What are the edible species that fill our ecosystems in autumn? Herbs, greens, roots, nuts, seeds, and mushrooms are all in season at the same time now. Proceeding a foraging tour of the Appalachian Trail, I'll bring in dozens of regional edibles for you to see, touch, taste, and discuss. You'll experience delicious leafy greens such as wood sorrel and sheep sorrel, Asiatic dayflower, lady's thumb, field garlic, and garlic mustard. You may also get to sample wintergreen-flavored black birch,sassafras, the original source of root beer, and many other species.
