DAISY, the name applied to the plants constituting the genus Bellis, of the family Compositae.
It is derived from the Anglo Saxon and means day's eye. The genus contains ten species found in Europe and the Mediterranean region. The common daisy, B.
perennis, is the only representa tive of the genus in the British Isles. It is a perennial, abundant everywhere in pastures, lawns and on banks in Europe, except in the most northerly regions, and in Asia Minor, and occurs as an introduced plant in North America. The stem of the daisy is short; the leaves, which are numerous and form a rosette, are slightly hairy, obovate-spatu late in shape, with rounded teeth on the margin in the upper part ; and the root-stock is creeping, and of a brownish colour. The flowers are to be found from March to November, and occa sionally in the winter months. The heads of flowers are solitary, the outer or ray-florets pink or white, the disk-florets bright yel low. The size and luxuriance of the plant are much affected by the nature of the soil in which it grows. The cultivated varieties, which are numerous, bear finely-coloured flowers, and make very effective borders for walks. What is known as the "hen-and chicken" daisy has the main head surrounded by a brood of some times as many as ten or twelve small heads, formed in the axils of the scales of the involucre. The ray-florets curve inwards and "close" the flower-head in dull weather and towards evening. To the farmer the daisy is a weed; it exhausts the soil and is not eaten by any kind of stock.
In French the daisy is termed la marguerite, and "herb mar garet" is stated to be an old English appellation for it. In Scot land it is popularly called the gowan, and in Yorkshire it is the bairnwort, or flower beloved by children. The Christmas and Michaelmas daisies are species of Aster; the oxeye daisy is Chry santhemum Leucanthemum, a common weed in meadows and waste places. B. perennis flore-pleno, the double daisy, consists of dwarf, showy, 3 to 4 in. plants, flowering freely in spring if grown in rich light soil.
