Lawn daisy

It is an herbaceous perennial plant with short creeping rhizomes and small rounded or spoon-shaped rosettes of 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 3/4 to 1-1/4 in (approx. 2–3 cm) in diameter, with white ray florets (often tipped red) and yellow disc florets.

Although the 'flower' may appear to consist of a yellow centre with white petals, this is not the case. Each individual "petal" is itself an individual flower, called asterales. In the centre there are also many tiny yellow flowers. The different colours and styles of flower work together in order to attract insects. This type of flower is known as a composite flower. They are produced on leafless stems 3/4 - 4 in (approx. 2–10 cm), rarely 6 in (approx. 15 cm) tall.
Bellis perennis has astringent properties and has been used in herbal medicine.
