Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common names including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are being used to describe all or some members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by a cup- or trumpet-shaped corona. The bouquets are generally white or yellowish (orange or pink in garden varieties), with either standard or contrasting coloured tepals and corona.
Narcissus were popular in historical civilisation, both medicinally and botanically, but formally defined by Linnaeus in his Kinds Plantarum (1753). The genus is generally considered to have about ten sections with around 50 species. The true range of varieties has mixed, depending on how they are classified, credited to similarity between varieties and hybridization. The genus arose some right amount of time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise origins of the true name Narcissus is undiscovered, but it is often associated with a Greek word for intoxicated (narcotic) and the myth of the children of this name who fell in love with his own reflection. The English phrase 'daffodil' is apparently produced from "asphodel", with which it was likened commonly.
The species are local to meadows and woods in southern European countries and North Africa with a middle of variety in the Western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were launched into the Far East to the tenth century prior. Narcissi have a tendency 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 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 century and by the later 19th hundred years were an important commercial crop centred generally on holland. Narcissi are popular as chop blooms so that ornamental vegetation in private and general population 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 a wide range of shapes and colours. 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 used in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in literature and skill, narcissi are associated with a true number of themes in different cultures, ranging from fatality to fortune, and as icons of spring. The daffodil is the national rose of Wales and the image of cancer charities in many countries. The looks of the wild 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 to an underground storage light. They regrow in the next time from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm with respect to the species. Dwarf varieties such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may develop as large as 80 cm.
The plants are scapose, having a single central leafless hollow flower stem (scape). Several blue-green or green, thin, strap-shaped leaves arise from the light bulb. The herb stem usually bears a solitary flower, but occasionally a cluster of bouquets (umbel). The bouquets, that are conspicuous and white or yellow usually, both or hardly ever inexperienced sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an external ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical designed corona. The flowers may hang up down (pendent), or be erect. There are six pollen bearing stamens surrounding a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The fruits includes a dried out capsule that splits (dehisces) liberating numerous black seed products.
The bulb sits dormant following the leaves and blossom stem die again and has contractile origins that move it down further in to the soil. The blossom stem and leaves form in the light bulb, to emerge the following season. Most varieties are dormant from summertime to late winter, flowering in the spring, though a few types are autumn flowering.
