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 used to describe all or some known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted with a cup- or trumpet-shaped corona. The plants are usually white or yellowish (orange or red in garden types), with either uniform or contrasting colored tepals and corona.
Narcissus were popular in historic civilisation, both medicinally and botanically, but formally explained by Linnaeus in his Types Plantarum (1753). The genus is normally considered to have about ten parts with around 50 species. The true variety of species has assorted, depending about how they are labeled, thanks to similarity between hybridization and varieties. The genus arose some 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 often linked to a Greek word for intoxicated (narcotic) and the myth of the young ones of that name who fell deeply in love with his own reflection. The English phrase 'daffodil' appears to be produced from "asphodel", with which it was likened commonly.
The varieties are native to meadows and woods in southern European countries and North Africa with a center of variety in the European Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were released into the Far East to the tenth century 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, mites and nematodes. Some Narcissus species have become 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 hundred years and by the later 19th century were an important commercial crop centred mostly on the Netherlands. Narcissi are popular as chop flowers so that as ornamental vegetation in private and general public gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering an array 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 use within traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in art and books, narcissi are associated with a true number of themes in different cultures, ranging from loss of life to fortune, and as symbols of spring. The daffodil is the national flower of Wales and the image of cancer tumor charities in many countries. The appearance of the untamed flowers in spring is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering with an underground storage light. They regrow in the following calendar year from brown-skinned ovoid bulbs with pronounced necks, and reach levels of 5-80 cm depending on the species. Dwarf species such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may increase as extra tall as 80 cm.
The plant life are scapose, having an individual central leafless hollow rose stem (scape). Several green or blue-green, narrow, strap-shaped leaves arise from the light bulb. The seed stem bears a solitary rose, but once in a while a cluster of plants (umbel). The plants, that are usually conspicuous and white or yellow, both or hardly ever renewable sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outer ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical designed corona. The flowers may hang down (pendent), or be erect. There are six pollen bearing stamens encircling a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The fruits consists of a dried out capsule that splits (dehisces) launching numerous black seeds.
The bulb lies dormant after the leaves and rose stem die back again and has contractile roots that take it down further in to the soil. The flower leaves and stem form in the light, to emerge the following season. Most species are dormant from summer time to overdue winter, flowering in the spring and coil, though a few types are fall months flowering.
