Daisy (Bellis perennis) 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. 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. 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.
