Narcissus /n?:r's?s?s/ is a genus of predominantly 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 members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by the cup- or trumpet-shaped corona. The plants are usually white or yellowish (orange or red in garden varieties), with either uniform or contrasting coloured tepals and corona.
Narcissus were popular in historic civilisation, both medicinally and botanically, but formally explained by Linnaeus in his Species Plantarum (1753). The genus is generally thought to have about ten parts with about 50 species. The number of kinds has mixed, depending about how they are categorised, a consequence of to similarity between hybridization and varieties. The genus arose some right amount of time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise source of the name Narcissus is unidentified, but it is often linked to a Greek term for intoxicated (narcotic) and the myth of the junior of that name who fell in love with his own representation. The English phrase 'daffodil' appears to be produced from "asphodel", with which it was compared commonly.
The species are indigenous to meadows and woods in southern European countries and North Africa with a centre of variety in the European Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were introduced in to the ASIA to the tenth hundred years prior. Narcissi have a tendency 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 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 following the 16th hundred years and by the late 19th hundred years were an important commercial crop centred generally on the Netherlands. Narcissi are popular as chop flowers and as ornamental plants in private and general population gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering an array of colours and shapes. Like other members of these 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 used in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in literature and fine art, narcissi are associated with a true number of themes in several cultures, ranging from death to fortune, and as symbols of planting season. The daffodil is the nationwide bloom of Wales and the mark of tumor charities in many countries. The looks of the untamed flowers in springtime is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to the underground storage light. They regrow in the next 12 months from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm with respect to the species. Dwarf varieties such as N. asturiensis have a maximum level 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 blue-green or green, narrow, strap-shaped leaves occur from the bulb. The flower stem usually bears a solitary flower, but once in a while a cluster of flowers (umbel). The bouquets, which are conspicuous and white or yellowish usually, sometimes both or hardly ever renewable, 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 disk to conical shaped corona. The flowers may hang up down (pendent), or be erect. A couple of six pollen bearing stamens bordering a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The fruits contains a dried capsule that splits (dehisces) launching numerous black seed products.
The bulb lies dormant following the leaves and blossom stem die back and has contractile root base that pull it down further into the soil. The rose stem and leaves form in the bulb, to emerge the next season. Most varieties are dormant from summer months to overdue winter, flowering in the planting season, though a few kinds are fall months flowering.
