Jewellweed or another name "Touch Me Nots": "The young shoots up to 6" can be cooked in 2 changes of water for 15 minutes and served as a cooked green". thats from my Petersens guide to wild edibles. I have it all around my yard but haven't tried it. It's one of those I know it's there in an emergency type foods. By the way, in the fall the tiny mature seed pods (look like miniature bean pods) really do explode nicely at the slightest disturbance. I like to carefully pick them and hand them to unsuspecting people and say the pods have "jumping bugs" inside. Scares the [email protected] out of em when they pop.
