich in both human and natural history, and it can be a spectacular tree for fall color.

Bur oaks can live for hundreds of years and become giants; many have legendary or historic status. As with most oak species, it can be identified by leaf shape.

American holly is Missouri's most durable broad-leafed evergreen tree. It is best known for its bright red berries and spiny green leaves at Christmas.

Autumn olive can be found all over the state, since it was planted widely with the best of intentions. Despite its “pros,” this shrub has proven to be very invasive. It threatens native ecosystems and should not be planted.

If there’s a giant green thicket in your woods, you may have a bush honeysuckle infestation. These invasive plants are shrubby natives of Asia. In America, where they have no natural controls, they leaf out early, grow fast, spread fast, and form dense thickets that crowd out native forest plants.

Flowering dogwood is a beautiful shrub to small tree with a straggling, spreading crown. Missouri’s official state tree, it presents lovely boughs of white inflorescences in springtime forests.
