Hi
My first thoughts are hyacinth bean vine.
Steve

Hi, I agree with Steveg, Hyacinth bean vine, Dolichos Lablab, it's an annual plant, which means you will have to plant seeds, where you want them to grow, every year, one and a half inches deep, when all risk of frost is past in your area, don't know where you are in U S A, you may not get frost, it can grow 10 to 15 ft in 1 season, and then die, Derek.

Thanks a bunch. That is what it is. I looked it up online.
