Last year (2020) out of haste and inexperience, I planted a wide variety of dry beans from my pantry... kidney beans included. Later that season, I found out the kidney bean pods were toxic to eat, so I dried the whole lot (as I couldn't tell them apart until dried). Now this season I only planted green beans (in the same location), buuut, someone said kidney beans can grow back on their own, are my green beans ruined again? Is it possible for the plants to regrow and now I have kidney beans masquerading as green beans?
