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 members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by way of a cup- or trumpet-shaped corona. The plants are generally white or yellow (orange or pink in garden varieties), with either uniform or contrasting colored tepals and corona.

Narcissus were well known in ancient civilisation, both medicinally and botanically, but formally referred to by Linnaeus in his Kinds Plantarum (1753). The genus is generally thought to have about ten sections with approximately 50 species. The amount of varieties has varied, depending how they are classified, thanks to similarity between hybridization and types. The genus arose 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 undiscovered, but it is linked to a Greek expression for intoxicated (narcotic) and the myth of the junior of this name who fell deeply in love with his own reflection. The English expression 'daffodil' is apparently produced from "asphodel", with which it was likened commonly.

The types are local to meadows and woods in southern Europe and North Africa with a center of variety in the Western Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were presented in to the ASIA to the tenth hundred years prior. 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 become extinct, while some 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 after the 16th century and by the overdue 19th century were an important commercial crop centred primarily on the Netherlands. Narcissi are popular as slash plants and as ornamental plant life in private and public gardens today. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering a wide range of shapes and colours. Like other members of these family, narcissi produce a true 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 led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in books and art work, narcissi are associated with a number of themes in various cultures, ranging from death to fortune, and as symbols of spring and coil. The daffodil is the countrywide rose of Wales and the image of cancer charities in many countries. The looks of the outdoors flowers in springtime is associated with celebrations in many places.

Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to a underground storage bulb. They regrow in the following season from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm with respect to the species. Dwarf types such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may increase as high as 80 cm.

The plants are scapose, having a single central leafless hollow rose stem (scape). Several blue-green or green, thin, strap-shaped leaves arise from the bulb. The plant stem bears a solitary blossom, but sometimes a cluster of flowers (umbel). The flowers, that are usually conspicuous and white or yellow, both or hardly ever inexperienced sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outside ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical molded corona. The blooms may hang down (pendent), or be erect. There are six pollen bearing stamens encompassing a central style. The ovary is substandard (below the floral parts) consisting of three chambers (trilocular). The fruit includes a dry out capsule that splits (dehisces) liberating numerous black seed products.

The bulb lays dormant following the leaves and flower stem die back again and has contractile root base that take it down further in to the soil. The bloom leaves and stem form in the light bulb, to emerge the next season. Most kinds are dormant from summer season to past due winter, flowering in the spring and coil, though a few varieties are autumn flowering.
