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 way of a cup- or trumpet-shaped corona. The flowers are generally white or yellow (orange or pink in garden varieties), with either standard or contrasting coloured tepals and corona.
Narcissus were well known in early civilisation, both medicinally and botanically, but formally identified by Linnaeus in his Kinds Plantarum (1753). The genus is normally considered to have about ten sections with about 50 species. The amount of kinds has varied, depending how they are classified, due to similarity between species and hybridization. The genus arose some right time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact origin of the name Narcissus is unknown, but it is associated with a Greek phrase for intoxicated (narcotic) and the myth of the youngsters of that name who fell deeply in love with his own reflection. The English term 'daffodil' appears to be produced from "asphodel", with which it was commonly compared.
The varieties are indigenous to meadows and woods in southern European countries and North Africa with a centre of diversity in the European Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were introduced into the Far East before the tenth century. Narcissi tend to be long-lived bulbs, which propagate by division, but are insect-pollinated also. Known pests, disorders and diseases include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have become extinct, while others 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 hundred years were an important commercial crop centred mostly on holland. Today narcissi are popular as cut blooms and since ornamental plants in private and general public gardens. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering an array of colours and shapes. Like other members of these family, narcissi create 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 led to 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 death to fortune, and as icons of planting season. The daffodil is the countrywide rose of Wales and the icon of cancers charities in many countries. The looks of the outrageous flowers in planting season is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering to a underground storage light bulb. They regrow in the next yr from brown-skinned ovoid bulbs with pronounced necks, and reach levels of 5-80 cm depending on the species. Dwarf kinds such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might develop as extra tall as 80 cm.
The plant life are scapose, having a single central leafless hollow rose stem (scape). Several blue-green or green, narrow, strap-shaped leaves arise from the light bulb. The herb stem bears a solitary rose, but occasionally a cluster of blossoms (umbel). The bouquets, which can be usually conspicuous and white or yellowish, sometimes both or rarely inexperienced, contain 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 shaped corona. The plants may hang up down (pendent), or be erect. A couple of six pollen bearing stamens surrounding a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The berry contains a dried out capsule that splits (dehisces) launching numerous black seeds.
The bulb sits dormant following the leaves and bloom stem die back and has contractile origins that pull it down further in to the soil. The flower stem and leaves form in the bulb, to emerge the following season. Most types are dormant from summertime to past due winter, flowering in the planting season, though a few varieties are autumn flowering.
