Hyacinths are spring-flowering bulbs with long, narrow leaves that are folded lengthwise. Hyacinths are highly fragrant flowers that bloom in dense clusters. Hyacinth is the common name for approximately 30 perennial flowering plants of the genus Hyacinthus (order Liliales, family Liliaceae) of the Mediterranean region and Africa. The common Hyacinth (Hyacinthus Orientalis), whose flowers open fully and look like little starfishes, should not be confused with the common grape Hyacinth flowers (Muscari Botryoides). The common grape Hyacinth bears tight blooms in a raceme resembling clusters of grapes. Both are spring-blooming bulb plants.
