Dead nettle, like its close relative henbit, is a common, weedy mint that, in early spring, can carpet wide patches of disturbed ground. Recognize dead nettle by the pyramidal look of its purple- or blue-tinted foliage.

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.

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.

The petals of long-leaved bluets are not blue; they are white, often tinged with pink. Look for it in rocky, open Ozark woods, prairies, glades, and old fields in the southeastern half of the state. It prefers acid soils.

Moth mullein is a native of Eurasia introduced to our continent in the early 1800s. Since then, it has spread across North America. It’s named because the fuzzy flower, with 2 antennalike stamens, looks something like a moth.

Rock pink is a succulent perennial with slender, naked flower stalks and bright magenta flowers that usually don't open until after noon. Leaves are basal and fleshy, to 2 inches long. Look for this plant in glades and other hot, dry, rocky places.
