Abstract
The common sunflower, Helianthus annuus, L. is a member of the Compositae and a native of the Great Plains region of the United States. It is an annual herb, with a rough hairy stem three to fifteen feet high, broad, coarsely toothed rough heartshaped leaves three to twelve inches long and heads of flowers three to six inches wide in wild specimens and often one foot or more in cultivated plants. The plant is economically important, for its leaves are used as fodder, the flowers yield a yellow dye, and the seeds contain oil and are used for food. It is cultivated in Russia, England and other parts of Europe, in Egypt and in India for the seeds, the yellow sweet oil obtained by their compression being considered equal to olive or almond oil for table use. The achenes have also been used by the American aborigines for food, and are the main resource of many western seed eating animals and birds. According to Americana, they are a ’’tidbit for the Tarters”. Sunflower oil cake is used for stock and poultry feeding, and is exported by Russia to Denmark, Sweden and other neighboring countries.
