Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common brands 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 a cup- or trumpet-shaped corona. The blooms are generally white or yellow (orange or green in garden kinds), with either uniform or contrasting coloured corona and tepals.
Narcissus were popular in early civilisation, both medicinally and botanically, but formally detailed by Linnaeus in his Varieties Plantarum (1753). The genus is normally thought to have about ten sections with about 50 species. The amount of species has assorted, depending on how they are labeled, as a consequence to similarity between hybridization and kinds. The genus arose time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The exact origins of the name Narcissus is unidentified, but it is linked to a Greek expression for intoxicated (narcotic) and the myth of the youngsters of this name who fell deeply in love with his own reflection. The English word 'daffodil' is apparently produced from "asphodel", with which it was commonly likened.
The kinds are native to meadows and woods in southern European countries and North Africa with a middle of diversity 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 tend 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, 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 increasingly popular in Europe following the 16th hundred years and by the later 19th hundred years were an important commercial crop centred generally on holland. Narcissi are popular as lower bouquets and since ornamental crops in private and open public gardens today. 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 colours and shapes. Like other members of their family, narcissi create a number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested unintentionally. This property has been exploited for medicinal use in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in artwork and literature, narcissi are associated with a number of themes in several cultures, ranging from loss of life to good fortune, and as icons of planting season. The daffodil is the national flower of Wales and the icon of tumor charities in many countries. The looks of the wild flowers in springtime is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to the underground storage light bulb. They regrow in the following year from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf types such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might expand as tall as 80 cm.
The vegetation are scapose, having an individual central leafless hollow rose stem (scape). Several blue-green or green, slim, strap-shaped leaves happen from the light bulb. The herb stem bears a solitary blossom, but occasionally a cluster of blooms (umbel). The blossoms, which are conspicuous and white or yellowish usually, both or hardly ever renewable sometimes, contain 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 disc to conical molded corona. The blooms may hang down (pendent), or be erect. A couple of six pollen bearing stamens bordering a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The fruit contains a dry out capsule that splits (dehisces) releasing numerous black seed products.
The bulb is placed dormant after the leaves and flower stem die again and has contractile origins that take it down further into the soil. The flower stem and leaves form in the light, to emerge the following season. Most species are dormant from summer time to overdue winter, flowering in the spring, though a few types are fall flowering.
