Field Guide

Of the three species of catalpas in our state, northern catalpa is the only one native to Missouri (specifically, the Bootheel region). It has been planted widely, though, and has naturalized in many places. A popular ornamental and shade tree with pretty, orchidlike flowers and long, beanlike fruit.

White flowers clustered in round balls give buttonbush its name. It's always found near water, and thickets of buttonbush help protect lakeshores from wave action. This shrub is also planted as an ornamental.

Gray dogwood is a deciduous, thicket-forming shrub. Its small, creamy-white flowers occur in branched clusters, and its white or pale blue fruits are supported by red stalks — a characteristic that makes it attractive for ornamental uses.

Rough-leaved dogwood is one of Missouri's hardiest shrubs, capable of withstanding cold and drought. The leaves of this thicket-forming species emit a faint odor of sour milk.

One of our beautiful, native Missouri honeysuckles, yellow honeysuckle grows mainly in the Ozarks. Unlike the invasive Japanese honeysuckle, this plant is not aggressive and makes a wonderful trellis vine for the ecology-minded gardener.

Limber honeysuckle is a native Missourian. It's uncommon and widely scattered in the state, but it does well as a trellis vine. Identify it by its crowded clusters of tubular, yellow or greenish-yellow flowers, tinged with red, purple, or pink, that are noticeably enlarged on one side at the base.

One of Missouri's beautiful native honeysuckles, grape honeysuckle is found mainly in the northern two-thirds of the state. In the native plant garden, it is easy to grow, but it is not aggressive like the introduced invasive Japanese honeysuckle.

Shrubby St. John’s-wort has shiny, somewhat leathery, opposite leaves, 2-edged twigs, and flowers with 5 bright yellow petals and many stamens. A shrub growing to 6 feet tall, it is scattered nearly statewide.
