Description

Illinois bundleflower is a native warm-season perennial leguminous forb adapted to the central and eastern regions of the United States extending from Mexico into Canada.  Illinois bundleflower is found in prairie remnants, sloughs, woodland edges, or disturbed areas.  It does best on medium textured soils, but will grow on a wide range of soills with an annual rainfall range of 16 to 32 inches. The seeds are readily consumed by upland game birds and the plant is highly palatable livestock and deer. Illinois bundleflower is an attractive plant in the landscape because of its unique fern appearance and the closing and opening of the leaves in response to sunlight and heat.
