Daisy

Daisy (Bellis perennis) Is a garden perennial plant belonging to the family Asteraceae.

It is native to Europe and Asia and a common wild plant in the United States.

Daisies are unusual. A "Daisy flower" is actually made up of two types of flowers: the center of the daisy flower is a collection of disk flowers. 

And the petals are individual ray flowers. Each disk flower is an individual flower made up of a stamen, carpel and ovary. the ray flowers, however, are sterile. The disk flowers are yellow. The ray flowers are white or purple.

The plant has leafless flower stalks and is hairy below the flower.

Daisies can be used as food, as medicine or to know if somebody loves you :-)
