Greenbrier, Smilax rotundifolia. Ive been eating this plant for years. PULL on the new tips and they will break off in the right place much like asparagus will when you bend it. Raw, they taste a little like a green bean. They can be eaten raw or cooked. We eat them as we hike, etc. They are better when about 6" or under. All parts are edible including the berries. It also has valuable medicinal properties and can be used for weaving, fish hooks, light use cordage, wildlife barriers around gardens, and to make biochar. Grows abundantly in most areas of eastern North America.
