Description
These annual plants are characterized by longitudinally folded, lobed, leaflike bracts that persist throughout the growing season. The seeds are small, egg-shaped and dark brown to light gray or tan. The leaves and leafy bracts change from green to copper in the fall as the mature seeds drop. Three-seeded mercury can be found throughout the Midwest from bottomland forests to upland prairies, pastures, old fields and disturbed places. Three-seeded mercury responds well to disking and fertilizer and often occurs along crop fields.
Bloom period
May to October
Use by bobwhites
Many insects are attracted to three-seeded mercury, making it a component of brood habitat for quail. Seeds are readily used by quail for food.
