Scientific Name
Lespedeza cuneata
Description
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.

About Wildflowers, Grasses and Other Nonwoody Plants in Missouri
A very simple way of thinking about the green world is to divide the vascular plants into two groups: woody and nonwoody (or herbaceous). But this is an artificial division; many plant families include some species that are woody and some that are not. The diversity of nonwoody vascular plants is staggering! Think of all the ferns, grasses, sedges, lilies, peas, sunflowers, nightshades, milkweeds, mustards, mints, and mallows — weeds and wildflowers — and many more!
