here in middle TN i've found growing along my chain link fence a tall (about 5-6 feet) vining monster that has leaves that look very like a large bean leaf. now it has pods on it that are very hard, kind of like a milkweed pod and about 2-3 inches long. any flowers that may have been on it at some time must be insignificant as i've not seen much of anything other than a tiny cross thing. i don't have a picture but hope you can ID it for me. seems i remember the pods come apart in the fall like a milkweed too but it looks exactly like a huge bean leaf (leaves are about 5 inches long-4 inches wide. thanks for any help.
