Sorry everyone. I posted about Lablab hyacinth bean vine in 2014 and apparently lost my "link" to the website. I still have the seeds since this last summer produced a nice 'crop'! I believe young tender pods are indeed edible. It is only after they dry out do they become poisonous. I have always heard that it's a food crop in Eastern Asia. Or was at some point. Our Italian greyhound and German shepherd never ate them to my knowledge. Please contact me if you want any.

Oh... those are hyacinth bean vines in the back of the garden in the photo.
