Field Guide

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.

In spring, wild hyacinth bears an elongated cluster of pale blue flowers with prominent anthers that sway on stalks up to 2 feet tall.

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.

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.

Tall thistle is a native thistle that can grow to be 10 feet tall! To identify it, notice its leaves, which are unlobed (though they may be wavy or have only shallow, broad lobes), are felty-hairy beneath, and have prickles only along the edges.

Anyone who’s seen what purple loosestrife has done to New England and the Northeast can tell you how invasive this plant is. Learn how to identify it, so you can report any findings to the Missouri Department of Conservation.

Running buffalo clover spreads by sending out long, creeping runners. Now endangered, this native perennial once flourished along streams and buffalo trails throughout the grasslands of the eastern and central United States.

Decades ago, sericea lespedeza was introduced in hopes it would provide hay, improve pastures, stop soil erosion, and supply food and cover for wildlife. Unfortunately, it has proven to be an aggressive, invasive weed that is extremely difficult to control, escapes cultivation, and outcompetes native plants.

A bushy native perennial legume with small clusters of pink flowers, slender bush clover provides nectar for numerous insects. Several types of birds eat the seeds, and many mammals eat the foliage.
