Amorpha herbacea var. crenulata, a semi-deciduous shrub, has several flower spikes that range in color from white and orange to blue and purple. The small, dark green leaflets are numerous (25-35) on a reddish branch. Amorpha herbacea var. crenulata is known from the Miami Rock Ridge Pinelands, an extremely rare and threatened ecosystem which contains over 40 endemic species (USFWS 1988).
Distribution & Occurrence
Amorpha herbacea var. crenulata can be found in several habitats: in pine rocklands, pinelands and hammock edges (Wilbur 1964, USFWS 1988), vacant lots, marl prairie, fire-maintained areas (Coile 2000). Historically, this species has also been seen in the edges of wet prairies in Dade County (Kernan 1995, 1999). Communities associated with seasonally hydrated soils and frequent burning (USFWS 1988, Abrams and Hulbert 1987, Tester 1996). This species can tolerate varying light conditions, soil depth, and litter depth (Papanastasis et al. 1997, 1998).
