Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common names including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are used to describe all or some members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted with a cup- or trumpet-shaped corona. The plants are usually white or yellowish (orange or green in garden kinds), with either even or contrasting colored tepals and corona.
Narcissus were popular in traditional civilisation, both medicinally and botanically, but formally explained by Linnaeus in his Species Plantarum (1753). The genus is normally thought to have about ten sections with around 50 species. The number of species has mixed, depending how they are labeled, due to similarity between hybridization and varieties. The genus arose time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise source of the name Narcissus is mysterious, but it is associated with a Greek term for intoxicated (narcotic) and the myth of the youth of that name who fell in love with his own reflection. The English phrase 'daffodil' is apparently produced from "asphodel", with which it was likened commonly.
The varieties are local to meadows and woods in southern Europe and North Africa with a middle of variety in the American Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were introduced into the Far East prior to the tenth century. Narcissi tend 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 urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe following the 16th hundred years and by the overdue 19th hundred years were an important commercial crop centred mainly on holland. Today narcissi are popular as chop flowers and since ornamental plant life in private and open public gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering a wide range of colours and shapes. Like other members of their family, narcissi produce 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 used in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in literature and art work, narcissi are associated with a true number of themes in different cultures, ranging from loss of life to good fortune, and as symbols of planting season. The daffodil is the countrywide flower of Wales and the image of cancers charities in many countries. The looks of the wild flowers in springtime is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to a underground storage light bulb. They regrow in the following year from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm with regards to the species. Dwarf varieties such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might increase as large as 80 cm.
The vegetation are scapose, having a single central leafless hollow flower stem (scape). Several green or blue-green, thin, strap-shaped leaves arise from the light. The plant stem bears a solitary blossom, but occasionally a cluster of flowers (umbel). The bouquets, that are conspicuous and white or yellow usually, both or seldom inexperienced sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outside ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical shaped corona. The blooms may hang up down (pendent), or be erect. A couple of six pollen bearing stamens encompassing a central style. The ovary is substandard (below the floral parts) consisting of three chambers (trilocular). The berries includes a dry capsule that splits (dehisces) liberating numerous black seeds.
The bulb sits dormant after the leaves and flower stem die again and has contractile root base that pull it down further in to the soil. The flower leaves and stem form in the light, to emerge the next season. Most varieties are dormant from summertime to later winter, flowering in the spring, though a few kinds are autumn flowering.
