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 being used to describe all or some known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by a cup- or trumpet-shaped corona. The plants are usually white or yellow (orange or green in garden varieties), with either uniform or contrasting colored corona and tepals.
Narcissus were popular in old civilisation, both and botanically medicinally, but formally described by Linnaeus in his Species Plantarum (1753). The genus is normally considered to have about ten parts with around 50 species. The number of varieties has assorted, depending on how they are grouped, as a consequence to similarity between hybridization and kinds. 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 precise origins of the real name Narcissus is unfamiliar, but it is linked to a Greek phrase for intoxicated (narcotic) and the myth of the youth of that name who fell in love with his own representation. The English word 'daffodil' is apparently produced from "asphodel", with which it was commonly likened.
The kinds are indigenous to meadows and woods in southern Europe and North Africa with a center of variety in the Traditional western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were launched in to the Far East to the tenth century prior. 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, nematodes and mites. Some Narcissus species have become extinct, while others 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 century and by the later 19th hundred years were an important commercial crop centred mainly on holland. Narcissi are popular as chop flowers and since ornamental vegetation in private and public gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering a wide range of colours and shapes. Like other members with their 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 utilization in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in art and books, narcissi are associated with a number of themes in different cultures, ranging from loss of life to fortune, and as icons of spring and coil. The daffodil is the national bloom of Wales and the image of tumors charities in many countries. The appearance of the crazy flowers in planting season is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering for an underground storage light bulb. They regrow in the next season from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf varieties such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may increase as extra tall as 80 cm.
The vegetation are scapose, having an individual central leafless hollow rose stem (scape). Several green or blue-green, small, strap-shaped leaves happen from the light. The seed stem bears a solitary flower, but once in a while a cluster of plants (umbel). The plants, that are usually conspicuous and white or yellowish, 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 exterior ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical shaped corona. The flowers may hang up down (pendent), or be erect. There are six pollen bearing stamens bordering a central style. The ovary is substandard (below the floral parts) consisting of three chambers (trilocular). The super fruit contains a dried out capsule that splits (dehisces) liberating numerous black seeds.
The bulb is situated dormant following the leaves and rose stem die back again and has contractile root base that take it down further in to the soil. The flower stem and leaves form in the light bulb, to emerge the following season. Most types are dormant from summer to past due winter, flowering in the spring, though a few types are autumn flowering.
