Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common labels including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are being used to describe all or some members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by a cup- or trumpet-shaped corona. The bouquets are usually white or yellowish (orange or green in garden varieties), with either uniform or contrasting coloured tepals and corona.

Narcissus were popular in old civilisation, both and botanically medicinally, but formally identified by Linnaeus in his Types Plantarum (1753). The genus is generally thought to have about ten parts with around 50 species. The true volume of species has varied, depending about how they are labeled, as a consequence to similarity between hybridization and kinds. The genus arose 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 unidentified, but it is associated with a Greek phrase for intoxicated (narcotic) and the myth of the youth of that name who fell in love with his own reflection. The English word 'daffodil' is apparently produced from "asphodel", with which it was commonly likened.

The species are local to meadows and woods in southern Europe and North Africa with a centre of variety in the Traditional western Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were introduced in to the Far East before the tenth century. 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 become extinct, while some are threatened by increasing tourism and urbanisation.

Historical accounts suggest narcissi have been cultivated from the earliest times, but became ever more popular in Europe following the 16th century and by the late 19th century were an important commercial crop centred generally on the Netherlands. Today narcissi are popular as lower plants so when 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 labeled into divisions, covering an array of colours and shapes. Like other members of these family, narcissi create 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 used in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in fine art and books, narcissi are associated with a true number of themes in several cultures, ranging from fatality to good fortune, and as icons of spring and coil. The daffodil is the countrywide bloom of Wales and the mark of cancer charities in many countries. The appearance of the outrageous flowers in spring 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 bulb. They regrow in the following season from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm depending on species. Dwarf kinds such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may develop as extra tall as 80 cm.

The plants are scapose, having an individual central leafless hollow bloom stem (scape). Several blue-green or green, small, strap-shaped leaves arise from the light bulb. The vegetable stem bears a solitary bloom, but once in a while a cluster of plants (umbel). The blossoms, that happen to be usually conspicuous and white or yellowish, both or rarely renewable sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outside ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical shaped corona. The blooms may hang up down (pendent), or be erect. You can find six pollen bearing stamens encircling a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The super fruit contains a dried capsule that splits (dehisces) liberating numerous black seeds.

The bulb sits dormant following the leaves and flower stem die again and has contractile root base that take it down further in to the soil. The flower leaves and stem form in the light bulb, to emerge the next season. Most varieties are dormant from warmer summer months to overdue winter, flowering in the spring, though a few varieties are fall months flowering.
