Purple Hyacinth Vine or Hyacinth Bean Vine

Several years ago while walking in the neighborhood I found this vine. I purloined a few seeds and the next spring planted some in my yard. For several years(sometimes skipping a year) I would plant the seeds and always a beautiful vine. The color that interests me is purple and in the photo I tried to show purple flowers, purple seed pods, and purple veins in the leaves. The seeds even have a little purple when they first come out of the pod. This vine was one of Thomas Jefferson's favorites. The seeds are poisonous until cooked, edible but not so good.
