It seems the seeds of the Illinois Bundleflower are best eaten by livestock and wildlife.
Illinois Bundleflower is a very important forb for restorations and wildlife habitat. As a legume, it helps to build the soil. It is winter-hardy, drought tolerant, and will grow in a variety of soils. Nutritious and readily eaten by all classes of livestock, Illinois Bundleflower will attract deer and game birds to any area where it grows.
