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.

Ironweeds are tough, grayish-green, branching plants known for their fluffy-looking clusters of reddish-purple florets. They are a familiar sight on roadsides and pastures. Identify western ironweed by the bracts at the base of the flowerheads.

Hedge parsley is an introduced plant that looks a lot like parsley. It was first collected in Missouri in 1909 and has become much more abundant in recent decades as it spreads along roadsides and railroads.

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.

Wild onion is edible and is also favored by native-plant gardeners, who enjoy its showy umbels of pink flowers and tolerance of dry, rocky sites. This Ozark species blooms in summer and fall.

Tall bellflower is an abundant native bellflower that is easily identified by its stout, tall habit, short, wheel-shaped, blue corolla, and the curved, purple style that projects beyond the flower.

White snakeroot looks very similar to thoroughworts, but it has triangular leaf blades that are more broadly angled or rounded at the base. White snakeroot is common statewide. It’s a toxic plant if eaten, so it’s good to be able to identify it.

A stout perennial that can grow to 6 feet tall, tall thoroughwort is a member of the sunflower family that has dull white flowers and distinctive leaves that are opposite, slender, very short-stalked, and with three quite noticeable veins.

Rough blazing star is fairly common and scattered nearly statewide. To distinguish between Missouri’s nine species in the genus Liatris, start by noting details of the flower structure. It’s not hard when you know what to look for.

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.
