Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common names 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 way of a cup- or trumpet-shaped corona. The blossoms are usually white or yellow (orange or red in garden varieties), with either even or contrasting coloured tepals and corona.
Narcissus were popular in historic civilisation, both medicinally and botanically, but formally explained by Linnaeus in his Species Plantarum (1753). The genus is normally thought to have about ten portions with approximately 50 species. The amount of varieties has varied, depending how they are classified, due to similarity between hybridization and types. The genus arose time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise source of the name Narcissus is unknown, but it is associated with a Greek phrase for intoxicated (narcotic) and the myth of the young ones of this name who fell in love with his own representation. The English phrase 'daffodil' appears to be produced from "asphodel", with which it was compared commonly.
The varieties are local to meadows and woods in southern European countries and North Africa with a centre of diversity in the European Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were presented in to the ASIA to the tenth hundred years prior. Narcissi tend to be long-lived bulbs, which propagate by division, but are also insect-pollinated. 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 tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became ever more popular in Europe following the 16th hundred years and by the late 19th hundred years were an important commercial crop centred generally on holland. Today narcissi are popular as chop flowers so that as ornamental plant life in private and general 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 a wide range of colours and shapes. 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 accidentally. This property has been exploited for medicinal used in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in art work and literature, narcissi are associated with a number of themes in various cultures, ranging from death to good fortune, and as symbols of planting season. The daffodil is the nationwide flower of Wales and the symbol of cancers charities in many countries. The appearance of the crazy 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 an underground storage light bulb. They regrow in the next season from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf species such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may develop as high as 80 cm.
The crops are scapose, having an individual central leafless hollow rose stem (scape). Several blue-green or green, narrow, strap-shaped leaves arise from the bulb. The herb stem usually bears a solitary bloom, but sometimes a cluster of plants (umbel). The blooms, that happen to be conspicuous and white or yellow usually, both or almost never inexperienced sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an external ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical molded corona. The bouquets may suspend down (pendent), or be erect. A couple of six pollen bearing stamens adjoining a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The super fruit contains a dry capsule that splits (dehisces) launching numerous black seeds.
The bulb sits dormant after the leaves and rose stem die again and has contractile root base that draw it down further in to the soil. The rose stem and leaves form in the light, to emerge the following season. Most species are dormant from summertime to overdue winter, flowering in the planting season, though a few types are autumn flowering.
