One of a few true prairie shrubs left in Illinois, found almost exclusively in prairie remnants and open savannas. Its white flowers brighten the grassy expanses from late June to early August and can really bring in the pollinators. Needs full sun and well-dr ... ained soils to get best results in growth. Wet ground is not recommended. Though not a legume, it does fix nitrogen in nodules in the roots, adding nutrients to the soil. We recommend that you add wire protection from rabbits and others for the first year.
