Daisy. Bellis perennis, the daisy, is a European species of the family Asteraceae, often considered the archetypal species of the name daisy.
To distinguish this species from other plants known as daisies, it is sometimes qualified as common daisy, lawn daisy or English daisy. Bellis perennis is a perennial herbaceous plant growing to 20 centimetres in height.
It has short creeping rhizomes and rosettes of small rounded or spoon-shaped leaves that are from 2 to 5 cm long and grow flat to the ground. The species habitually colonises lawns, and is difficult to eradicate by mowing, hence the term 'lawn daisy'.
It blooms from March to September and exhibits the phenomenon of heliotropism, in which the flowers follow the position of the sun in the sky. The flowerheads are composite, about 2 to 3 cm in diameter, in the form of a pseudanthium, consisting of many sessile flowers with white ray florets and yellow disc florets.
Each inflorescence is borne on a single leafless stem 2 to 10 cm, rarely 15 cm tall. The capitulum, or disc of florets, is surrounded by two rows of green bracts known as phyllaries. The achenes are without pappus. Bellis may come from bellus, Latin for pretty, and perennis is Latin for everlasting. The name daisy, possibly originating with this plant, is considered a corruption of day's eye, because the whole head closes at night and opens in the morning. Geoffrey Chauc
