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 being used to describe all or some members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by way of a cup- or trumpet-shaped corona. The blossoms are usually white or yellowish (orange or green in garden types), with either uniform or contrasting coloured corona and tepals.

Narcissus were popular in old civilisation, both and botanically medicinally, but formally referred to by Linnaeus in his Types Plantarum (1753). The genus is normally considered to have about ten areas with approximately 50 species. The true amount of kinds has varied, depending about how they are classified, as a consequence to similarity between hybridization and species. The genus arose some right amount of time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact source of the name Narcissus is unknown, but it is often linked to a Greek term for intoxicated (narcotic) and the myth of the youth of this name who fell deeply in love with his own representation. The English word 'daffodil' is apparently produced from "asphodel", with which it was compared commonly.

The types are native to meadows and woods in southern Europe and North Africa with a middle of diversity in the Western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were introduced in to the Far East prior to the tenth century. 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, mites and nematodes. Some Narcissus species have become 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 mostly on holland. Today narcissi are popular as lower blossoms so that as ornamental vegetation in private and public gardens. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering a variety of shapes and colours. Like other members of the family, narcissi produce 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 in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in books and artwork, narcissi are associated with a number of themes in several cultures, ranging from fatality to fortune, and as symbols of spring and coil. The daffodil is the countrywide blossom of Wales and the symbol of cancer tumor charities in many countries. The appearance of the untamed flowers in spring and coil is associated with festivals in many places.

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

The crops are scapose, having a single central leafless hollow flower stem (scape). Several green or blue-green, slim, strap-shaped leaves occur from the light bulb. The vegetable stem usually bears a solitary bloom, but occasionally a cluster of plants (umbel). The bouquets, which are usually conspicuous and white or yellowish, both or rarely green sometimes, consist of 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 disc to conical shaped corona. The plants may hang down (pendent), or be erect. There are six pollen bearing stamens surrounding a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The super fruit includes a dry capsule that splits (dehisces) launching numerous black seeds.

The bulb lies dormant after the leaves and rose stem die back again and has contractile root base that pull it down further in to the soil. The flower leaves and stem form in the bulb, to emerge the following season. Most varieties are dormant from summer season to overdue winter, flowering in the spring, though a few kinds are fall flowering.
