Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common labels including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are being used to describe all or some 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 yellowish (orange or red in garden types), with either standard or contrasting colored tepals and corona.
Narcissus were well known in traditional civilisation, both and botanically medicinally, but formally referred to by Linnaeus in his Species Plantarum (1753). The genus is normally considered to have about ten parts with roughly 50 species. The amount of varieties has mixed, depending how they are grouped, 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 real name Narcissus is mysterious, but it is often associated with a Greek phrase for intoxicated (narcotic) and the misconception of the young ones of this name who fell in love with his own representation. The English term 'daffodil' appears to be produced from "asphodel", with which it was commonly compared.
The species are local to meadows and woods in southern European countries and North Africa with a center of variety in the Western Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were introduced into the Far East before the tenth century. Narcissi have a tendency 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 grown to be extinct, while others are threatened by increasing tourism and urbanisation.
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 past due 19th hundred years were an important commercial crop centred mostly on holland. Today narcissi are popular as cut blooms so when ornamental plant life in private and open public gardens. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering an array of colours and shapes. Like other members of the 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 within traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in art work and books, narcissi are associated with a true number of themes in several cultures, ranging from fatality to fortune, and as icons of spring. The daffodil is the countrywide rose of Wales and the icon of tumors charities in many countries. The appearance of the outrageous flowers in spring is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to a underground storage light. They regrow in the next yr from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm depending on species. Dwarf varieties such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may grow as tall as 80 cm.
The plants are scapose, having an individual central leafless hollow rose stem (scape). Several green or blue-green, thin, strap-shaped leaves come up from the light bulb. The plant stem usually bears a solitary blossom, but sometimes a cluster of flowers (umbel). The flowers, that happen to be conspicuous and white or yellowish usually, both or almost never renewable sometimes, consist of 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 disc to conical shaped corona. The blooms may suspend down (pendent), or be erect. There are six pollen bearing stamens adjoining a central style. The ovary is second-rate (below the floral parts) consisting of three chambers (trilocular). The super fruit includes a dry capsule that splits (dehisces) liberating numerous black seed products.
The bulb is situated dormant following the leaves and rose stem die back and has contractile root base that take it down further in to the soil. The flower leaves and stem form in the light, to emerge the following season. Most types are dormant from warmer summer months to past due winter, flowering in the planting season, though a few species are fall months flowering.
