Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common titles 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 plants are generally white or yellowish (orange or red in garden kinds), with either standard or contrasting colored corona and tepals.
Narcissus were well known in ancient civilisation, both medicinally and botanically, but formally described by Linnaeus in his Types Plantarum (1753). The genus is normally thought to have about ten sections with roughly 50 species. The true quantity of kinds has assorted, depending on how they are categorised, scheduled to similarity between kinds and hybridization. The genus arose time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The exact origin of the true name Narcissus is mysterious, but it is associated with a Greek phrase for intoxicated (narcotic) and the myth of the young ones of that name who fell in love with his own reflection. The English phrase 'daffodil' is apparently derived from "asphodel", with which it was commonly compared.
The varieties are native to meadows and woods in southern European countries and North Africa with a centre of variety in the European Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were introduced in to the Far East before the tenth century. 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 grown to be extinct, while others are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe after the 16th hundred years and by the later 19th hundred years were an important commercial crop centred primarily on the Netherlands. Today narcissi are popular as lower plants so that as ornamental crops in private and general public gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a variety of colours and shapes. Like other members of the 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 used in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in fine art and literature, narcissi are associated with a true number of themes in different cultures, ranging from fatality to good fortune, and as icons of spring. The daffodil is the nationwide flower of Wales and the symbol of tumors charities in many countries. The looks of the outrageous flowers in spring and coil is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering to the underground storage light. They regrow in the following season from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm depending on species. Dwarf varieties such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may develop as high as 80 cm.
The plants are scapose, having an individual central leafless hollow blossom stem (scape). Several blue-green or green, small, strap-shaped leaves arise from the light. The plant stem usually bears a solitary blossom, but sometimes a cluster of flowers (umbel). The bouquets, which can be 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 exterior ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical molded corona. The plants may hang up down (pendent), or be erect. A couple of six pollen bearing stamens bordering a central style. The ovary is substandard (below the floral parts) consisting of three chambers (trilocular). The super fruit involves a dry capsule that splits (dehisces) launching numerous black seed products.
The bulb sits dormant after the leaves and bloom stem die again and has contractile root base that yank 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 past due winter, flowering in the spring and coil, though a few varieties are fall months flowering.
