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.

Makes a nice ground cover in semi-shady to shady areas.

Noted for it's round satellite "ball" flowers and round "button" fruits. Fragrant. Sources disagree on salt tolerance of this plant. Wetlands and wetland edges as a specimen plant with a pleasing multi-stemmed vase-shape.

Most reproduction is vegetative (Lonard et al. 2015). Plant in coastal wetlands on upslope side of mangrove swamps.

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.

Climbs by twining. Train on a fence or arbor, allow to climb trees. Can be used as a groundcover but does not bloom well with that use.

Not salt tolerant of inundation by salty or brackish water. Low/no tolerance of salty wind or direct salt spray

Fruits are showy from mid-distance until spring. Salt tolerance is unknown but given known locations for the plant, we assume it is likely to be low. Specimen or hedge plant.

Low growing groundcover. Can be used as a turf substitute in low traffic areas.
