Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plants 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 by the cup- or trumpet-shaped corona. The bouquets are usually white or yellow (orange or green in garden kinds), with either uniform or contrasting coloured corona and tepals.
Narcissus were popular in traditional civilisation, both and botanically medicinally, but formally defined by Linnaeus in his Varieties Plantarum (1753). The genus is generally thought to have about ten parts with roughly 50 species. The number of species has assorted, depending about how they are categorized, as a consequence to similarity between hybridization and species. 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 exact source of the name Narcissus is unfamiliar, but it is associated with a Greek term for intoxicated (narcotic) and the myth of the youth of this name who fell deeply in love with his own reflection. The English word 'daffodil' is apparently derived from "asphodel", with which it was likened commonly.
The varieties are native to meadows and woods in southern Europe and North Africa with a centre of variety in the European Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were unveiled into the ASIA to the tenth hundred years prior. Narcissi tend to be long-lived bulbs, which propagate by division, but are insect-pollinated also. Known pests, diseases and disorders include viruses, fungi, the larvae of flies, nematodes and mites. Some Narcissus species have become extinct, while some are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the initial times, but became ever more popular in Europe following the 16th century and by the past due 19th hundred years were an important commercial crop centred generally on the Netherlands. Today narcissi are popular as slash plants so when 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 categorised into divisions, covering a wide range of shapes and colours. Like other members of the family, narcissi produce a 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 use in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in literature and art, narcissi are associated with a number of themes in various cultures, ranging from death to good fortune, and as icons of springtime. The daffodil is the countrywide bloom of Wales and the sign of malignancy charities in many countries. The appearance of the outrageous flowers in spring is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering for an underground storage bulb. They regrow in the following calendar year from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm depending on the species. Dwarf types such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might increase as high as 80 cm.
The plant life are scapose, having an individual central leafless hollow bloom stem (scape). Several green or blue-green, narrow, strap-shaped leaves arise from the light bulb. The place stem bears a solitary rose, but once in a while a cluster of flowers (umbel). The blossoms, that happen to be usually conspicuous and white or yellowish, both or rarely 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 designed corona. The blooms may hang down (pendent), or be erect. There are six pollen bearing stamens adjoining a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The berries includes a dried up capsule that splits (dehisces) releasing numerous black seeds.
The bulb lies dormant following the leaves and blossom stem die again and has contractile root base that yank it down further into the soil. The blossom stem and leaves form in the light bulb, to emerge the next season. Most types are dormant from summer to later winter, flowering in the planting season, though a few species are autumn flowering.
