The name Amorpha is derived from the Greek for for "deformed" because the unusual flowers in this genus contain only 1 petal. The common name "leadwort" (which is also used for plumbago and ceratostigma) was assigned because of the belief that amorpha plants preferred to grow in soils containing lead ore.
