Field Guide

Eastern redbud is a native shrub or small tree that is distinctly ornamental in spring with small, clustered, rose-purple flowers covering the bare branches before the leaves.

Grown as an ornamental for its attractive pink flower clusters, gracefully spreading branches, and delicate leaves, mimosa is easily propagated and grows rapidly. Unfortunately, it is also an invasive exotic in much of the state.

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.

Amur corktree is a non-native tree that is becoming naturalized in our state. Originally introduced for landscape planting, it has proven itself invasive in the northeastern United States and has shown invasive tendencies in St. Louis.

By far the most common native conifer in the state, eastern red cedar is useful for its aromatic, red wood and beloved for its greenery, its resinous blue “berries,” and the spicy odor it lends the outdoors.

Overcup oak is fairly easy to identify. The acorns are almost completely covered by their knobby cups. The leaves have long, narrow lobes and wide sinuses. In Missouri, it grows naturally only in wet forests along the Mississippi and Meramec rivers.

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.

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.

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.
