Lynn Landes, founder of the Wild Foodies of Philadelphia joins with  Chef Jeff Miller of  the eponymous catering company to forage for wild plants in the fields of the Weavers Way Coop farm at Awbury Arboretum. The plants, which Lynn doesn't like to call weeds although they are generally considered so, were to appear in the salad of a dinner that very evening to benefit the arboretum. Miller sampled some succulent-like purslane which he describes being crunchy and also some carpet weed which  your correspond concurs has a strong, mushroomy flavor. These, wood sorrel other "weeds" were all competing for purchase in the fertile soil where the farmers had planted onions for harvest months later. Landes takes the zealot's stance that only wild plants and animals, free for the taking are a sustainable source of food because agriculture of any kind requires ongoing maintenance. Watch video here.
