Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plants 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 known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by the cup- or trumpet-shaped corona. The bouquets are generally white or yellow (orange or pink in garden varieties), with either standard or contrasting coloured tepals and corona.

Narcissus were popular in ancient civilisation, both medicinally and botanically, but formally defined by Linnaeus in his Kinds Plantarum (1753). The genus is generally considered to have about ten portions with around 50 species. The true range of species has assorted, depending about how they are classified, anticipated to similarity between varieties and hybridization. The genus arose some right time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise origin of the true name Narcissus is unfamiliar, but it is linked to a Greek word for intoxicated (narcotic) and the myth of the young ones of this name who fell in love with his own representation. The English term 'daffodil' is apparently produced from "asphodel", with which it was compared commonly.

The types are local to meadows and woods in southern European countries and North Africa with a center of variety in the European Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were unveiled into the Far East to the tenth century prior. Narcissi have a tendency 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 initial times, but became increasingly popular in Europe after the 16th hundred years and by the later 19th century were an important commercial crop centred mostly on holland. Today narcissi are popular as slash plants as ornamental vegetation in private and public gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a variety of colours and shapes. Like other members of the family, narcissi create a number of different alkaloids, which provide some protection for the plant, but may be poisonous if accidentally ingested. This property has been exploited for medicinal used in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in literature and art work, narcissi are associated with a true number of themes in different cultures, ranging from death to fortune, and as icons of spring. The daffodil is the nationwide flower of Wales and the symbol of cancer tumor charities in many countries. The appearance of the wild flowers in spring and coil is associated with festivals in many places.

Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to an underground storage light. They regrow in the following year from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm with respect to the species. Dwarf types such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may expand as tall as 80 cm.

The vegetation are scapose, having an individual central leafless hollow blossom stem (scape). Several green or blue-green, thin, strap-shaped leaves come up from the bulb. The seed stem usually bears a solitary flower, but sometimes a cluster of blooms (umbel). The blooms, that are conspicuous and white or yellow usually, both or rarely renewable sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an external ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical shaped corona. The plants may hang up down (pendent), or be erect. A couple of six pollen bearing stamens encompassing a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The fruits contains a dried out capsule that splits (dehisces) launching numerous black seeds.

The bulb is dormant following the leaves and bloom stem die back and has contractile origins that pull it down further into the soil. The rose stem and leaves form in the light, to emerge the following season. Most types are dormant from summer season to later winter, flowering in the spring and coil, though a few types are fall flowering.
