SUNFLOWER . The See also:

common sunflower, known botanically as Helianthus annuus, a member of the natural See also:order See also:Compositae, is a native of the western See also:United States. It is an See also:annual See also:herb with a rough hairy See also:stem 3 to 12 ft. high, broad coarsely toothed rough leaves 3• to 12 in, See also:long, and heads of See also:flowers 3 to 6 in. wide in See also:wild specimens and often a See also:foot or more in cultivated. See also:Double forms are in cultivation, one (globosus fistulosus) having very large globular heads. The plant is valuable from an economic as well as from an ornamental point of view. The leaves are used as See also:fodder, the flowers yield a yellow dye, and the seeds contain oil and are used for See also:food. It is cultivated in See also:Russia and other parts of See also:Europe, in See also:Egypt and See also:India and in several parts of See also:England hundreds of See also:plants are grown on sewage farms for the seeds. The yellow sweet oil obtained by See also:compression from the seeds is considered equal to See also:olive or See also:almond oil for table use. Sunflower oilcake is used for stock and poultry feeding; and largely exported by Russia to See also:Denmark, See also:Sweden and elsewhere. The genus Helianthus contains about fifty See also:species, chiefly natives of See also:North See also:America, a few being found in See also:Peru and See also:Chile. They are tall, See also:hardy annual or perennial herbs, several of which are well known in gardens where they are of easy cultivation in moderately See also:good See also:soil. H. decapetalus is a perennial about 5 ft. high with solitary heads about 2 in. across in slender twiggy branchlets; H. mulliftorus is a beautiful species with several handsome double varieties; H. orygalis is a graceful perennial 6 to to ft. high, with drooping See also:willow-like leaves and numerous comparativelysmall yellow See also:flower-heads.

H. atrorubens, better known as Harpaliuin rigidum, is a smaller plant, 2 to 3 ft. high, the flower heads of which have a dark red or See also:

purple disk and yellow rays. There are many See also:fine forms of this now, some of which grow 6 to 9 ft. high and have much larger and finer flowers than the type. Other fine species are H. giganteus, to to 12 ft.; H. laetiflorus, 6 to 8 ft., and H. mollis, 3 to 5 ft. H. tuberoses is the See also:Jerusalem See also:artichoke. Since the word " sunflower," or something corresponding to it, existed in See also:English literature before the introduction of Helianthus annuus, or, at any See also:rate, before its See also:general See also:diffusion in English gardens, it is obvious that some other flower must have been intended. The See also:marigold (Calendula officinalis) is considered by Dr See also:Prior to have been the plant intended by See also:Ovid (Met. iv. 269–270) " . Ilia suum, quai,mvis radice tenetur, Vertitur ad solem; mutataque servat amorem " and likewise the solsaece of the Anglo-Saxon, a word See also:equivalent to solsequium (See also:sun-following). But this See also:movement with the sun is more imaginary than real, the better explanation for the application of the name to a flower being afforded by the re-semblance to " the radiant beams of the sun," as See also:Gerard expresses it. The See also:rock-See also:rose (Helianthemum vulgare) was also termed sunflower in some of the herbals from its flowers opening only in the See also:sunshine. Actinella grandiflora, a See also:pretty perennial 6 to 9 in. high, from the See also:Colorado mountains, is known as the Pigmy sunflower.
