Someone gave me many seed pods for Purple Hyancinth bean vine. Thinking that not all would seed, I threw them Everywhere!! All around every fence, in many of my potted plants and I think that every single pod has seeded, so now I am having to run around transplanting out of my potted plants. If I leave the hundreds growing along my fence lines will they take over or are they easy to control? These seeds are insane! I planted them barely 3 weeks ago and many are already 40 inches long, Incredible!
