Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common labels 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 blooms are generally white or yellow (orange or green in garden types), with either uniform or contrasting coloured tepals and corona.

Narcissus were well known in early civilisation, both medicinally and botanically, but formally referred to by Linnaeus in his Varieties Plantarum (1753). The genus is generally thought to have about ten areas with about 50 species. The amount of kinds has assorted, depending on how they are labeled, scheduled 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 exact origin of the name Narcissus is unknown, but it is associated with a Greek term for intoxicated (narcotic) and the misconception of the children of this name who fell deeply in love with his own reflection. The English term 'daffodil' is apparently produced from "asphodel", with which it was commonly compared.

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

Historical accounts suggest narcissi have been cultivated from the earliest times, but became ever more popular in Europe after the 16th hundred years and by the past due 19th hundred years were an important commercial crop centred mainly on the Netherlands. Today narcissi are popular as trim plants so that as ornamental plant life in private and public gardens. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering an array 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 ingested accidentally. 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 and books, narcissi are associated with a true number of themes in different cultures, ranging from fatality to fortune, and as icons of springtime. The daffodil is the countrywide bloom of Wales and the symbol of malignancy charities in many countries. The appearance of the crazy flowers in springtime is associated with festivals in many places.

Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to an underground storage bulb. They regrow in the following year from brown-skinned ovoid light 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 level of 5-8 cm, while Narcissus tazetta might increase as tall as 80 cm.

The plants are scapose, having a single central leafless hollow bloom stem (scape). Several green or blue-green, narrow, strap-shaped leaves arise from the light. The flower stem usually bears a solitary flower, but once in a while a cluster of blooms (umbel). The bouquets, that are conspicuous and white or yellow usually, sometimes both or rarely green, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outside ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical molded corona. The blooms may hang down (pendent), or be erect. A couple of six pollen bearing stamens bordering a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The fruits includes a dried up capsule that splits (dehisces) launching numerous black seeds.

The bulb sits dormant after the leaves and rose stem die again and has contractile roots that yank it down further into the soil. The blossom leaves and stem form in the light, to emerge the following season. Most species are dormant from warmer summer months to late winter, flowering in the spring and coil, though a few varieties are fall months flowering.
