Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common names 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 way of a cup- or trumpet-shaped corona. The blossoms are usually white or yellowish (orange or pink in garden varieties), with either uniform or contrasting colored corona and tepals.
Narcissus were popular in traditional civilisation, both and botanically medicinally, but formally identified by Linnaeus in his Varieties Plantarum (1753). The genus is normally thought to have about ten sections with around 50 species. The number of types has varied, depending about how they are labeled, thanks 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 areas of southwest Europe. The precise source of the true name Narcissus is unfamiliar, but it is linked to a Greek word for intoxicated (narcotic) and the misconception of the children of that name who fell in love with his own reflection. The English expression 'daffodil' is apparently derived from "asphodel", with which it was compared commonly.
The varieties are indigenous to meadows and woods in southern Europe and North Africa with a center of diversity in the Traditional western Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were launched in to the Far East to the tenth century prior. Narcissi tend to be long-lived bulbs, which propagate by division, but are also insect-pollinated. Known pests, disorders and diseases include viruses, fungi, the larvae of flies, nematodes and mites. Some Narcissus species have become extinct, while some are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became ever more popular in Europe after the 16th hundred years and by the overdue 19th century were an important commercial crop centred mainly on the Netherlands. Today narcissi are popular as slash plants as ornamental plants in private and public gardens. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are categorized 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 used in traditional healing and has led to 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 fatality to good fortune, and as symbols of springtime. The daffodil is the national flower of Wales and the icon of cancer tumor charities in many countries. The looks of the untamed 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 the underground storage light bulb. They regrow in the next time from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm with respect to the species. Dwarf kinds such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might grow as tall as 80 cm.
The vegetation are scapose, having a single central leafless hollow rose stem (scape). Several green or blue-green, thin, strap-shaped leaves occur from the light. The herb stem usually bears a solitary rose, but once in a while a cluster of plants (umbel). The plants, that happen to be conspicuous and white or yellow usually, sometimes both or rarely renewable, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outer ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical formed corona. The blooms may suspend down (pendent), or be erect. A couple of six pollen bearing stamens adjoining a central style. The ovary is substandard (below the floral parts) consisting of three chambers (trilocular). The fruits involves a dried capsule that splits (dehisces) releasing numerous black seed products.
The bulb is situated dormant after the leaves and flower stem die again and has contractile root base that move it down further in to the soil. The blossom stem and leaves form in the bulb, to emerge the next season. Most species are dormant from summer months to past due winter, flowering in the planting season, though a few kinds are autumn flowering.
