Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common labels 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 way of a cup- or trumpet-shaped corona. The plants are usually white or yellow (orange or pink in garden varieties), with either even or contrasting colored tepals and corona.
Narcissus were popular in historical civilisation, both medicinally and botanically, but formally identified by Linnaeus in his Varieties Plantarum (1753). The genus is normally considered to have about ten areas with about 50 species. The number of species has varied, depending on how they are labeled, as a consequence to similarity between hybridization and varieties. 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 word for intoxicated (narcotic) and the myth of the youth of this name who fell deeply in love with his own reflection. The English term 'daffodil' appears to be derived from "asphodel", with which it was commonly compared.
The types 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 created into 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, disorders and diseases include viruses, fungi, the larvae of flies, nematodes and mites. Some Narcissus species have grown to be extinct, while some are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe following the 16th century and by the overdue 19th hundred years were an important commercial crop centred primarily on holland. Narcissi are popular as trim flowers as ornamental vegetation in private and open public gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a wide range of colours and shapes. Like other members of these family, narcissi create 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 within traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in art and literature, narcissi are associated with a number of themes in different cultures, ranging from death to fortune, and as icons of planting season. The daffodil is the countrywide blossom of Wales and the symbol of cancer tumor charities in many countries. The looks of the crazy flowers in planting season is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering for an underground storage light. They regrow in the following calendar year from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm depending on the species. Dwarf kinds such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may grow as large as 80 cm.
The plant life are scapose, having a single central leafless hollow flower stem (scape). Several blue-green or green, small, strap-shaped leaves occur from the light. The flower stem usually bears a solitary blossom, but sometimes a cluster of bouquets (umbel). The blooms, that are usually conspicuous and white or yellowish, both or almost never inexperienced sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outer ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical formed corona. The blooms may suspend down (pendent), or be erect. There are six pollen bearing stamens adjoining a central style. The ovary is second-rate (below the floral parts) consisting of three chambers (trilocular). The fruit includes a dried up capsule that splits (dehisces) liberating numerous black seeds.
The bulb is placed dormant after the leaves and flower stem die back and has contractile roots that take it down further into the soil. The flower leaves and stem form in the light, to emerge the next season. Most types are dormant from warmer summer months to past due winter, flowering in the spring and coil, though a few types are autumn flowering.
