Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common brands including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are used to describe all or some known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted with a cup- or trumpet-shaped corona. The bouquets are usually white or yellowish (orange or pink in garden types), with either even or contrasting colored corona and tepals.

Narcissus were well known in historic civilisation, both and botanically medicinally, but formally identified by Linnaeus in his Kinds Plantarum (1753). The genus is generally considered to have about ten sections with roughly 50 species. The true volume of types has mixed, depending about how they are grouped, credited to similarity between kinds and hybridization. The genus arose some right time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise source of the real name Narcissus is unidentified, but it is associated with a Greek expression for intoxicated (narcotic) and the misconception of the youngsters of that name who fell in love with his own reflection. The English term 'daffodil' appears to be produced from "asphodel", with which it was commonly compared.

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

Historical accounts suggest narcissi have been cultivated from the initial times, but became ever more popular in Europe following the 16th century and by the overdue 19th century were an important commercial crop centred mainly on the Netherlands. Today narcissi are popular as lower bouquets so when ornamental plant life in private and open public gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering a variety of colours and shapes. Like other members of these family, narcissi produce 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 use in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in literature and artwork, narcissi are associated with a number of themes in several cultures, ranging from fatality to good fortune, and as symbols of planting season. The daffodil is the national blossom of Wales and the symbol of tumors 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 again after flowering to a underground storage light. They regrow in the next year from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm with respect to the species. Dwarf types such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might develop as large as 80 cm.

The vegetation are scapose, having a single central leafless hollow bloom stem (scape). Several blue-green or green, narrow, strap-shaped leaves arise from the light bulb. The herb stem usually bears a solitary blossom, but occasionally a cluster of plants (umbel). The blooms, that happen to be conspicuous and white or yellowish usually, both or seldom renewable sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an exterior ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical shaped corona. The bouquets may suspend down (pendent), or be erect. A couple of six pollen bearing stamens adjoining a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The berries consists of a dried out capsule that splits (dehisces) releasing numerous black seed products.

The bulb sits dormant after the leaves and blossom stem die back and has contractile root base that pull it down further into the soil. The bloom stem and leaves form in the bulb, to emerge the next season. Most varieties are dormant from summer season to past due winter, flowering in the planting season, though a few kinds are autumn flowering.
