These beautiful and fragrant flowers are native to the Eastern Mediterranean from Turkey to Israel and Northeastern Iran. As pretty as they are, their bulbs are poisonous, containing oxalic acid which can irritate the skin.
The Hyacinth also has history in Greek Mythology. It was said that Hyacinth was a young boy loved by both Apollo and Zephyrus, the wind god. Hyacinth was throwing the discus with Apollo when he missed Apollo's throw and was struck by the discus and died. This was not accidental, though, for Zephyrus, being jealous of Apollo, caused a shift in the wind which forced Apollo's discus off course, thus causing Hyacinth's death. Apollo did not allow Hades to take Hyacinth, instead making him a flower.*
The hyacinth is sometimes associated with rebirth; maybe this is why.
