Illustration of green ash leaf.
Green Ash
Fraxinus pennsylvanica
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
Fraxinus americana
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.

Black Walnut
Juglans nigra
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.
Illustration of bitternut hickory leaves and nuts.
Bitternut Hickory
Carya cordiformis
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!

Pecan
Carya illinoinensis
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.

Butternut
Juglans cinerea
Butternut, or white walnut, is closely related to the more common black walnut. Both have delicious edible nuts, and both are valued for their wood. Butternut, however, is declining due to a usually fatal fungal disease.
Illustration of mockernut hickory leaf, fruit.
Mockernut Hickory
Carya tomentosa
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.
Illustration of box elder leaves and fruits.
Box Elder
Acer negundo
A member of the maple family, box elder is often confused with poison ivy because its compound leaves sometimes grow in threes (though also in fives). A fast-growing tree, its winged seeds betray its relationship to other maples.
Illustration of tree-of-heaven leaves, flowers, fruit
Tree-of-Heaven
Ailanthus altissima
Tree-of-heaven is a fast-growing exotic that is common in urban areas. It is weedy and aggressive and should not be planted. It has 2-foot-long feather-compound leaves. Twigs smell unpleasant when you break them.
Illustration of American bladdernut leaves, flowers, fruits.
American Bladdernut
Staphylea trifolia
American bladdernut is a thicket-forming shrub or small tree that grows in moist soils. It produces clusters of bell-shaped white flowers in spring and unusual 3-parted air-filled capsules in late summer that turn papery and persist into winter.

About Trees, Shrubs and Woody Vines in Missouri

There are no sharp dividing lines between trees, shrubs, and woody vines, or even between woody and nonwoody plants. “Wood” is a type of tissue made of cellulose and lignin that many plants develop as they mature — whether they are “woody” or not. Trees are woody plants over 13 feet tall with a single trunk. Shrubs are less than 13 feet tall, with multiple stems. Vines require support or else sprawl over the ground.
