Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common brands including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are used to describe all or some members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted with a cup- or trumpet-shaped corona. The flowers are generally white or yellowish (orange or red in garden varieties), with either uniform or contrasting coloured tepals and corona.

Narcissus were popular in historic civilisation, both medicinally and botanically, but formally described by Linnaeus in his Types Plantarum (1753). The genus is normally considered to have about ten areas with around 50 species. The true volume of species has varied, depending about how they are labeled, due 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 origin of the name Narcissus is anonymous, but it is often associated with a Greek term for intoxicated (narcotic) and the myth of the youngsters of this name who fell in love with his own reflection. The English term 'daffodil' appears to be derived from "asphodel", with which it was commonly likened.

The species are local to meadows and woods in southern Europe and North Africa with a center of variety in the American Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were introduced into the Far East prior to the tenth century. Narcissi tend 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, mites and nematodes. 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 ever more popular in Europe after the 16th hundred years and by the later 19th hundred years were an important commercial crop centred generally on holland. Today narcissi are popular as slice plants and since ornamental plant life in private and open public gardens. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering an array of colours and shapes. Like other members of these family, narcissi create a true 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 within traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in art work and literature, narcissi are associated with a number of themes in various cultures, ranging from death to good fortune, and as symbols of springtime. The daffodil is the countrywide bloom of Wales and the image of malignancy charities in many countries. The appearance of the untamed flowers in spring is associated with celebrations in many places.

Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering to a underground storage light bulb. They regrow in the next time 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 elevation of 5-8 cm, while Narcissus tazetta may develop as large as 80 cm.

The plants are scapose, having a single central leafless hollow rose stem (scape). Several green or blue-green, thin, strap-shaped leaves happen from the light bulb. The flower stem bears a solitary rose, but sometimes a cluster of blooms (umbel). The flowers, that happen to be conspicuous and white or yellowish usually, both or seldom renewable sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outside ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical shaped corona. The blossoms may hang up down (pendent), or be erect. A couple of six pollen bearing stamens adjoining a central style. The ovary is substandard (below the floral parts) consisting of three chambers (trilocular). The fruits includes a dried out capsule that splits (dehisces) launching numerous black seed products.

The bulb is situated dormant following the leaves and blossom stem die back and has contractile roots that yank it down further in to the soil. The rose leaves and stem form in the light bulb, to emerge the next season. Most kinds are dormant from summer months to late winter, flowering in the spring, though a few types are autumn flowering.
