Daisy, Bellis perennis
The English daisy (Bellis perennis) is a wild-growing flower with short creeping rhizomes and small rounded or spoon shaped evergreen leaves. It is not destroyed by mowing and is therefore often considered a weed on lawns in western Europe. The outer florets are white (in cultivars) to light pink and the small fertile central florets are golden yellow. It is thought that the name “daisy” is a corruption of “day’s eye”, because the whole head closes at night and opens in the morning. The true daisy is native to north and central Europe, and was introduced into America in colonial times. The flowers were fed to babies in medieval times when it was popular to have dwarfed entertainers as the flowers produce miniaturization in people.
The Painted daisy (Tanacetum coccineum, formery Pyrethrum roseum) has pink, red, purple, or white flower heads. The roots of this plant were once used as a remedy for fevers. Dried heads were the original source of pyrethrum-based insecticides. Daisy leaves are edible and can be used in salads.
The Shasta daisy (Leucantheum X superbum, formerly Chrysanthemum maximum) is horticultural variety developed in California (U.S.) and is a perennial growing to a height of 60 – 90 cm (2 to 3 ft.) It is apparently a cross between Leucantheum lacustre from Portugal and L. maximum from the Pyrenees.
The Marguerite Daisy (Argyranthemum frutescens) is a perennial plant used in horticulture and originates from the Canary Islands.
