Leadplant is considered to be one of the most important prairie legumes.
Its foliage is high in nutrient content and is eaten by cattle and white-tailed deer. Many butterflies use it as a larval host. Its abundance can be used to assess the health of rangelands. Native Americans used it as a beverage, for smoking, a treatment for eczema, pinworms, stomach pain, rheumatism and neuralgia.
