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.

Native to the northeastern United States and Canada, jack pine has been introduced in many other places, including Missouri. This scrubby tree is planted as an ornamental, for windbreaks, or for erosion control. It reproduces locally in and around places where it has been planted.

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.

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.

Shellbark hickory is the largest of the true hickories and has the best-tasting hickory nuts in Missouri. Compared to shagbark hickory, it has larger leaves and more leaflets, plus larger nuts and orange twigs.

Water hickory grows on ground that is often under water during part of the year. The bitter nuts are consumed by ducks and other wildlife.

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.

'Bradford', a type of Callery pear, has been hugely popular in landscaping, but it can escape and hybridize with relatives. Alarmingly, it has become an invasive plant. Learn more about this problem tree.

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.
