Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common names 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 the cup- or trumpet-shaped corona. The flowers are generally white or yellow (orange or green in garden varieties), with either uniform or contrasting colored tepals and corona.
Narcissus were well known in ancient civilisation, both medicinally and botanically, but formally described by Linnaeus in his Kinds Plantarum (1753). The genus is generally thought to have about ten areas with around 50 species. The amount of varieties has varied, depending about how they are labeled, credited to similarity between types and hybridization. The genus arose some right 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 anonymous, but it is often associated with a Greek expression for intoxicated (narcotic) and the misconception of the youth of this name who fell in love with his own representation. The English word 'daffodil' appears to be produced from "asphodel", with which it was commonly compared.
The species are local to meadows and woods in southern European countries and North Africa with a center of diversity in the Western 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 tend to be long-lived bulbs, which propagate by division, but are insect-pollinated also. Known pests, disorders and diseases include viruses, fungi, the larvae of flies, nematodes and mites. Some Narcissus species have become extinct, while others are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe after the 16th century and by the late 19th hundred years were an important commercial crop centred mostly on holland. Narcissi are popular as slice plants and since 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 categorized 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 ingested inadvertently. This property has been exploited for medicinal used in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in art work and books, narcissi are associated with a true number of themes in several cultures, ranging from loss of life to good fortune, and as symbols of planting season. The daffodil is the countrywide flower of Wales and the sign of cancer tumor charities in many countries. The looks of the outrageous flowers in spring is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering to a underground storage bulb. They regrow in the next time from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm depending on species. Dwarf types such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may increase as extra tall as 80 cm.
The crops are scapose, having an individual central leafless hollow flower stem (scape). Several green or blue-green, slim, strap-shaped leaves happen from the bulb. The flower stem usually bears a solitary blossom, but occasionally a cluster of plants (umbel). The bouquets, which can be usually conspicuous and white or yellow, sometimes both or rarely green, consist of 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 disk to conical shaped corona. The plants may hang up down (pendent), or be erect. A couple of six pollen bearing stamens encompassing a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The fruit consists of a dried out capsule that splits (dehisces) liberating numerous black seed products.
The bulb is dormant after the leaves and bloom stem die again and has contractile origins that pull it down further into the soil. The bloom stem and leaves form in the bulb, to emerge the next season. Most varieties are dormant from summer time to past due winter, flowering in the springtime, though a few species are autumn flowering.
