Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common brands 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 flowers are usually white or yellowish (orange or green in garden kinds), with either uniform or contrasting coloured tepals and corona.
Narcissus were popular in historical civilisation, both and botanically medicinally, but formally described by Linnaeus in his Types Plantarum (1753). The genus is generally considered to have about ten portions with approximately 50 species. The true number of varieties has varied, depending about how they are classified, due to similarity between types 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 source of the true name Narcissus is unfamiliar, but it is often associated with a Greek term for intoxicated (narcotic) and the misconception of the junior of that name who fell deeply in love with his own reflection. The English word 'daffodil' is apparently derived from "asphodel", with which it was commonly compared.
The species are local to meadows and woods in southern European countries and North Africa with a middle of variety in the American Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were introduced into the Far East before the tenth century. 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 grown to be extinct, while some are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the initial times, but became ever more popular in Europe following the 16th century and by the late 19th century were an important commercial crop centred mainly on the Netherlands. Narcissi are popular as trim bouquets so that 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 a wide range of colours and shapes. Like other members with their family, narcissi create a 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 within traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in artwork and books, narcissi are associated with a true number of themes in several cultures, ranging from death to good fortune, and as icons of springtime. The daffodil is the countrywide rose of Wales and the symbol of tumor charities in many countries. The looks of the untamed flowers in planting season is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering to an underground storage light bulb. They regrow in the next calendar year from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm depending on the species. Dwarf kinds such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might increase as extra tall as 80 cm.
The plant life are scapose, having a single central leafless hollow rose stem (scape). Several blue-green or green, slim, strap-shaped leaves come up from the light. The plant stem usually bears a solitary rose, but once in a while a cluster of bouquets (umbel). The blossoms, which can be usually conspicuous and white or yellow, sometimes both or seldom inexperienced, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an external ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical shaped corona. The blooms may suspend down (pendent), or be erect. A couple of six pollen bearing stamens encircling a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The fruits consists of a dry out capsule that splits (dehisces) releasing numerous black seeds.
The bulb lies dormant after the leaves and blossom stem die back again and has contractile root base that pull it down further in to the soil. The rose leaves and stem form in the bulb, to emerge the following season. Most types are dormant from summertime to later winter, flowering in the springtime, though a few types are autumn flowering.
