This is a part of a confusing group with unstable taxonomy; this species was listed as Galactia regularis in Wunderlin & Hansen (2011) and for several years on the Atlas of Florida Vascular Plants. Plants in the Florida Keys and in the pine rocklands of Miami-Dade County are the closely related Galactia parvifolia, with narrow leaflets. For any Galactia species, we recommend using plants that were originally collected from near your project location.
