This is great!blue sweet pea, chickling vetch, Indian pea, Indian vetch, white vetch.
I know sweet peas are flowers and I've always liked that name: I'll have to check this one out....My blue sweet peas are flowers. Could the pods they (eventually) produce be edible??
Beautiful! Unfortunately mine aren't that azure. I'll try nibbling the flowers. They eat virtually anything that grows out of the ground here!
