Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common brands 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 the cup- or trumpet-shaped corona. The bouquets are usually white or yellow (orange or pink in garden varieties), with either even or contrasting colored corona and tepals.
Narcissus were popular in old civilisation, both medicinally and botanically, but formally explained by Linnaeus in his Species Plantarum (1753). The genus is normally thought to have about ten areas with approximately 50 species. The number of species has varied, depending on how they are grouped, anticipated to similarity between species and hybridization. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The exact source of the name Narcissus is unfamiliar, but it is often associated with a Greek expression for intoxicated (narcotic) and the myth of the children of this name who fell in love with his own reflection. The English phrase 'daffodil' is apparently produced from "asphodel", with which it was compared commonly.
The varieties are local to meadows and woods in southern Europe and North Africa with a centre of diversity in the Western Mediterranean, particularly the Iberian peninsula. 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 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 tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe after the 16th century and by the past due 19th hundred years were an important commercial crop centred mainly on holland. Narcissi are popular as lower flowers so when ornamental plants in private and general population gardens today. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering an array of colours and shapes. Like other members of the family, narcissi create a 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 resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in fine art and books, narcissi are associated with a number of themes in several cultures, ranging from death to good fortune, and as symbols of spring. The daffodil is the national blossom of Wales and the icon of tumors charities in many countries. The looks of the crazy flowers in spring is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to an underground storage light. They regrow in the following year from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm depending on species. Dwarf varieties such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might expand as extra tall as 80 cm.
The vegetation are scapose, having a single central leafless hollow rose stem (scape). Several green or blue-green, narrow, strap-shaped leaves arise from the bulb. The plant stem bears a solitary rose, but sometimes a cluster of blossoms (umbel). The plants, that happen to be usually conspicuous and white or yellowish, both or hardly ever renewable sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an external ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical molded corona. The plants may hang down (pendent), or be erect. You will discover six pollen bearing stamens adjoining a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The fruits includes a dried out capsule that splits (dehisces) releasing numerous black seeds.
The bulb is dormant after the leaves and rose stem die again and has contractile root base that draw it down further into the soil. The flower leaves and stem form in the light bulb, to emerge the following season. Most species are dormant from summertime to past due winter, flowering in the spring and coil, though a few species are autumn flowering.
