Narcissus jonquilla, commonly known as jonquil[3] or rush daffodil, is a bulbous flowering plant, a species of the genus Narcissus (daffodil) that is native to Spain and Portugal but has now become naturalised in many other regions: France, Italy, Turkey, the former Yugoslavia, Madeira, British Columbia in Canada, Utah, Illinois, Minnesota, Ohio, and the southeastern United States from Texas to Maryland.

Narcissus jonquilla bears long, narrow, rush-like leaves (hence the name jonquil, Spanish junquillo, from the Latin juncus 'rush').

[4][5] In late spring it bears heads of up to five scented yellow or white flowers.

It is a parent of numerous varieties within Division 7 of the horticultural classification.

[6] Division 7 in the Royal Horticultural Society classification of Narcissus includes N. jonquilla and N. apodanthus hybrids and cultivars that show clear characteristics of those two species.
