I suggest the Greek hero Ὑάκινθος, mostly transcribed Hyacinth. The important Spartan festival Hyacinthia (Ὑακίνθια) is based upon this mythological persona.
Hyacinth was one of Apollo's lovers. He was tragically killed by Apollo, but "revived" afterwards as a flower. This flower was regarded as the most beautiful flower in Ancient Greek Culture. The concept of decay and renewal (Spring) is linked to this hero and the flower named after him.
