Narcissus /n?:r's?s?s/ is a genus of predominantly 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 plants are usually white or yellow (orange or pink in garden varieties), with either even or contrasting coloured tepals and corona.
Narcissus were popular in historical civilisation, both and botanically medicinally, but formally identified by Linnaeus in his Types Plantarum (1753). The genus is generally thought to have about ten parts with approximately 50 species. The amount of types has mixed, depending on how they are labeled, scheduled to similarity between species and hybridization. The genus arose some right amount of time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise source of the name Narcissus is mysterious, but it is associated with a Greek phrase for intoxicated (narcotic) and the myth of the youngsters of this name who fell in love with his own reflection. The English word 'daffodil' is apparently produced from "asphodel", with which it was commonly likened.
The varieties are indigenous to meadows and woods in southern European countries and North Africa with a centre of diversity in the Western Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were released in to 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, 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 following the 16th hundred years and by the overdue 19th century were an important commercial crop centred generally on the Netherlands. Narcissi are popular as slash 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 categorized into divisions, covering an array of colours and shapes. Like other members of 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 used in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in books and art, narcissi are associated with a number of themes in several cultures, ranging from fatality to fortune, and as symbols of spring and coil. The daffodil is the countrywide bloom of Wales and the image of cancer tumor charities in many countries. The appearance of the outrageous flowers in springtime 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 bulb. They regrow in the next yr from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm with respect to the species. Dwarf varieties such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may increase as large 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 come up from the light bulb. The place stem bears a solitary rose, but occasionally a cluster of blossoms (umbel). The bouquets, which can be conspicuous and white or yellowish usually, sometimes both or seldom green, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outside ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical shaped corona. The plants may hang up down (pendent), or be erect. You will find six pollen bearing stamens bordering a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The super fruit contains a dried out capsule that splits (dehisces) releasing numerous black seeds.
The bulb lies dormant after the leaves and blossom stem die again and has contractile root base that yank it down further into the soil. The rose leaves and stem form in the light bulb, to emerge the next season. Most types are dormant from warmer summer months to overdue winter, flowering in the spring and coil, though a few kinds are fall months flowering.
