Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial vegetation 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 with a cup- or trumpet-shaped corona. The bouquets are usually white or yellow (orange or pink in garden varieties), with either even or contrasting colored corona and tepals.

Narcissus were well known in old civilisation, both medicinally and botanically, but formally detailed by Linnaeus in his Varieties Plantarum (1753). The genus is normally thought to have about ten areas with around 50 species. The true amount of kinds has assorted, depending about how they are classified, credited to similarity between kinds and hybridization. The genus arose some right time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise origin of the true name Narcissus is unidentified, but it is linked to a Greek term for intoxicated (narcotic) and the misconception of the youth of this name who fell deeply in love with his own representation. The English word 'daffodil' is apparently derived from "asphodel", with which it was commonly compared.

The species are indigenous to meadows and woods in southern Europe and North Africa with a centre of variety in the Western Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were introduced in to the Far East prior to the tenth century. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are insect-pollinated also. Known pests, diseases and disorders 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 ever more popular in Europe after the 16th century and by the late 19th century were an important commercial crop centred mostly on the Netherlands. Narcissi are popular as slice bouquets and as ornamental vegetation in private and open public gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering a wide range of shapes and colours. Like other members of the family, narcissi produce a 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 in traditional healing and has led to 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 several cultures, ranging from fatality to good fortune, and as icons of spring. The daffodil is the national bloom of Wales and the icon of tumor charities in many countries. The appearance of the crazy flowers in spring is associated with celebrations in many places.

Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to the underground storage bulb. They regrow in the following yr from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm depending on the species. Dwarf varieties such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might develop as tall as 80 cm.

The crops are scapose, having an individual central leafless hollow flower stem (scape). Several green or blue-green, thin, strap-shaped leaves occur from the bulb. The place stem bears a solitary flower, but sometimes a cluster of flowers (umbel). The plants, which are conspicuous and white or yellowish usually, both or rarely renewable sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outer ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical molded corona. The flowers may suspend down (pendent), or be erect. You can find six pollen bearing stamens encompassing a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The fruit consists of a dried up capsule that splits (dehisces) releasing numerous black seeds.

The bulb is situated dormant after the leaves and bloom stem die again and has contractile roots that pull it down further into the soil. The blossom leaves and stem form in the bulb, to emerge the following season. Most kinds are dormant from summer season to late winter, flowering in the planting season, though a few species are fall flowering.
