The September flower is the aster, which was named after the Greek word for "star" due to its star-shaped flower head. Asters bloom in the fall and have various meanings, including love, faith, and wisdom. They were used in ancient times for medicinal purposes and their blooming coincides with the feast of St. Michael, so they are also known as Michaelmas daisies. According to Greek mythology, asters grew where the tears of the goddess Astraea fell to earth during a great flood. Folklore also associated various magical properties with asters.
