Narcissus /n?:r's?s?s/ is a genus of predominantly 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 known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted with a cup- or trumpet-shaped corona. The plants are generally white or yellowish (orange or red in garden varieties), with either standard or contrasting colored tepals and corona.

Narcissus were popular in historic civilisation, both and botanically medicinally, but formally identified by Linnaeus in his Kinds Plantarum (1753). The genus is normally considered to have about ten portions with around 50 species. The amount of kinds has mixed, depending about how they are categorised, scheduled to similarity between kinds 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 exact source of the real name Narcissus is unknown, but it is linked to 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 derived from "asphodel", with which it was commonly compared.

The types are native to meadows and woods in southern European countries and North Africa with a center of diversity in the European 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 tend to be long-lived bulbs, which propagate by division, but are also insect-pollinated. Known pests, diseases and disorders include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have grown to be extinct, while some are threatened by increasing tourism and urbanisation.

Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe following the 16th hundred years and by the overdue 19th century were an important commercial crop centred mainly on holland. Today narcissi are popular as slice blossoms and since ornamental crops in private and general population gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a variety of colours and shapes. 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 accidentally ingested. This property has been exploited for medicinal utilization in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in art work and literature, narcissi are associated with a number of themes in several cultures, ranging from death to fortune, and as icons of spring and coil. The daffodil is the countrywide flower of Wales and the sign of malignancy charities in many countries. The looks of the untamed flowers in springtime is associated with celebrations in many places.

Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering to an underground storage light bulb. They regrow in the next time from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm with respect to the species. Dwarf varieties such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might expand as high 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 occur from the bulb. The seed stem bears a solitary rose, but sometimes a cluster of blossoms (umbel). The bouquets, which are usually conspicuous and white or yellow, sometimes both or seldom renewable, contain 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 shaped corona. The blossoms may hang down (pendent), or be erect. A couple of six pollen bearing stamens encompassing a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The berries involves a dried up capsule that splits (dehisces) liberating numerous black seed products.

The bulb is dormant following the leaves and blossom stem die back again and has contractile root base that yank it down further in to the soil. The rose leaves and stem form in the light, to emerge the following season. Most varieties are dormant from summer months to overdue winter, flowering in the planting season, though a few kinds are fall months flowering.
