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.

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.”

Although the funnel-shaped, 5-lobed flowers look something like the petunias you find at garden centers, our wild petunia is not related to them. This ruellia often has crinkled hairs in 2 narrow, lengthwise bands on opposite sides of the stalk.

Introduced as an ornamental, beefsteak plant is native to Asia. It is common in moist or dry wooded bottomlands, open valley pastures, and along trails, railroads, and roadsides. It spreads invasively in our state.

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."

Our two Missouri jewelweeds occur in the same habitats, often side by side, and even botanists can’t tell them apart without the flowers. Pale touch-me-not is the one with the lemon-yellow flowers!

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.

Dwarf larkspur is a single-stemmed perennial with an upright flower stalk bearing racemes of bluish-purple flowers. Like other larkspurs, there is a spurlike appendage behind each flower.

These two species of sweet clover are present all over America. Although they have been planted for forage, as bee plants, and as nitrogen-fixers, white and yellow sweet clover are now classified as invasive for their weediness and the problems they pose for natural habitats.

Dutchman’s breeches, a common spring wildflower, is easy to identify. Note its bluish-green, fernlike leaves and its leafless stalks, from which dangle several white flowers shaped like old-fashioned knee breeches.
