Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common labels including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are being 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 blooms are usually white or yellow (orange or pink in garden types), with either standard or contrasting colored corona and tepals.
Narcissus were well known in historical civilisation, both and botanically medicinally, but formally referred to by Linnaeus in his Varieties Plantarum (1753). The genus is normally considered to have about ten sections with about 50 species. The true quantity of types has mixed, depending about how they are categorized, due to similarity between hybridization and species. 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 real name Narcissus is unknown, but it is linked to a Greek phrase for intoxicated (narcotic) and the misconception of the young ones of this name who fell in love with his own reflection. The English phrase 'daffodil' is apparently produced from "asphodel", with which it was commonly likened.
The species are local to meadows and woods in southern European countries and North Africa with a centre of diversity in the Traditional western Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were unveiled into the Far East to the tenth hundred years prior. Narcissi tend 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, nematodes and mites. 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 increasingly popular in Europe following the 16th hundred years and by the later 19th century were an important commercial crop centred primarily on the Netherlands. Narcissi are popular as slice flowers so when ornamental crops in private and open public gardens today. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering an array of colours and shapes. Like other members of 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 led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in literature and art, narcissi are associated with a number of themes in different cultures, ranging from loss of life to good fortune, and as symbols of springtime. The daffodil is the nationwide rose of Wales and the image of cancers charities in many countries. The looks of the crazy flowers in spring and coil is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to a underground storage light. They regrow in the following 12 months from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm with respect to the species. Dwarf varieties such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may expand as high as 80 cm.
The plants are scapose, having a single central leafless hollow blossom stem (scape). Several green or blue-green, thin, strap-shaped leaves happen from the light. The flower stem usually bears a solitary rose, but sometimes a cluster of bouquets (umbel). The bouquets, which can be usually conspicuous and white or yellow, both or rarely green sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outer ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical designed corona. The blooms may hang down (pendent), or be erect. There are six pollen bearing stamens surrounding a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The super fruit involves a dried out capsule that splits (dehisces) launching numerous black seeds.
The bulb is placed dormant after the leaves and blossom stem die back and has contractile roots that draw it down further into the soil. The blossom leaves and stem form in the light bulb, to emerge the next season. Most varieties are dormant from summer to later winter, flowering in the planting season, though a few kinds are fall flowering.
