]] Narcissus is a genus of predominantly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common names including daffodil, daffadowndilly, narcissus, and jonquil are used to describe all or some members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by a cup- or trumpet-shaped corona. The flowers are generally white or yellow (orange or pink in garden varieties), with either uniform or contrasting coloured tepals and corona.
