The sunflowers are mostly large, erect, perennial herbs, with the flowers characteristic of the order Compositae. They are natives of tropical America, but have become widely distributed in cultivation, appreciated on account of their large yellow flowers. They not only thrive very luxuriantly under cultivation, but spread very quickly spontaneously. Every one is familiar with the sunflower as it appears in cultivation, hence no special description shall be given of it. It is kin to the iron weed, the dandelion, the golden rods, the asters and the daisies. It would be impracticable to describe or mention all the species and varieties of sunflowers and their numerous relatives. We shall refer very briefly to a few of the more common kinds. Helianthus annuus is a commonly cultivated species. The seeds of this plant furnish a very useful oil; the flowers yield honey and a useful dye; the stalks a textile fabric and the leaves fodder. The seeds of this and other species are also used as food, and as a surrogate for coffee. The carefully dried and prepared leaves have been used as a substitute for tobacco in cigars. Poultry eat the seeds very greedily and thrive well upon them, due to the oil present. It is also maintained that a large number of sunflowers about a dwelling place will serve as a protection against malaria. An infusion of the stem is said to be anti-malarial. H. tuberosus, known as the Jerusalem artichoke, has large tuberous roots which are sometimes eaten when cooked or pickled. Several species are said to have decided medicinal properties. H. odora is said to be carminative, diuretic, stimulant and antemetic. H. rigida is tonic and astringent. H. virgaurea of both continents is also astringent and tonic. In the eclectic school of medicine the infusion of seeds is used as a mild expectorant, and the expressed oil as a diuretic. The diuretic properties are said to be due to nitre, which occurs most plentifully in the central pith of the stalks. The medicinal virtues of the sunflowers are very limited and uncertain. Their principal use is that of a showy garden plant. That they check or prevent malaria is quite probable, because of their draining effect upon the soil rather than any medicinal property residing in the plants themselves. The daisies, of which the ox-eye daisy is a well-known example, are garden and field favorites. As already indicated, they are kin to the sunflowers. The word daisy is a contraction of the old English words "dayes eye," that is, the eye of day, meaning the sun, as indicated in the verse from Chaucer. There are a great many flowers known as daisies and again a given one has a number of popular names. For instance, Rudbeckia hirta (see illustration) is variously designated yellow daisy, black-eyed Susan, nigger head, golden Jerusalem and ox-eye daisy.
