Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common brands including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are being used to describe all or some known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by way of a cup- or trumpet-shaped corona. The bouquets are generally white or yellowish (orange or pink in garden types), with either standard or contrasting colored corona and tepals.
Narcissus were popular in early civilisation, both medicinally and botanically, but formally described by Linnaeus in his Species Plantarum (1753). The genus is generally considered to have about ten sections with approximately 50 species. The number of varieties has assorted, depending how they are labeled, as a consequence to similarity between hybridization and varieties. The genus arose time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise origin of the real name Narcissus is anonymous, but it is often linked to a Greek term for intoxicated (narcotic) and the misconception of the children of that name who fell in love with his own representation. The English phrase 'daffodil' is apparently derived from "asphodel", with which it was commonly likened.
The species are indigenous to meadows and woods in southern Europe and North Africa with a centre of variety in the European Mediterranean, particularly the Iberian peninsula. Both cultivated and wild 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, mites and nematodes. Some Narcissus species have grown to be 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 hundred years and by the late 19th century were an important commercial crop centred primarily on holland. Today narcissi are popular as slash blossoms so that as ornamental crops in private and public gardens. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering a variety of shapes and colours. Like other members of these family, narcissi create a number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested unintentionally. This property has been exploited for medicinal use within traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in books and art, narcissi are associated with a true number of themes in different cultures, ranging from fatality to fortune, and as symbols of spring. The daffodil is the nationwide blossom of Wales and the image of malignancy charities in many countries. The looks of the outdoors flowers in planting season is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering for an underground storage light. They regrow in the next year from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm depending on the species. Dwarf types such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might develop as high as 80 cm.
The crops are scapose, having an individual central leafless hollow flower stem (scape). Several blue-green or green, narrow, strap-shaped leaves come up from the bulb. The place stem usually bears a solitary rose, but occasionally a cluster of flowers (umbel). The flowers, which are conspicuous and white or yellowish usually, both or almost never renewable sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outside ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical shaped corona. The blossoms may hang down (pendent), or be erect. There are six pollen bearing stamens surrounding a central style. The ovary is inferior (below the floral parts) consisting of three chambers (trilocular). The berries contains a dry capsule that splits (dehisces) launching numerous black seed products.
The bulb is dormant following the leaves and flower stem die again and has contractile origins that yank it down further in to the soil. The bloom leaves and stem form in the bulb, to emerge the next season. Most varieties are dormant from summer season to later winter, flowering in the planting season, though a few types are fall months flowering.
