Field Guide

The yellow violet is Missouri's only all-yellow violet. This native wildflower is less common than violet violets. Look for it in low woods, rich slopes, and wooded floodplains.

Mullein immigrated to America along with Europeans, and with them it has spread across the continent. Its fuzzy, green-gray rosettes of leaves and tall spikes of yellow flowers make it easy to identify.

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.

A low-growing wildflower that can colonize large areas along roadsides, showy evening primrose bears pink or white flowers that seem too large for the vegetation that supports them.

Hispid buttercup is a densely hairy plant with showy yellow flowers. It is found mostly in the southern half of Missouri, usually in moist locations.

A common spring wildflower found in forests nearly statewide, large bellwort has bell-shaped flowers that droop downward. The yellow petals sometimes look twisted, almost wilted.

Many Missouri children learn about this orange-flowered native plant by playing with the juicy green seedpods, which, when ripe, "explode" upon the slightest touch. This is jewelweed's mechanism for seed dispersal, and it's the reason for the name "touch-me-not."

There are 3 species of Aureolaria in Missouri. Only combleaf yellow false foxglove is annual, has fernlike, delicately dissected leaves, and glandular hairs. It occurs in the Ozarks.

Water primrose is a common shoreline plant with bright yellow flowers and long, trailing stems. It grows in dense mats in the shallow areas of ponds, lakes, and streams.

Yellow lady’s slipper is found statewide. It is among our showiest native orchids, and suffers from its popularity. Although orchids rarely survive transplanting, people try digging them up anyway.
