Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common titles 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 with a cup- or trumpet-shaped corona. The bouquets are usually white or yellowish (orange or red in garden varieties), with either uniform or contrasting colored tepals and corona.

Narcissus were popular in ancient civilisation, both medicinally and botanically, but formally explained by Linnaeus in his Species Plantarum (1753). The genus is generally thought to have about ten sections with roughly 50 species. The true quantity of varieties has mixed, depending about how they are labeled, scheduled 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 areas of southwest Europe. The precise source of the name Narcissus is undiscovered, but it is often linked to a Greek expression for intoxicated (narcotic) and the misconception of the junior of that name who fell deeply in love with his own reflection. The English word 'daffodil' is apparently produced from "asphodel", with which it was commonly likened.

The types are indigenous to meadows and woods in southern Europe and North Africa with a center of variety in the American Mediterranean, the Iberian peninsula particularly. Both cultivated and wild 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, disorders and diseases include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have grown to be extinct, while others are threatened by increasing urbanisation and tourism.

Historical accounts suggest narcissi have been cultivated from the initial times, but became ever more popular in Europe following the 16th hundred years and by the overdue 19th century were an important commercial crop centred primarily on the Netherlands. Today narcissi are popular as slash plants so that as ornamental crops in private and public gardens. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering a wide range of colours and shapes. Like other members of their 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 use in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in skill and books, narcissi are associated with a number of themes in several cultures, ranging from fatality to good fortune, and as icons of planting season. The daffodil is the national bloom of Wales and the icon of malignancy charities in many countries. The looks of the crazy flowers in springtime 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 bulb. They regrow in the next calendar year from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm depending on species. Dwarf types such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may increase as large as 80 cm.

The plant life are scapose, having an individual central leafless hollow blossom stem (scape). Several green or blue-green, slim, strap-shaped leaves occur from the light bulb. The flower stem usually bears a solitary flower, but occasionally a cluster of flowers (umbel). The bouquets, that happen to be usually conspicuous and white or yellowish, both or rarely inexperienced sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an exterior ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The plants may suspend down (pendent), or be erect. You will find six pollen bearing stamens bordering a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The fruit involves a dry out capsule that splits (dehisces) releasing numerous black seed products.

The bulb lies dormant after the leaves and flower stem die back again and has contractile root base that pull it down further into the soil. The blossom stem and leaves form in the light, to emerge the following season. Most types are dormant from warmer summer months to later winter, flowering in the planting season, though a few kinds are fall flowering.
