Field Guide

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.

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.

Of the several hickories in Missouri, bitternut hickory is the only one with long, bright yellow buds. Its common name refers to the bitter taste of the nut — but the flavor doesn't put off squirrels, mice, and deer!

The pecan, a type of hickory, is one of Missouri’s favorite nut trees. Originally pecan had a fairly limited, southern distribution, but today it is found in and out of cultivation nearly statewide, owing to the popularity of the nuts.

Missouri is rich with hickory trees. Mockernut hickory stands out from the rest for its hard wood, thick-shelled fruit enclosing relatively small kernels, large and light-colored terminal buds, and tight, never shaggy, bark.

Named for the cottony fluffs of hairs attached to its tiny seeds, cottonwood thrives in moist lowlands near streams and rivers. It is Missouri’s fastest-growing native tree but pays for that distinction by being relatively short-lived.

American hornbeam is also called musclewood because of the sinewy appearance of its smooth gray bark. The name hornbeam refers to the genuine strength of its wood — it is one of the hardest and strongest woods in North America.

Eastern hop hornbeam is named for its fruits, which are clusters of flattened, papery, scalelike sacs arranged in an overlapping pattern, like scales on a pinecone — resembling the hops that beer is made from.

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.
