A floral boy name from Greek mythology, Hyacinthus was a Spartan youth accidentally killed by Apollo, from whose blood sprang a beautiful and fragrant flower. Also spelled as Hyakinthos, the name was also borne by a 3rd century saint and has seen more use via its international forms: French Hyacinthe and Spanish Jacinto.
