It thrives in moist prairies, riverbanks, and floodplain meadows and is ideal for riparian buffer restoration, nitrogen fixation, and wildlife cover creation.
Widely distributed in the United States east of Nebraska and south of Michigan, this perennial legume inhabits open woodlands and wet meadows. Growing best in full sun, it reaches a height of 3-6 feet. Bright yellow flowers from July-September, give way to long pea pods that remain on the plant long after it has senesced for the year.
