Hyacinthus /ˌhaɪəˈsɪnθəs/[1] is a small genus of bulbous herbs, spring-blooming perennials.[2][3] They are fragrant flowering plants in the family Asparagaceae, subfamily Scilloideae[4] and are commonly called hyacinths (/ˈhaɪəsɪnθs/). The genus is native predominantly to the Eastern Mediterranean region from the south of Turkey to the Palestine region, although naturalized more widely.[5]
Several species of Brodiaea, Scilla, and other plants that were formerly classified in the Liliaceae family and have flower clusters borne along the stalk also have common names with the word "hyacinth" in them. Hyacinths should also not be confused with the genus Muscari, which are commonly known as grape hyacinths.
Hyacinthus grows from bulbs, each producing around four to six narrow untoothed leaves and one to three spikes or racemes of flowers. In the wild species, the flowers are widely spaced, with as few as two per raceme in H. litwinovii and typically six to eight in H. orientalis which grows to a height of 15–20 cm (6–8 in). Cultivars of H. orientalis have much denser flower spikes and are generally more robust.[6]
The genus name Hyacinthus was attributed to Joseph Pitton de Tournefort when used by Carl Linnaeus in 1753.[5] It is derived from a Greek name used for a plant by Homer, ὑάκινθος (hyákinthos), the flowers supposedly having grown up from the blood of a youth of this name killed by the god Zephyr out of jealousy.[7] The original wild plant known as hyakinthos to Homer has been identified with Scilla bifolia,[8] among other possibilities. Linnaeus defined the genus Hyacinthus widely to include species now placed in other genera of the subfamily Scilloideae, such as Muscari (e.g. his Hyacinthus botryoides)[9] and Hyacinthoides (e.g. his Hyacinthus non-scriptus).[10]
Hyacinthus was formerly the type genus of the separate family Hyacinthaceae; prior to that, the genus was placed in the lily family Liliaceae.[11]
Some authorities place H. litwonovii and H. transcaspicus in the related genus Hyacinthella,[13] which would make Hyacinthus a monotypic genus.
