Peony

The wild peony (Paeonia mascula) only blooms once a year, in late spring, and only for one week. But the stunning flowers and dark yellow stamens make it worth the wait.
In Greek mythology, Paeon was the physician to the gods who angered his teacher Asclepius after he extracted a milky liquid from the root of a peony that cured Pluto. Asclepius was the god of medicine and healing. He threatened to kill Paeon out of jealousy because he was outsmarting his teacher. Zeus saved him by turning him into a beautiful peony.

Whatever the origin.. It's beautiful
