Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial vegetation 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 the cup- or trumpet-shaped corona. The blooms are generally white or yellow (orange or green in garden kinds), with either uniform or contrasting colored corona and tepals.
Narcissus were well known in historic civilisation, both and botanically medicinally, but formally described by Linnaeus in his Varieties Plantarum (1753). The genus is generally considered to have about ten parts with around 50 species. The number of varieties has varied, depending on how they are labeled, due to similarity between varieties and hybridization. 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 name Narcissus is undiscovered, but it is linked to a Greek expression for intoxicated (narcotic) and the myth of the junior of that name who fell deeply in love with his own reflection. The English expression 'daffodil' appears to be produced from "asphodel", with which it was likened commonly.
The kinds are native to meadows and woods in southern European countries and North Africa with a centre of variety in the European Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were released into 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, diseases and disorders include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have become extinct, while others are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe after the 16th hundred years and by the later 19th hundred years were an important commercial crop centred generally on the Netherlands. Narcissi are popular as lower flowers so that 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 grouped into divisions, covering an array 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 ingested inadvertently. This property has been exploited for medicinal use within traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in fine art and literature, narcissi are associated with a true number of themes in several cultures, ranging from fatality to good fortune, and as icons of spring. The daffodil is the nationwide rose of Wales and the icon of cancer 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 back after flowering to an underground storage light. They regrow in the following year from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm with respect to the species. Dwarf types such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might increase as extra tall as 80 cm.
The vegetation are scapose, having an individual central leafless hollow bloom stem (scape). Several blue-green or green, slim, strap-shaped leaves come up from the light. The herb stem bears a solitary flower, but sometimes a cluster of flowers (umbel). The bouquets, which are usually conspicuous and white or yellowish, both or almost never 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 disc to conical shaped corona. The plants may suspend down (pendent), or be erect. There are six pollen bearing stamens surrounding a central style. The ovary is second-rate (below the floral parts) consisting of three chambers (trilocular). The berry consists of a dried out capsule that splits (dehisces) releasing numerous black seeds.
The bulb is placed dormant after the leaves and bloom stem die back and has contractile origins that move it down further into the soil. The flower stem and leaves form in the light bulb, to emerge the next season. Most varieties are dormant from summer time to overdue winter, flowering in the spring, though a few types are fall flowering.
