The common violet can be violet, white, or white with violet mottling or spots. One of 17 species or violets in Missouri, it occurs statewide in a variety of habitats. Note its heart-shaped or rounded, scalloped leaves, and (usually) the presence of hairs on stems and/or 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.

An annual, spring-blooming wildflower, Miami mist has loose coils of small blue flowers with distinctive, delicate fringes on the petal lobes.

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.

Large, crinkled, palmately 5-lobed leaves distinguish golden seal, which occurs in moist woods in the Ozarks and Central Missouri. Populations have been declining due to root diggers.

Hedge parsley is an introduced plant that looks a lot like parsley. It was first collected in Missouri in 1909 and has become much more abundant in recent decades as it spreads along roadsides and railroads.

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.
