Crocus

In Classical mythology, Crocus (Greek: Κρόκος) was a mortal youth who, because they were unhappy with his love affair with Smilax, was turned by the gods into a plant bearing his name, the crocus (saffron). Smilax is believed to have been given a similar fate and transformed into bindweed.
In another variation of the myth, Crocus was said to be a companion of Hermes and was accidentally killed by the god in a game of discus. Hermes was so distraught at this that he transformed Crocus' body into a flower.
