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 common violet can be violet, white, or white with violet mottling or spots. One of 17 species or violets in Missouri, it occurs statewide in a variety of habitats. Note its heart-shaped or rounded, scalloped leaves, and (usually) the presence of hairs on stems and/or foliage.

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.

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.

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!

Nodding ladies’ tresses is the most common of Missouri’s eight species of ladies' tresses. The flowers are arranged in a spiral pattern on the upright flowering stem. Each small flower is a little white orchid.

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.

Pencil flower is small and often overlooked. It has wiry stems, long, bristly hairs, three-parted leaves, and orangish-yellow flowers.
