Hello My brother in Montreal found this growing down the side of his house. Is it just a "volunteer" edible bean? Thank you Ken
Could be something from Apocinaceae. Check Cynanchum rossicum, for example. Look inside the pod. I bet, it has hairy seeds. Hardly edible, some may be toxic.
Thank you! Yes, "Pale swallow-wort" looks exactly like it!!! I'll ask him to open a pod and check the seeds....and wash his hands. :-) Ken
