Field Guide

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.

Pondberry is a colony-forming shrub that grows in swampy depressions in lowland forests. It is an Endangered species. In Missouri, only one population occurs, in southern Ripley County.

White mulberry was introduced from Asia for its berries and as fodder for an attempted silkworm industry. Birds have helped spread white mulberry so much that in many places it is more common than our native red mulberry.

The white, smooth-looking limbs of sycamore rise over countless streams and river banks, as well as over sidewalks and city streets. The leaves, which somewhat resemble those of maples, can reach remarkably large sizes.

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.
