Jonquil, a perennial flowering herbaceous plant native to southern Europe and northern Africa. It is grown as a garden plant and for its fragrant flowers, which yield an oil that is used in soaps and perfumes. The trumpet-shaped yellow flowers grow in clusters of two to six at the tops of the stems. Glossy, dark-green leaves grow at the base of the stems. The common jonquil grows to 18 inches (46 cm) in height and is a popular garden plant in the United States. The Campernelle jonquil, which reaches a height of 12 inches (30 cm), is grown chiefly in Spain and France.

The daffodil, a related plant, is sometimes called jonquil.

The common jonquil is Narcissus jonquilla; Campernelle, N. odorus. Jonquils belong to the amaryllis family, Amaryllidaceae.
