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.

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.

Pinesap is a plant that puts the "wild" in wildflower! It lacks chlorophyll, so its roots connect to fungi underground and absorb nutrients from the fungi.

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.

Showy clusters of blue-violet, two-lipped flowers adorn downy skullcap. This native mint is found mostly in the southern half of the state.

Large-flowered gaura is a tall plant whose white flowers turn pinkish as they age. Four petals point upward, then bend back, and 8 stamens droop downward. The flowers look something like small butterflies.
