Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common brands including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are 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 usually white or yellowish (orange or pink in garden types), with either even or contrasting colored tepals and corona.
Narcissus were well known in traditional civilisation, both medicinally and botanically, but formally explained by Linnaeus in his Varieties Plantarum (1753). The genus is normally thought to have about ten parts with about 50 species. The amount of kinds has mixed, depending about how they are labeled, as a consequence to similarity between hybridization and varieties. The genus arose a while 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 often associated with a Greek word for intoxicated (narcotic) and the myth of the youngsters of that name who fell in love with his own reflection. The English word 'daffodil' appears to be derived from "asphodel", with which it was commonly likened.
The species are native to meadows and woods in southern European countries 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 into the Far East before the tenth century. Narcissi tend 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, nematodes and mites. 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 after the 16th century and by the late 19th hundred years were an important commercial crop centred generally on the Netherlands. Narcissi are popular as trim blossoms as ornamental plant life in private and general public gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering a variety of shapes and colours. Like other members with 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 resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in fine art and books, narcissi are associated with a number of themes in several cultures, ranging from loss of life to good fortune, and as icons of springtime. The daffodil is the countrywide flower of Wales and the sign of cancer charities in many countries. The appearance of the untamed flowers in spring and coil is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering with an underground storage bulb. They regrow in the next calendar year from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm depending on the species. Dwarf varieties such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may develop as extra tall as 80 cm.
The vegetation are scapose, having an individual central leafless hollow bloom stem (scape). Several green or blue-green, slim, strap-shaped leaves arise from the light bulb. The herb stem usually bears a solitary bloom, but once in a while a cluster of flowers (umbel). The plants, which are usually conspicuous and white or yellowish, sometimes both or rarely renewable, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an external ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The blossoms may hang up down (pendent), or be erect. There are six pollen bearing stamens encircling a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The fruits involves a dried capsule that splits (dehisces) liberating numerous black seeds.
The bulb lies dormant following the leaves and rose stem die back and has contractile origins that take it down further in to the soil. The bloom leaves and stem form in the light bulb, to emerge the following season. Most varieties are dormant from summertime to past due winter, flowering in the spring and coil, though a few species are fall flowering.
