Binomial name

Bellis perennis

The English daisy (Bellis perennis) is a wild flower with short creeping rhizomes and small rounded or spoon shaped evergreen leaves. It is not destroyed by mowing and is therefore often a weed in lawns in western Europe. The outer florets are white to (in cultivars) 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. This, the true daisy, is native to north and central Europe, and was introduced into America in colonial times.

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.

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 Transvaal daisy (Gerbera jamesonii) is native to South Africa. This plant is known as Barberton daisy in England. Considered the most decorative of all daisies, some cultivars bear flower heads as much as 30 cm (12 in) across. Florist's gerberas are usually a cross between G. jamesonii and G. viridifolia.
