I was cleaning up my overgrown rose bed and noticed that this "weed" I've been pulling up has little pods on it, similar to a green bean. Some of the pods are green and others are black and dry (maybe those are dead or diseased, I don't know). These vines have been there all spring, just climbing up the roses and no matter how many I pull up they keep coming back. Now that I see they have pods on them I am curious about what they are and if they are edible. I just moved into my house a few months ago so they may have been planted by the previous owner or they may be wild. It seems strange that they would plant beans in a rose garden though. Does anyone recognize this plant? I would appreciate any input!
