Canada milk vetch is a robust native legume that enriches the soil through nitrogen fixation, making it a valuable addition to native plant gardens and prairie restorations. It prefers partial shade to full sun and consistently moist, well-drained soils, and tolerates a wide range of soil types. Water regularly during establishment and allow it space to spread, as it can form attractive colonies over time.
