A tall perennial species, with a rough, hairy, purple-stained stalk rising from three to twelve feet high from fleshy, creeping, edible roots, and are either single or branching at the top. The firm-textured, taper-pointed, lance-shaped leaves are very rough above, and rough hairy beneath. They are narrowed at the base, and are set on short stems or clasp the stalk. The margins are finely toothed or entire. Many or all of the upper leaves are alternate, but sometimes they all are paired. Usually several flower heads are borne on long, terminal stems, and are often two and a half inches broad. The yellowish disc florets are surrounded with from ten to twenty pale yellow rays, and are held together in a deep green, half round cup. This Sunflower is found in low thickets, swamps, and wet meadows from August to October, from Maine and Ontario to the Northwest Territory, and south to Florida, Nebraska and Louisiana. A more northern variety of this species develops tuberous roots, and because they are used as food by the Indians, they are known as Indian potatoes.
