Wild Sunflower.Helianthus tuberosus.Jerusalem Artichoke.
Found through September and October, in cultivated fields, and along thicket borders.
The stalk branches for flowers near the top; it is leafy, large, from 3 to 7 or 8 feet, very stout, and rough with short hairs. Its color is light green.
The leaf is large, and oval, with a pointed tip and widest at the base, where it tapers into a short stem; the margin is somewhat obscurely notched, the texture is coarse, showing 3 strong ribs, and the surface is rough. The color is a full, strong green. In growth, the leaves are generally opposite, though the upper leaves are often alternate.
The disc flowers are small, tubular, and 5-pointed, of a dull yellow color; the stamens are protruding, spirally curled, and brownish; the rays, from 8 to 15 in number, are long, and broad, and colored a brilliant orange-yellow. The leafy cup, which encloses the head, is composed of several rows of green parts; the heads grow singly from the summit of the stalk, or by twos and threes, on stems, from the angles of the leaves. This is a towering plant, whose brilliant flowers and vigorous leafage render it an effective feature of the wild hedgerow. Its tuberous root is sometimes cooked as a vegetable, and in a raw state is eaten by men and boys.
