 While driving through Wyoming, you may come across large stands of yellow flowered plants like the ones around me. This forb is known as yellow sweet clover. Yellow sweet clover is not native to Wyoming and is originally from Europe. This plant is most often a biennial, meaning it takes two growing seasons to mature. During the first growing season, the roots are developed. Plants then produce seeds with the second year of growth. Although yellow sweet clover is introduced, the forb does provide quality forage for many native wildlife species in Wyoming and serves as an important nesting and hiding cover. Pollinators enjoy and frequently utilize the plants. Sweet clover also fixes nitrogen in the soil, which can benefit other species. When mixed among alfalfa and other grasses, yellow sweet clover can make for a quality hay. While the plant itself is not poisonous, sweet clover can harboring mold that is poisonous to livestock. A good time to look for yellow sweet clover is in June and July following several wet growing seasons. Yellow sweet clover occupies a wide variety of habitats that includes road sides to native rangelands where it often can displace native plants.
