Other forms: asters

An aster is a flower that's related to the daisy. Asters tend to bloom in the late summer or early fall, and they come in many different colors.

If you plant asters in the spring, you'll be rewarded with purple and pink blossoms a few months later. Asters are perennial plants, so they continue to grow and bloom again year after year. There are hundreds of different varieties of asters, but most of them have small, daisy-like flower heads, almost star shaped — which is why the plant is called aster, the Latin word for "star."
