Field Guide

In summer, you’re almost guaranteed to see big colonies of crown vetch along Missouri's highways. This weedy nonnative plant stabilizes the dirt after road construction but degrades our natural ecosystems.

Small bluet is a mat-forming winter annual that can color entire lawns blue with its tiny flowers. You can start learning to recognize it by noting the reddish-purple color at the center of the blue-violet flowers.

Missouri has one introduced and four native wood sorrels. Violet wood sorrel is the only one that has magenta or lavender flowers.

Johnny-jump-up is a flat-faced violet whose small flowers are a washed-out blue or violet with a very light yellow or white center. Look for it in fields, meadows, glades, rights-of-way, disturbed sites, and possibly your front lawn.

Ironweeds are tough, grayish-green, branching plants known for their fluffy-looking clusters of reddish-purple florets. They are a familiar sight on roadsides and pastures. Identify western ironweed by the bracts at the base of the flowerheads.

One of Missouri’s five types of echinaceas, glade coneflower is distinguished by its yellow pollen, drooping pink or purple ray flowers, and narrow, tapering leaves. Look for it in the eastern Ozarks, and at native plant nurseries!

Korean lespedeza is an Asian clover that was introduced to North America to prevent erosion, to feed wildlife and livestock, and, since it is a legume, to add nitrogen to the soil. A weedy plant, it has spread statewide since the 1930s.

In spring, wild hyacinth bears an elongated cluster of pale blue flowers with prominent anthers that sway on stalks up to 2 feet tall.

Tall bellflower is an abundant native bellflower that is easily identified by its stout, tall habit, short, wheel-shaped, blue corolla, and the curved, purple style that projects beyond the flower.

Rough blazing star is fairly common and scattered nearly statewide. To distinguish between Missouri’s nine species in the genus Liatris, start by noting details of the flower structure. It’s not hard when you know what to look for.
