Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common brands including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are being 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 usually white or yellow (orange or pink in garden varieties), with either uniform or contrasting colored tepals and corona.

Narcissus were popular in historic civilisation, both and botanically medicinally, but formally referred to by Linnaeus in his Kinds Plantarum (1753). The genus is normally considered to have about ten portions with around 50 species. The amount of varieties has assorted, depending on how they are labeled, scheduled to similarity between kinds and hybridization. The genus arose some time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise source of the name Narcissus is mysterious, but it is often associated with a Greek expression for intoxicated (narcotic) and the misconception of the young ones of this name who fell deeply in love with his own representation. The English word 'daffodil' appears to be derived from "asphodel", with which it was compared commonly.

The types are local to meadows and woods in southern Europe and North Africa with a centre of variety in the European Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were released in to the Far East to the tenth hundred years prior. Narcissi tend to be long-lived bulbs, which propagate by division, but are insect-pollinated also. Known pests, disorders and diseases include viruses, fungi, the larvae of flies, nematodes and mites. Some Narcissus species have become extinct, while some are threatened by increasing tourism and urbanisation.

Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe following the 16th hundred years and by the late 19th hundred years were an important commercial crop centred primarily on the Netherlands. Narcissi are popular as slash flowers so when ornamental plants in private and general population gardens today. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering a wide range of shapes and colours. Like other members with their family, narcissi produce a true number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested inadvertently. This property has been exploited for medicinal used in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in fine art and literature, narcissi are associated with a true number of themes in various cultures, ranging from fatality to good fortune, and as icons of spring and coil. The daffodil is the national rose of Wales and the icon of cancer charities in many countries. The looks of the untamed flowers in spring is associated with festivals in many places.

Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering for an underground storage light bulb. They regrow in the next calendar year from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf kinds such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may increase as large as 80 cm.

The crops are scapose, having an individual central leafless hollow blossom stem (scape). Several blue-green or green, narrow, strap-shaped leaves arise from the light. The plant stem bears a solitary flower, but once in a while a cluster of flowers (umbel). The bouquets, which can be conspicuous and white or yellowish usually, sometimes both or almost never green, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an external ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical shaped corona. The flowers may suspend down (pendent), or be erect. A couple of six pollen bearing stamens bordering a central style. The ovary is inferior (below the floral parts) consisting of three chambers (trilocular). The berry involves a dry capsule that splits (dehisces) launching numerous black seeds.

The bulb is placed dormant following the leaves and blossom stem die back and has contractile root base that pull it down further into the soil. The flower stem and leaves form in the light, to emerge the next season. Most varieties are dormant from summertime to late winter, flowering in the spring, though a few varieties are autumn flowering.
