Thanks Wayne ( and R Scott, and everyone else), that looks pretty close.

Partridge pea is considered an excellent
species for planting on disturbed areas for erosion
control and improving soil fertility. It establishes
rapidly, fixes nitrogen, reseeds, and slowly decreases
as other species in the seeding mix begin to dominate
the site. Nitrogen fixation is greatest during the
flowering stage
Sounds like Cattle can get sick if they eat lots of it. Anyone know if it bothers sheep or ducks (Have ducks, wife wants sheep)? Other than that, it sounds like a great cover crop.
