Wikijunior:Summer Flowers of Northern New England/Erigeron annuus
This daisy has fine, white, thread-like rays shooting out of the yellow disk in the center. If you look closely at the yellow disk, you will see that the disk itself is made of more tiny little flowers. Any flower that does this is a member of the Aster family. The whole flower is about a half inch across, but the plant can grow over four feet tall. Are you taller than a Daisy Fleabane?
