Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plants 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 known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by a cup- or trumpet-shaped corona. The plants are usually white or yellowish (orange or pink in garden kinds), with either uniform or contrasting colored corona and tepals.

Narcissus were popular in ancient civilisation, both medicinally and botanically, but formally identified by Linnaeus in his Species Plantarum (1753). The genus is normally considered to have about ten portions with roughly 50 species. The true volume of species has mixed, depending about how they are labeled, due to similarity between types and hybridization. The genus arose some right amount of 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 unfamiliar, but it is linked to a Greek expression for intoxicated (narcotic) and the myth of the young ones of that name who fell in love with his own reflection. The English expression 'daffodil' is apparently produced from "asphodel", with which it was likened commonly.

The types are native to meadows and woods in southern European countries and North Africa with a center of variety in the American Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were introduced into the Far East prior to the tenth century. Narcissi have a tendency 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 others are threatened by increasing urbanisation and tourism.

Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe following the 16th century and by the later 19th century were an important commercial crop centred mostly on the Netherlands. Narcissi are popular as chop blossoms as ornamental vegetation in private and general population gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering a variety of shapes and colours. Like other members of the 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 use in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in literature and art work, narcissi are associated with a true number of themes in several cultures, ranging from death to fortune, and as symbols of planting season. The daffodil is the countrywide flower of Wales and the symbol of cancers charities in many countries. The looks 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 a underground storage light. They regrow in the next 12 months from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm with respect to the species. Dwarf species such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might increase as tall as 80 cm.

The vegetation are scapose, having a single central leafless hollow rose stem (scape). Several green or blue-green, thin, strap-shaped leaves come up from the bulb. The herb stem bears a solitary flower, but sometimes a cluster of bouquets (umbel). The blooms, that are usually conspicuous and white or yellowish, sometimes both or rarely inexperienced, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an exterior ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical molded corona. The blossoms may hang up down (pendent), or be erect. There are six pollen bearing stamens encircling a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The berry involves a dried capsule that splits (dehisces) liberating numerous black seed products.

The bulb is placed dormant following the leaves and rose stem die back and has contractile root base that take it down further in to the soil. The rose stem and leaves form in the light bulb, to emerge the next season. Most species are dormant from summer time to late winter, flowering in the spring and coil, though a few kinds are autumn flowering.
