Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common labels 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 by the cup- or trumpet-shaped corona. The flowers are usually white or yellowish (orange or green in garden kinds), with either uniform or contrasting coloured tepals and corona.

Narcissus were well known in historic civilisation, both and botanically medicinally, but formally detailed by Linnaeus in his Varieties Plantarum (1753). The genus is generally thought to have about ten sections with around 50 species. The true number of varieties has mixed, depending how they are categorized, thanks to similarity between hybridization and types. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The exact origin of the real name Narcissus is mysterious, but it is linked to a Greek expression for intoxicated (narcotic) and the myth of the youngsters of this name who fell in love with his own representation. The English term 'daffodil' appears to be derived from "asphodel", with which it was likened commonly.

The types are indigenous to meadows and woods in southern Europe and North Africa with a center of variety in the European Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were launched in to the Far East to the tenth hundred years prior. Narcissi tend to be long-lived bulbs, which propagate by division, but are also insect-pollinated. Known pests, diseases and disorders include viruses, fungi, the larvae of flies, mites and nematodes. 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 initial times, but became ever more popular in Europe following the 16th century and by the later 19th century were an important commercial crop centred primarily on holland. Today narcissi are popular as trim bouquets and as ornamental plant life in private and general public gardens. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a variety of shapes and colours. Like other members of their 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 utilization in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in books and skill, narcissi are associated with a number of themes in several cultures, ranging from loss of life to fortune, and as symbols of spring. The daffodil is the national bloom of Wales and the sign of cancer tumor charities in many countries. The looks of the crazy flowers in springtime is associated with festivals in many places.

Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to the underground storage light. They regrow in the next season from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm with respect to the species. Dwarf varieties such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might increase as high as 80 cm.

The plants are scapose, having a single central leafless hollow rose stem (scape). Several green or blue-green, thin, strap-shaped leaves occur from the light bulb. The plant stem bears a solitary flower, but once in a while a cluster of blossoms (umbel). The flowers, that happen to be usually conspicuous and white or yellowish, both or rarely inexperienced sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outside ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical molded corona. The bouquets may suspend down (pendent), or be erect. A couple of six pollen bearing stamens encompassing a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The berry includes a dried capsule that splits (dehisces) liberating numerous black seed products.

The bulb is dormant after the leaves and blossom stem die again and has contractile root base that yank it down further in to the soil. The bloom 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 springtime, though a few species are fall flowering.
