Magic beans

I have no idea what kind of beans these are, or what to do with them. The little girl across the street brought one little plant home from school, and asked Kevin to plant it in our garden. He did and has been watching over it for a couple of months. The pods are almost a foot long...and the beans are red...and quite large. Whatever they are...the blossoms are beautiful, and the beans are plentiful. We are drying the seeds to plant next year. Perhaps by then we will know what to do with them.
