As a legume, it plays a vital ecological role in nitrogen fixation, enriching prairie soils. Its deep taproot makes it a survivor of drought and fire, embodying the resilience of prairie ecosystems. The plant is a larval host for several native butterflies including the Southern Dogface and Reakirt's Blue.Shop Our Floral Collection
