Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial vegetation 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 with a cup- or trumpet-shaped corona. The flowers are usually white or yellowish (orange or red in garden types), with either standard or contrasting coloured tepals and corona.

Narcissus were well known in historical civilisation, both and botanically medicinally, but formally described by Linnaeus in his Kinds Plantarum (1753). The genus is normally thought to have about ten areas with roughly 50 species. The amount of types has assorted, depending on how they are classified, thanks to similarity between hybridization and kinds. The genus arose 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 mysterious, but it is linked to a Greek term for intoxicated (narcotic) and the misconception of the junior of this name who fell in love with his own representation. The English word 'daffodil' appears to be derived from "asphodel", with which it was commonly compared.

The kinds are native to meadows and woods in southern Europe and North Africa with a centre of variety in the Western Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were unveiled 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 also insect-pollinated. 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 tourism and urbanisation.

Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe following the 16th century and by the past due 19th century were an important commercial crop centred mainly on holland. Narcissi are popular as lower blossoms and since ornamental plant life in private and public gardens today. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering an array of shapes and colours. 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 ingested inadvertently. This property has been exploited for medicinal utilization in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in books and art work, narcissi are associated with a true number of themes in several cultures, ranging from loss of life to good fortune, and as symbols of springtime. The daffodil is the national bloom of Wales and the symbol of cancer charities in many countries. The looks of the outdoors flowers in spring is associated with festivals in many places.

Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering for an underground storage light bulb. They regrow in the following 12 months from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm depending on the species. Dwarf types such as N. asturiensis have a maximum elevation 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 bloom stem (scape). Several blue-green or green, thin, strap-shaped leaves happen from the bulb. The seed stem usually bears a solitary blossom, but occasionally a cluster of bouquets (umbel). The blossoms, that are usually conspicuous and white or yellowish, both or almost never renewable sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an external ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical molded corona. The bouquets may hang up down (pendent), or be erect. You can find six pollen bearing stamens bordering a central style. The ovary is inferior (below the floral parts) consisting of three chambers (trilocular). The fruits includes a dried capsule that splits (dehisces) launching numerous black seeds.

The bulb lays dormant following the leaves and blossom stem die back and has contractile origins that draw it down further in to the soil. The blossom stem and leaves form in the bulb, to emerge the next season. Most types are dormant from warmer summer months to later winter, flowering in the springtime, though a few species are autumn flowering.
