This plant can be an annual or biennial and grows 4-6 feet tall at maturity. Its yellow flowers bloom in spring and summer and produce a fruit in pods containing one seed. This sweet-smelling plant was commonly used as a cover crop to increase nitrogen content in poor soils before the widespread use of commercial fertilizers.
