Aster

You will find garden asters in many sizes and colors. Flowers usually bloom in late summer or fall in clusters, with each blossom from half an inch to several inches wide, on stems six inches to several feet tall. Ray petals are white, blue, deep purple, or pink, and central disks are golden. Many asters are North American natives and grow in wayside places with no care at all.
