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 being 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 blossoms are usually white or yellowish (orange or green in garden varieties), with either even or contrasting coloured corona and tepals.
Narcissus were popular in historical civilisation, both medicinally and botanically, but formally detailed 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 about how they are categorized, due to similarity between species and hybridization. The genus arose time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise origin of the real name Narcissus is mysterious, but it is linked to a Greek word for intoxicated (narcotic) and the myth of the youth of this name who fell in love with his own reflection. The English term 'daffodil' is apparently derived from "asphodel", with which it was commonly compared.
The types are native to meadows and woods in southern Europe and North Africa with a center of variety in the Western Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were introduced in to the ASIA 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 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 increasingly popular in Europe after the 16th century and by the late 19th hundred years were an important commercial crop centred primarily on the Netherlands. Narcissi are popular as lower plants and as ornamental plant life in private and open public gardens today. The long history of breeding has resulted in 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 with their family, narcissi produce 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 in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in art work and books, narcissi are associated with a number of themes in various cultures, ranging from loss of life to fortune, and as icons of spring. The daffodil is the nationwide bloom of Wales and the image of malignancy charities in many countries. The looks of the outrageous flowers in springtime is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering for an underground storage light bulb. They regrow in the following season from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm with regards to the species. Dwarf types such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may develop as extra tall as 80 cm.
The plant life are scapose, having a single central leafless hollow flower stem (scape). Several blue-green or green, slim, strap-shaped leaves occur from the bulb. The herb stem bears a solitary blossom, but once in a while a cluster of flowers (umbel). The flowers, that are usually conspicuous and white or yellowish, both or almost never renewable sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an external ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical designed corona. The blossoms may hang up down (pendent), or be erect. There are six pollen bearing stamens encircling a central style. The ovary is second-rate (below the floral parts) consisting of three chambers (trilocular). The berries consists of a dried capsule that splits (dehisces) liberating numerous black seed products.
The bulb is dormant following the leaves and rose stem die back again and has contractile root base that move it down further in to the soil. The rose leaves and stem form in the light, to emerge the following season. Most kinds are dormant from summertime to late winter, flowering in the spring, though a few varieties are autumn flowering.
