Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common titles 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 by the cup- or trumpet-shaped corona. The plants are generally white or yellow (orange or pink in garden varieties), with either even or contrasting colored corona and tepals.

Narcissus were popular in old civilisation, both and botanically medicinally, but formally identified by Linnaeus in his Varieties Plantarum (1753). The genus is generally considered to have about ten parts with around 50 species. The true quantity of varieties has mixed, depending how they are categorised, due to similarity between species and hybridization. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise source of the name Narcissus is unidentified, but it is associated with a Greek expression for intoxicated (narcotic) and the myth of the junior of that name who fell in love with his own reflection. The English word 'daffodil' appears to be produced from "asphodel", with which it was commonly compared.

The varieties are native to meadows and woods in southern European countries and North Africa with a center of variety in the American Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were unveiled in to the Far East to the tenth century prior. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are also insect-pollinated. Known pests, diseases and disorders include viruses, fungi, the larvae of flies, nematodes and mites. Some Narcissus species have grown to be extinct, while others are threatened by increasing urbanisation and tourism.

Historical accounts suggest narcissi have been cultivated from the initial times, but became ever more popular in Europe following the 16th hundred years and by the later 19th hundred years were an important commercial crop centred generally on holland. Narcissi are popular as lower flowers so that ornamental vegetation in private and general public gardens today. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a variety of colours and shapes. Like other members of these 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 led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in literature and skill, narcissi are associated with a number of themes in various cultures, ranging from death to fortune, and as symbols of spring. The daffodil is the countrywide flower of Wales and the sign of cancers charities in many countries. The looks 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 again after flowering with an underground storage light bulb. They regrow in the next calendar year from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm depending on the species. Dwarf varieties such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may develop as tall as 80 cm.

The plants are scapose, having an individual central leafless hollow flower stem (scape). Several green or blue-green, narrow, strap-shaped leaves come up from the light bulb. The plant stem bears a solitary blossom, but once in a while a cluster of blossoms (umbel). The flowers, which are usually conspicuous and white or yellowish, sometimes both or almost never inexperienced, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an external ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical designed corona. The flowers may hang down (pendent), or be erect. A couple of six pollen bearing stamens encompassing a central style. The ovary is inferior (below the floral parts) consisting of three chambers (trilocular). The berries includes a dry out capsule that splits (dehisces) launching numerous black seeds.

The bulb lays dormant following the leaves and bloom stem die again and has contractile roots that yank it down further into the soil. The flower stem and leaves form in the light, to emerge the next season. Most kinds are dormant from summer season to late winter, flowering in the planting season, though a few varieties are autumn flowering.
