Field Guide

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.

Exotic willows are available at lawn and garden centers, but there are several willow species that are native to Missouri. Most are rather humble colonizers of gravel bars, riverbanks, and lakesides. Many are important for human economic interests. All have a place in our wild ecosystems.

The dwarf chestnut oak, though only 3–10 feet tall and the shortest of Missouri's oaks, can nevertheless produce abundant acorns that are relished by several types of birds and mammals.

Persimmon is best known in the fall, when its orange, plumlike fruits come on. Be careful, however, to make sure a persimmon is ripe before you pop it into your mouth, or you could have a puckery surprise!

Osage orange is a densely branched, short-trunked, thorny tree. It bears weird-loooking, softball-sized, chartreuse, brainlike fruits, which often lie beneath the tree in abundance in autumn.
