Trying to identify for a friend

I’m trying to help someone identify a plant….. Here is her description of it….

my folks have one growing at the deck railing every year, It will get pretty little white-ish with a tint of purple flowers, then they will turn into a dark purple bean pod. Each pod will have 2 to 3 “beans” the beans will be a almost black with a white spot. Im not sure if it’s edible, we always called it the purple bean vine

This is a hyacinth bean. They are generally regarded as toxic, although, there is a special preparation method that will render them edible. I would not advise this if you have not had experience with this bean before.
