Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common brands 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 plants are generally white or yellow (orange or green in garden types), with either standard or contrasting colored tepals and corona.

Narcissus were well known 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 portions with roughly 50 species. The true number of varieties has assorted, depending about how they are classified, 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 origins of the real name Narcissus is unfamiliar, but it is associated with a Greek expression for intoxicated (narcotic) and the misconception of the junior of that name who fell in love with his own representation. The English phrase 'daffodil' is apparently derived from "asphodel", with which it was likened commonly.

The kinds are native to meadows and woods in southern Europe and North Africa with a center of variety in the Traditional western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were introduced in to the Far East prior to the tenth century. 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 others are threatened by increasing tourism and urbanisation.

Historical accounts suggest narcissi have been cultivated from the earliest times, but became ever more popular in Europe following the 16th century and by the late 19th hundred years were an important commercial crop centred generally on holland. Today narcissi are popular as chop flowers and as ornamental plant life in private and public gardens. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering an array of shapes and colours. 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 unintentionally. This property has been exploited for medicinal used in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in art and books, narcissi are associated with a true number of themes in various cultures, ranging from fatality to good fortune, and as symbols of spring. The daffodil is the nationwide bloom of Wales and the symbol of cancers charities in many countries. The looks of the crazy flowers in spring is associated with celebrations in many places.

Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to the underground storage bulb. They regrow in the next time from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm with regards to the species. Dwarf kinds such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might expand as high as 80 cm.

The plants are scapose, having a single central leafless hollow blossom stem (scape). Several green or blue-green, thin, strap-shaped leaves happen from the light bulb. The plant stem bears a solitary flower, but sometimes a cluster of plants (umbel). The plants, which can be usually conspicuous and white or yellowish, sometimes both or hardly ever inexperienced, 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 molded corona. The blossoms may hang up down (pendent), or be erect. You will find six pollen bearing stamens encircling a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The fruits includes a dried out capsule that splits (dehisces) launching numerous black seeds.

The bulb lies dormant after the leaves and blossom stem die back again and has contractile origins that move it down further into the soil. The flower stem and leaves form in the light bulb, to emerge the following season. Most varieties are dormant from summer months to overdue winter, flowering in the planting season, though a few kinds are fall months flowering.
