Mostly north and west.
Flowers: growing closely together on one side of a long spike. Calyx: short, with unequal teeth. Corolla: papilionaceous. Leaves: pinnate, divided into ten to twelve pairs of smooth, oblong leaflets. The common petiole terminating in a tendril, This "splendid tufted vetch," is found along the borders of roadsides and in the thickets. It stretches out its tendrils as though it loved to climb and gleefully throws out its bright flowers to mingle with the grasses and brambles.
V. Americana has larger purple flowers, and but five to seven pairs of ovate leaflets.
