Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common labels 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 with a cup- or trumpet-shaped corona. The flowers are usually white or yellowish (orange or red in garden kinds), with either uniform or contrasting colored corona and tepals.
Narcissus were popular in historical civilisation, both and botanically medicinally, but formally explained by Linnaeus in his Species Plantarum (1753). The genus is generally considered to have about ten sections with around 50 species. The true range of species has assorted, depending about how they are categorised, as a consequence to similarity between hybridization and types. 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 undiscovered, but it is associated with a Greek word for intoxicated (narcotic) and the misconception of the youngsters of this name who fell in love with his own reflection. The English expression 'daffodil' appears to be produced from "asphodel", with which it was likened commonly.
The kinds are native 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 wild and cultivated plants have naturalised widely, and were unveiled into the Far East to the tenth century prior. Narcissi have a tendency 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 become extinct, while others are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe after the 16th hundred years and by the overdue 19th century were an important commercial crop centred primarily on the Netherlands. Narcissi are popular as slice flowers so that ornamental crops in private and general population gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering a variety 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 ingested accidentally. This property has been exploited for medicinal use within traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in books and fine art, narcissi are associated with a number of themes in several cultures, ranging from death to fortune, and as symbols of spring and coil. The daffodil is the national flower of Wales and the symbol of cancers charities in many countries. The looks of the wild flowers in spring is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering with an underground storage light bulb. They regrow in the following time from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm depending on the species. Dwarf kinds such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might grow as extra tall as 80 cm.
The crops 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. The place stem bears a solitary blossom, but occasionally a cluster of blossoms (umbel). The blossoms, which are conspicuous and white or yellow usually, both or rarely inexperienced sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an external ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The blossoms may hang up down (pendent), or be erect. There are six pollen bearing stamens bordering a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The berry includes a dried capsule that splits (dehisces) releasing numerous black seeds.
The bulb lies dormant after the leaves and blossom stem die again and has contractile roots that yank it down further into the soil. The bloom stem and leaves form in the light bulb, to emerge the following season. Most types are dormant from summer season to overdue winter, flowering in the spring and coil, though a few species are autumn flowering.
