Field Guide

Post oak has long been favored for fence posts and was valued by American pioneers. It has distinctive cross- or ghost-shaped leaves. It grows in rocky upland woodlands and in flatwoods on broad ridges.

Scarlet oak is a common tree of the Missouri Ozarks. Today it occupies much the same area that shortleaf pine used to dominate before it was extensively cut prior to the 1920s.

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.

Unlike its cousin poison ivy, fragrant sumac is a peasant, nontoxic plant. Note the middle leaflet of its "leaves of three": On fragrant sumac, there is no (or at most a very short) leaf stalk on that middle leaflet. Also, fragrant sumac has hairy, reddish fruits (not waxy whitish ones).

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.

Red maple is one of our most useful — and beautiful — native trees. You can find it in the woods as well as in landscape plantings statewide. Many horticultural varieties are available at nurseries.

Sugar maple is a tree that inspires much “oohing and aahing” during fall color season. Its sap is famous as a source for maple syrup, but its use in landscaping and for furniture is also widespread.
