Bellis perennis sis a common European species of daisy, of the Asteraceae family, often considered the archetypal species of that name. Many related plants also share the name "daisy", so to distinguish this species from other daisies it is sometimes qualified as common daisy, lawn daisy or English daisy. Historically, it has also been commonly known as bruisewort and occasionally woundwort (although the common name woundwort is now more closely associated with Stachys (woundworts)). Bellis perennis is native to western, central and northern Europe, but widely naturalized in most temperate regions including the Americas and Australasia.
DescriptionIt 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 pseudonymous, 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 capitulate, or disc of florets, is surrounded by two rows of green bracts known as "phylacteries".

B. perennials 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 naturalized).
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 colors (red, pink & white). They are generally grown from seed as biennial bedding plants. They can also be purchased as plugs in Spring. The cultivator assort series has gained the Royal Horticultural Society's Award of Garden Merit.
