Illinois Bundleflower, or Desmantus illinoensis, is a perennial wild flower that is deep-rooted and a legume that grows throughout the plains and prairies of the United States. Illinois Bundleflower is both winter hardy and drought resistant and will grow on a wide range of soil types, from clays to sandy loams.
