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.

Colonies of smooth sumac are most noticeable in early autumn, because the leaves turn brilliant red! You can make drinks and jellies from the clusters of fuzzy red berries.

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.

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!

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.

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.
