Edible Wild Plants of Eastern North America: Identifying and Using the Edible Wild Plants of the Eastern United States and Eastern Canada, first published in 1943, was a landmark book in terms of its thoroughness (covering nearly 1000 plant species, plus poisonous plants, mushrooms, seaweeds and lichens) and its detailed descriptions of each plant and their uses. This extensively revised (2020) full-color edition updates each plant's scientific name, adds distribution maps for many species, includes new information, and all new illustrations. Also added are cautionary notes for plants once considered safe to eat but which are now considered dangerous if eaten or improperly prepared. Separate chapters cover poisonous plants, edible plants, edible and poisonous mushrooms, and edible seaweeds and lichens.
