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.

The small, cloverlike flowering heads and trifoliate leaves of black medick are clues that this plant is in the Fabaceae, the bean or pea family. An introduced, weedy species, it is closely related to alfalfa.

Running buffalo clover spreads by sending out long, creeping runners. Now endangered, this native perennial once flourished along streams and buffalo trails throughout the grasslands of the eastern and central United States.

The smooth, finely divided, fernlike foliage of pale corydalis is similar to that of the related wildflower Dutchman’s breeches. But in pale corydalis, the small yellow flowers appear tubelike and lipped.

Wild strawberry is one of the parents of the cultivated strawberry and is one of our prized native wild edibles. It’s also a valuable food for innumerable animals, and it’s attractive in native wildflower gardens.

Bird’s-foot trefoil forms low patches of bright yellow flowers along roadsides, having been planted to stabilize soil after road construction. Up close, it clearly has pea flowers. The leaves are cloverlike, with two leafy stipules at the base of each.

A bushy native perennial legume with small clusters of pink flowers, slender bush clover provides nectar for numerous insects. Several types of birds eat the seeds, and many mammals eat the foliage.

Leaf cup is named for the leafy appendages that wrap around the stem at the bases of the opposite leaves. Part of the sunflower family, leaf cup has about 8 white ray florets surrounding yellow disk florets.

Found mainly in the southern half of the state, in prairies and glades, prairie parsley is an upright, stout-stemmed perennial with small yellow flowers in umbrella-shaped clusters. It blooms April through June.

One of our more challenging plants to identify, meadow parsnip looks an awful lot like golden Alexanders. But you can do it! Look closely at the flower clusters and at the edges of the leaves, and then check the seeds.
