Well, I can't tell you how many flowers are in the photo, because I am too lazy to count them all. I can tell you that there are hundreds.

This flower, Echinacea, is a member of the family Asteraceae, which are composite flowers. Each of the structures that looks like a flower is actually an inflorescence (flower cluster), made up of many examples of two different kinds of flowers. Each of the things that looks like a petal is actually a ray flower. In the center, each of the small, structures is a disk flower.

Asteraceae is one of the largest families of plants, including sunflowers, dandelions, thistles, marigolds, sinnias, daisies, asters, chrysanthemums, and more than 20,000 other species.
