Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial vegetation 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 yellow (orange or pink in garden varieties), with either uniform or contrasting colored tepals and corona.
Narcissus were popular in old civilisation, both medicinally and botanically, but formally referred to by Linnaeus in his Varieties Plantarum (1753). The genus is generally considered to have about ten sections with roughly 50 species. The amount of varieties has varied, depending on how they are categorised, 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 source of the name Narcissus is unfamiliar, but it is often linked to a Greek term for intoxicated (narcotic) and the myth of the junior of that name who fell in love with his own representation. The English word 'daffodil' appears to be produced from "asphodel", with which it was likened commonly.
The types are indigenous to meadows and woods in southern European countries and North Africa with a center of diversity in the American Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were introduced in to the Far East prior to 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 become extinct, while some are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became ever more popular in Europe following the 16th century and by the overdue 19th hundred years were an important commercial crop centred mainly on holland. Today narcissi are popular as lower plants and as ornamental crops in private and public gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a wide range of shapes and colours. Like other members with their family, narcissi produce a true number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested inadvertently. 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 literature and fine art, narcissi are associated with a true number of themes in different cultures, ranging from loss of life to good fortune, and as symbols of spring and coil. The daffodil is the countrywide blossom of Wales and the icon of cancer tumor charities in many countries. The appearance of the crazy flowers in spring is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to a underground storage light. They regrow in the following season from brown-skinned ovoid bulbs with pronounced necks, and reach levels of 5-80 cm with respect to the species. Dwarf varieties such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may develop as tall as 80 cm.
The plants are scapose, having a single central leafless hollow bloom stem (scape). Several blue-green or green, slim, strap-shaped leaves arise from the bulb. The herb stem usually bears a solitary blossom, but sometimes a cluster of flowers (umbel). The blooms, that are usually conspicuous and white or yellowish, sometimes both or hardly ever green, 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 disc to conical designed corona. The plants may hang down (pendent), or be erect. You will find six pollen bearing stamens surrounding a central style. The ovary is second-rate (below the floral parts) consisting of three chambers (trilocular). The fruits consists of a dried up capsule that splits (dehisces) launching numerous black seed products.
The bulb sits dormant following the leaves and rose stem die back and has contractile origins that draw it down further into the soil. The flower stem and leaves form in the light bulb, to emerge the following season. Most types are dormant from summer season to late winter, flowering in the planting season, though a few types are autumn flowering.
