Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common names 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 way of a cup- or trumpet-shaped corona. The bouquets are generally white or yellow (orange or pink in garden kinds), with either even or contrasting colored tepals and corona.

Narcissus were popular in ancient civilisation, both medicinally and botanically, but formally referred to by Linnaeus in his Kinds Plantarum (1753). The genus is normally considered to have about ten portions with about 50 species. The true range of species has assorted, depending on how they are classified, 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 regions of southwest Europe. The precise origins of the name Narcissus is unidentified, but it is associated with a Greek term for intoxicated (narcotic) and the myth of the youth of this name who fell in love with his own reflection. The English expression 'daffodil' appears to be derived from "asphodel", with which it was likened commonly.

The types are indigenous to meadows and woods in southern European countries and North Africa with a center of diversity in the Traditional western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were released in to the Far East to the tenth hundred years prior. Narcissi tend 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, nematodes and mites. Some Narcissus species have grown to be extinct, while others are threatened by increasing tourism and urbanisation.

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 late 19th hundred years were an important commercial crop centred generally on the Netherlands. Today narcissi are popular as trim blooms so that ornamental vegetation in private and open public gardens. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering an array of colours and shapes. 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 ingested unintentionally. This property has been exploited for medicinal use within traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in artwork and books, narcissi are associated with a number of themes in various cultures, ranging from death to good fortune, and as symbols of planting season. The daffodil is the national rose of Wales and the symbol of cancer charities in many countries. The appearance of the outdoors flowers in spring is associated with celebrations in many places.

Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering to a underground storage light. They regrow in the following yr from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm with regards to the species. Dwarf species such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might increase as extra tall as 80 cm.

The plants are scapose, having a single central leafless hollow blossom stem (scape). Several green or blue-green, small, strap-shaped leaves happen from the light. The plant stem usually bears a solitary blossom, but occasionally a cluster of flowers (umbel). The plants, that are usually conspicuous and white or yellowish, both or almost never green sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an external ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical designed corona. The bouquets may hang up 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 fruit contains a dry capsule that splits (dehisces) launching numerous black seeds.

The bulb is placed dormant following the leaves and rose stem die back again and has contractile root base that move it down further into the soil. The rose stem and leaves form in the bulb, to emerge the following season. Most kinds are dormant from warmer summer months to later winter, flowering in the springtime, though a few species are fall flowering.
