Bellis perennis

Description

It is an herbaceous perennial plant with short creeping rhizomes and rosettes of small rounded or spoon-shaped leaves that are from 3/4 to 2 inches (approx. 2–5 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'. Wherever it appears it is often considered an invasive weed.

The flowerheads are composite, in the form of a pseudanthium, consisting of many sessile flowers about 3/4 to 1-1/4 in (approx. 2–3 cm) in diameter, with white ray florets (often tipped red) and yellow disc florets. Each inflorescence is borne on single leafless stems 3/4 - 4 in (approx. 2–10 cm), rarely 6 in (approx. 15 cm) tall. The capitulum, or disc of florets, is surrounded by two rows of green bracts known as "phyllaries".

Cultivation

B. perennis generally blooms from early to midsummer, although when grown under ideal conditions, they have a very long flowering season and will even produce a few flowers in the middle of mild winters.

It can generally be grown in USDA Zones 4 - 8 (i.e. where minimum temperatures are above −30 °F (−34 °C)) in full sun to partial shade conditions, and requires low or no maintenance. It has no known serious insect or disease problems and can generally be grown in most well-drained soils. The plant may be propagated either by seed after the last frost, or by division after flowering.

Though invasive, the species is still considered a valuable ground cover in certain garden settings (e.g., as part of English or cottage inspired gardens, as well as spring meadows where low growth and some color is desired in parallel with minimal care and maintenance while helping to crowd out noxious weeds once established and naturalised).

Numerous single- and double-flowered varieties are in cultivation, producing flat or spherical blooms in a range of sizes (1 cm to 6 cm) and colours (red, pink & white). They are generally grown from seed as biennial bedding plants. They can also be purchased as plugs in Spring. The cultivar 'Tasso series' has gained the Royal Horticultural Society's Award of Garden Merit.

Etymology

Bellis is Latin for "pretty" and perennis is Latin for "everlasting".

The name "daisy" is considered a corruption of "day's eye", because the whole head closes at night and opens in the morning. Chaucer called it "eye of the day". In Medieval times, Bellis perennis or the English Daisy was commonly known as "Mary's Rose".

The English Daisy is also considered to be a flower of children and innocence.

Daisy is used as a girl's name and as a nickname for girls named Margaret, after the French name for the oxeye daisy, marguerite.

Culinary

This daisy may be used as a potherb. Young leaves can be eaten raw in salads or cooked, noting that the leaves become increasingly astringent with age. Flower buds and petals can be eaten raw in sandwiches, soups and salads. It is also used as a tea and as a vitamin supplement.

Herbal medicine

Bellis perennis has astringent properties and has been used in herbal medicine. In ancient Rome, the surgeons who accompanied Roman legions into battle would order their slaves to pick sacks full of daisies in order to extract their juice, hence the origin of this plant's scientific name in Latin. Bandages were soaked in this juice and would then be used to bind sword and spear cuts.

Bellis perennis is still used in homeopathy for wounds and after certain surgical procedures, as well as for blunt trauma in animals. Typically, the plant is harvested while in flower when intended for use in homeopathy.

Bellis perennis flowers have been used in the traditional Austrian medicine internally as tea (or the leaves as a salad) for treatment of disorders of the gastrointestinal and respiratory tract.

Other uses

Daisies have traditionally been used for making daisy chains in children's games.
