Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plant life 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 bouquets are usually white or yellowish (orange or green in garden varieties), with either even or contrasting colored tepals and corona.
Narcissus were popular in old civilisation, both medicinally and botanically, but formally explained by Linnaeus in his Types Plantarum (1753). The genus is generally thought to have about ten areas with about 50 species. The amount of types has varied, depending about how they are labeled, anticipated to similarity between species and hybridization. The genus arose some time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact origins of the real name Narcissus is anonymous, but it is often associated with a Greek expression for intoxicated (narcotic) and the myth of the youth of that name who fell deeply in love with his own reflection. The English term 'daffodil' appears to be derived from "asphodel", with which it was compared commonly.
The species are local to meadows and woods in southern European countries and North Africa with a centre of diversity in the American 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 grown to be 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 after the 16th century and by the overdue 19th century were an important commercial crop centred primarily on the Netherlands. Narcissi are popular as cut blooms so that as ornamental plants in private and public gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a wide range of shapes and colours. 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 use in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in art work and books, narcissi are associated with a true number of themes in various cultures, ranging from loss of life to fortune, and as symbols of spring. The daffodil is the national rose of Wales and the sign of cancers 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 again after flowering to the underground storage bulb. They regrow in the next season from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf species such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may expand as large as 80 cm.
The vegetation are scapose, having an individual central leafless hollow rose stem (scape). Several blue-green or green, thin, strap-shaped leaves occur from the bulb. The flower stem bears a solitary blossom, but once in a while a cluster of plants (umbel). The blooms, that are usually conspicuous and white or yellowish, both or seldom renewable sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an exterior ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The flowers may hang up down (pendent), or be erect. There are six pollen bearing stamens surrounding a central style. The ovary is substandard (below the floral parts) consisting of three chambers (trilocular). The berry includes a dried up capsule that splits (dehisces) launching numerous black seeds.
The bulb is situated dormant after the leaves and rose stem die back and has contractile roots that draw it down further into the soil. The bloom leaves and stem form in the bulb, to emerge the following season. Most species are dormant from summer season to past due winter, flowering in the planting season, though a few kinds are fall flowering.
