A second subspecies, Amorpha herbacea subsp. crenulata is Endemic to Dade County.  Considered to by Endangered by the State of Florida and by the USFWS. Can be used as a specimen plant in a sunny spot or as a moderately tall wildflower.

Interesting pink veined foliage, showy flowers. Often lies on its side with the flowers held somewhat above the rest of the plant. Has an extremely deep taproot.  Is notoriously difficult to transplant. Small specimen plant.

Flowers have yellow tepals but the inflorescence has abundant white hairs which provide an overall white aspect in the landscape. The species is named for its red roots and rhizomes. Feral hogs love this plant and will dig up extensive areas to get the roots.  The plant in turn recovers quickly and new plants come up from the fragmented rhisomes. Groundcover or mass planting in moist areas.
