Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common names 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 a cup- or trumpet-shaped corona. The blooms are generally white or yellow (orange or pink in garden types), with either even or contrasting coloured tepals and corona.
Narcissus were popular in traditional civilisation, both medicinally and botanically, but formally explained by Linnaeus in his Varieties Plantarum (1753). The genus is generally thought to have about ten parts with approximately 50 species. The true amount of species has mixed, depending about how they are grouped, as a consequence to similarity between hybridization and species. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The exact origins of the true name Narcissus is anonymous, but it is linked to a Greek expression for intoxicated (narcotic) and the misconception of the youth of this name who fell deeply in love with his own representation. The English term 'daffodil' appears to be produced 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 diversity in the Western Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were created in to the ASIA to the tenth hundred years prior. Narcissi have a tendency 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, mites and nematodes. Some Narcissus species have become extinct, while some 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 hundred years and by the later 19th century were an important commercial crop centred mostly on holland. Today narcissi are popular as cut plants and as ornamental plants in private and general population gardens. 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 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 use in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in art work and books, narcissi are associated with a true number of themes in various cultures, ranging from death to fortune, and as icons of planting season. The daffodil is the national rose of Wales and the sign of cancer charities in many countries. The looks of the untamed flowers in spring is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering for an underground storage light. They regrow in the following 12 months from brown-skinned ovoid 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 expand as high as 80 cm.
The crops are scapose, having a single central leafless hollow bloom stem (scape). Several blue-green or green, thin, strap-shaped leaves occur from the light bulb. The plant stem usually bears a solitary rose, but occasionally a cluster of bouquets (umbel). The flowers, which are usually conspicuous and white or yellowish, both or hardly ever renewable sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outer ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical molded corona. The bouquets may hang up down (pendent), or be erect. There are six pollen bearing stamens bordering a central style. The ovary is second-rate (below the floral parts) consisting of three chambers (trilocular). The fruit consists of a dry capsule that splits (dehisces) launching numerous black seed products.
The bulb is dormant after the leaves and bloom stem die back and has contractile origins that move it down further in to the soil. The blossom stem and leaves form in the light, to emerge the next season. Most types are dormant from summer months to past due winter, flowering in the springtime, though a few species are fall flowering.
