The hyacinthThe hyacinth is a spring-flowering bulb plant of the lily family.

Most American varieties of hyacinth were developed from the common hyacinth, which grows from 12 to 18 inches (30 to 45 cm) high. The common hyacinth has a large bulb and four to six narrow, straplike leaves. Its fragrant, bell-shaped flowers grow in cylindrical clusters at the tops of smooth, hollow stems. Hyacinths may be white, yellow, pink, red, blue, or purple.

Hyacinths may be grown indoors in moist earth or loam, or in water. The flowers are often forced (grown out of season) in greenhouses by florists. Outdoors, the bulbs are planted in the fall and are lightly covered with mulch to protect the young shoots against freezing in early spring.

The common hyacinth is Hyacinthus orientalis of the family Liliaceae.
