Thermopsis rhombifolia
Native to the Rocky Mountains this plant was discovered along an abandoned railroad grade in Douglas County, Wisconsin in the late 1990s. I took some root cuttings and transplanted these to a wild garden in my yard. Over the years the plants have slowly expanded from their original spot and now cover many square feet.
Seed pods (seldom produced and the seeds apparently inviable) are arcuate.
''Thermopsis rhombifolia'', also known as prairie thermopsis, is a flowering plant in the legume family. It is native to North America, where it is found in the Great Plains, with extensions into the lower canyons of the Rocky Mountains. Its natural habitat is dry grasslands and woodlands.
