Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common titles including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are 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 flowers are usually white or yellow (orange or green in garden kinds), with either uniform or contrasting coloured corona and tepals.

Narcissus were well known in old civilisation, both medicinally and botanically, but formally detailed by Linnaeus in his Types Plantarum (1753). The genus is normally considered to have about ten sections with approximately 50 species. The true variety of types has varied, depending how they are categorised, as a consequence to similarity between hybridization and kinds. The genus arose some time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact origins of the true name Narcissus is unknown, but it is often linked to a Greek phrase for intoxicated (narcotic) and the misconception of the youngsters of this name who fell in love with his own reflection. The English expression 'daffodil' appears to be derived from "asphodel", with which it was likened commonly.

The varieties are indigenous to meadows and woods in southern European countries and North Africa with a centre of variety in the American Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were released in to the Far East to the tenth hundred years prior. Narcissi tend 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, mites and nematodes. Some Narcissus species have become extinct, while some are threatened by increasing urbanisation and tourism.

Historical accounts suggest narcissi have been cultivated from the earliest times, but became ever more popular in Europe after the 16th hundred years and by the past due 19th century were an important commercial crop centred mainly on the Netherlands. Narcissi are popular as chop flowers so that as ornamental vegetation in private and general population gardens today. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering a variety 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 unintentionally. This property has been exploited for medicinal used in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in art and books, narcissi are associated with a number of themes in different cultures, ranging from fatality to good fortune, and as icons of springtime. The daffodil is the national flower of Wales and the image of cancers charities in many countries. The looks of the outrageous flowers in spring is associated with celebrations in many places.

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

The vegetation are scapose, having a single central leafless hollow bloom stem (scape). Several green or blue-green, small, strap-shaped leaves come up from the light bulb. The herb stem bears a solitary bloom, but sometimes a cluster of flowers (umbel). The bouquets, that are usually conspicuous and white or yellow, both or hardly ever green sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an external ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical molded corona. The plants may hang down (pendent), or be erect. You will discover six pollen bearing stamens surrounding a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The fruit involves a dried up capsule that splits (dehisces) releasing numerous black seed products.

The bulb sits dormant after the leaves and flower stem die back and has contractile root base that draw it down further into the soil. The rose leaves and stem form in the bulb, to emerge the next season. Most species are dormant from summer to overdue winter, flowering in the springtime, though a few kinds are autumn flowering.
