Field Guide

White crownbeard is a tall native perennial wildflower with clusters of white flowerheads. It's called “wingstem” for the narrow green wings running along the stem. It’s called “frostweed” because it forms "frost flowers": strange and beautiful formations at the stem bases after a sudden hard frost.

Compass plant grows to 8 feet tall and has foot-long, deeply cleft leaves at its base. It got its common name because its leaves turn so that the surfaces face east and west to take full advantage of the sun’s rays.

Of Missouri’s six rosinweeds, prairie dock is identified by its large, leathery, unlobed leaves, which are nearly all in a basal whorl. Only a few small leaves grow on the stem.

Narrow-leaved vervain is a short, slender perennial with single stems or with upper stems sparingly branched. Its many small flowers are crowded on narrow spikes. The corollas are tubular, deep lavender or purple, with 5 spreading lobes.

Sometimes called wild oregano, dittany, like true oregano, is a member of the mint family and can be used as a culinary herb and in teas. Look for it on dry, wooded slopes in Ozark counties.

Common ground cherry is closely related to the tomatillo, which you’ve probably seen in the grocery store or had in a delicious salsa verde at a Mexican restaurant. The fruits of ground cherry are edible, too.

Horse nettle is a native perennial with spiny stems and leaves, white to purplish flowers, and toxic fruits that look like tiny yellow tomatoes. It does well in disturbed habitats, and many people consider it a weed.

Ox-eye daisy, though familiar, is not native to North America. It was introduced long ago from Eurasia. Common in grassy uplands, pastures, fencerows, and roadsides, it can colonize aggressively in the garden.

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.

Named for its resemblance to a European herb that was popular in Medieval times, golden Alexanders is a native Missouri wildflower with bright yellow flowers arranged in umbrella-like clusters.
