I only had 2 beans on 8' of huge plants! I have eaten this bean and it is wonderful. The one I grew even stayed purple when cooked and was so sweet. I'd love to get more seeds and give them a try again! I think it is originally from Thailand, but was unable to locate it on our recent trip there.I have bought the fresh beans at our local Farmer's Market from a Laotian farmer. Mary-Anne
