Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common labels 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 usually white or yellow (orange or green in garden varieties), with either standard or contrasting colored corona and tepals.
Narcissus were popular in traditional civilisation, both medicinally and botanically, but formally explained by Linnaeus in his Kinds Plantarum (1753). The genus is generally considered to have about ten areas with about 50 species. The true variety of species has varied, depending on how they are categorised, a consequence of to similarity between hybridization and varieties. The genus arose some time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact origins of the name Narcissus is unidentified, but it is often linked to a Greek expression for intoxicated (narcotic) and the misconception of the youngsters of this name who fell in love with his own representation. The English expression 'daffodil' appears to be derived from "asphodel", with which it was compared commonly.
The varieties are native to meadows and woods in southern European countries and North Africa with a centre of variety in the Traditional western Mediterranean, the Iberian peninsula particularly. Both wild and cultivated 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, mites and nematodes. Some Narcissus species have grown to be 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 the Netherlands. Narcissi are popular as cut flowers as ornamental crops in private and public gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering an array of shapes and colours. Like other members with their family, narcissi produce a number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested unintentionally. 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 books and art work, narcissi are associated with a true number of themes in several cultures, ranging from fatality to fortune, and as icons of spring and coil. The daffodil is the countrywide rose of Wales and the mark of cancers charities in many countries. The looks 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 light. They regrow in the following season from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm with respect to the species. Dwarf types such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may grow as tall as 80 cm.
The crops are scapose, having an individual central leafless hollow rose stem (scape). Several blue-green or green, slim, strap-shaped leaves arise from the light bulb. The seed stem bears a solitary bloom, but sometimes a cluster of bouquets (umbel). The blooms, which can be usually conspicuous and white or yellowish, both or hardly ever inexperienced sometimes, 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 shaped corona. The plants may hang down (pendent), or be erect. There are six pollen bearing stamens encircling a central style. The ovary is inferior (below the floral parts) consisting of three chambers (trilocular). The fruits consists of a dried up capsule that splits (dehisces) launching numerous black seeds.
The bulb is dormant after the leaves and bloom stem die back and has contractile origins that yank it down further into the soil. The flower leaves and stem form in the light bulb, to emerge the following season. Most types are dormant from summer months to late winter, flowering in the spring, though a few species are fall flowering.
