Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common titles 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 way of a cup- or trumpet-shaped corona. The plants are usually white or yellow (orange or pink in garden varieties), with either standard or contrasting colored tepals and corona.

Narcissus were popular in old civilisation, both medicinally and botanically, but formally identified by Linnaeus in his Kinds Plantarum (1753). The genus is generally considered to have about ten parts with roughly 50 species. The amount of species has assorted, depending on how they are grouped, a consequence of to similarity between hybridization and varieties. 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 origins of the name Narcissus is unknown, but it is often associated with a Greek word for intoxicated (narcotic) and the myth of the children of that 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 types are native to meadows and woods in southern Europe and North Africa with a centre of diversity in the European 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 become extinct, while others are threatened by increasing urbanisation and tourism.

Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe following the 16th century and by the past due 19th century were an important commercial crop centred mainly on holland. Today narcissi are popular as slice plants so that ornamental plants in private and general public gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a wide range of shapes and colours. Like other members with their family, narcissi produce a true number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested inadvertently. 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 books and fine art, 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 national blossom of Wales and the sign of cancer tumor charities in many countries. The looks of the outdoors flowers in spring is associated with celebrations in many places.

Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to the underground storage light bulb. 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 types such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might expand as extra tall as 80 cm.

The plants are scapose, having an individual central leafless hollow blossom stem (scape). Several blue-green or green, thin, strap-shaped leaves arise from the light. The seed stem bears a solitary flower, but once in a while a cluster of bouquets (umbel). The blooms, which are conspicuous and white or yellowish usually, sometimes both or hardly ever renewable, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an exterior ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical shaped corona. The bouquets may hang up down (pendent), or be erect. There are six pollen bearing stamens surrounding a central style. The ovary is inferior (below the floral parts) consisting of three chambers (trilocular). The fruit contains a dried out capsule that splits (dehisces) launching numerous black seed products.

The bulb lays dormant following the leaves and bloom stem die again and has contractile root base that yank it down further into the soil. The rose leaves and stem form in the light, to emerge the following season. Most kinds are dormant from summer season to late winter, flowering in the spring, though a few types are fall months flowering.
