Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common names including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are used to describe all or some members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by the cup- or trumpet-shaped corona. The blossoms are generally white or yellow (orange or red in garden varieties), with either standard or contrasting colored corona and tepals.
Narcissus were well known in ancient civilisation, both and botanically medicinally, but formally identified by Linnaeus in his Types Plantarum (1753). The genus is normally thought to have about ten sections with around 50 species. The true volume of kinds has mixed, depending about how they are grouped, scheduled to similarity between kinds and hybridization. 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 undiscovered, but it is often associated with a Greek word for intoxicated (narcotic) and the myth of the youth of that name who fell deeply in love with his own reflection. The English phrase 'daffodil' is apparently derived from "asphodel", with which it was compared commonly.
The varieties are indigenous to meadows and woods in southern European countries and North Africa with a centre of variety in the European Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were introduced in to 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, 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 initial times, but became ever more popular in Europe following the 16th hundred years and by the overdue 19th hundred years were an important commercial crop centred mostly on the Netherlands. Today narcissi are popular as trim blooms as ornamental crops in private and open public gardens. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering a wide range of colours and shapes. 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 use in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in literature and art work, narcissi are associated with a number of themes in several cultures, ranging from fatality to good fortune, and as icons of spring and coil. The daffodil is the nationwide flower of Wales and the sign of cancer charities in many countries. The looks of the untamed flowers in spring is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering with an underground storage bulb. They regrow in the next season from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm depending on species. Dwarf types such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may grow as tall as 80 cm.
The plant life are scapose, having a single central leafless hollow rose stem (scape). Several blue-green or green, thin, strap-shaped leaves happen from the light. The plant stem bears a solitary blossom, but occasionally a cluster of blooms (umbel). The flowers, that are usually conspicuous and white or yellow, both or seldom inexperienced sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outer ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical designed corona. The bouquets may hang down (pendent), or be erect. A couple of six pollen bearing stamens bordering a central style. The ovary is inferior (below the floral parts) consisting of three chambers (trilocular). The fruit includes a dried out capsule that splits (dehisces) launching numerous black seeds.
The bulb lies dormant following the leaves and blossom stem die again and has contractile roots that pull it down further into the soil. The rose stem and leaves form in the light bulb, to emerge the following season. Most types are dormant from summer season to late winter, flowering in the springtime, though a few species are fall flowering.
