Description
Photograph of a specimen of an annual sunflower, [s.d.]. Three flowers are visible on the branch. On a neutral background. "These are hardy herbaceous perennials or annuals found wild in North America. They produce large yellow flowers in late summer and autumn. The perennial kinds are tall and vigorous. H. decapetalus multiflorus and its double variety, Soliel d'Or, grow 4 to 5 feet high. The prettiest one is called Monarch it is a variety of H. atrorubens sparsifolius. This plant will grow 6 to 7 feet high and bear large, golden yellow blooms. All of the perennial kinds have yellow blossoms. H. argyrophyllus, the Silverleaf Sunflower is an annual kind that grows about 6 feet high. Its leaves are clothed with silky, soft hairs, which give them a distinctly silvery appearance. It produces many yellow flowers, 3 inches in diameter that have dark brown-purple centers. H. annuus is an annual commonly known as the Sunflower. It grows 6 to 10 feet high and produces huge, black centered flowers. There are varieties of the Sunflower with different colored flowers. Some are reddish, pale or deep yellow. The largest is the variety Russian Giant." -- unknown author (part 1 of 2). "The seeds of the Sunflower are rich in oil the best kinds contain 28 or 30 percent. When cold pressed, this oil is useful as a salad oil, for cooking and for the manufacture of margarine. The seeds are also used for bird food for poultry and parrots and other caged birds. H. tuberosus, also known as the Sunchoke, Jerusalem Artichoke, or Girasole, is a hardy perennial grown for its edible tubers. As you can see, the Jersalem Artichoke is a relative of the Sunflower, not the Globe Artichoke (see, Cynara). This is a vigorous, enduring, versatile plant, which will grow up to 6 feet high in sunny, dry locations and much taller in fertile soil and partial shade. It produces yellow flowers with dark centers that are filled with small seeds, which birds love. They spread quickly and can become a nuisance. The Jerusalem artichoke is usually grown in the far corner of the garden because they aren't very pretty looking. The texture of the tubers is much like early potatoes, but they have a slightly sweeter taste. They can be eaten raw or cooked like potatoes. The tubers contain insulin, a carbohydrate that diabetics can digest." -- unknown author (part 2 of 2).
