Field Guide

The interesting, bright yellow flowers of showy partridge pea are immediately recognizable. At night, the leaflets close and pull upward into a sleeping position.

The flowers of blue-eyed Mary are only about a half inch wide, but this pretty wildflower makes up for it by usually appearing in abundance, covering a patch of forest floor with little sky-blue and white “faces.”

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

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

Because each plant disperses a large number of seeds, garlic mustard can outcompete native vegetation for light, moisture, nutrients, soil, and space as it quickly colonizes an area.

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.

To distinguish false rue anemone from "true" rue anemone, look for the following: 5 white (not pinkish) sepals, and leaves present on the flowering stems. Confirm your identification by noting that it's growing in a colony (not singly) and is in a moist, low area.

White anemone is a showy native wildflower with interesting, deeply toothed leaves. Often occurring in colonies, it spreads easily (even aggressively) from rhizomes and is sometimes cultivated in wildflower gardens.

Wild onion is edible and is also favored by native-plant gardeners, who enjoy its showy umbels of pink flowers and tolerance of dry, rocky sites. This Ozark species blooms in summer and fall.
