Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common labels 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 generally white or yellowish (orange or green in garden kinds), with either standard or contrasting coloured tepals and corona.

Narcissus were well known in old civilisation, both and botanically medicinally, but formally defined by Linnaeus in his Varieties Plantarum (1753). The genus is normally considered to have about ten areas with roughly 50 species. The true range of kinds has varied, depending about how they are classified, due to similarity between hybridization and species. The genus arose some time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise origin of the name Narcissus is unfamiliar, but it is associated with a Greek expression for intoxicated (narcotic) and the misconception of the young ones of this name who fell in love with his own reflection. The English term 'daffodil' is apparently produced from "asphodel", with which it was compared commonly.

The varieties are local to meadows and woods in southern European countries and North Africa with a middle of variety in the Western Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were released into the ASIA 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 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 following the 16th century and by the overdue 19th hundred years were an important commercial crop centred generally on the Netherlands. Narcissi are popular as chop blossoms and as ornamental crops in private and open public gardens today. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a variety of colours and shapes. 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 ingested accidentally. This property has been exploited for medicinal used in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in literature and art work, narcissi are associated with a number of themes in different cultures, ranging from fatality to fortune, and as symbols of springtime. The daffodil is the countrywide blossom of Wales and the icon of cancer charities in many countries. The looks of the wild flowers in springtime is associated with celebrations 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 year from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm depending on species. Dwarf types such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may increase as extra tall as 80 cm.

The crops are scapose, having an individual central leafless hollow flower stem (scape). Several blue-green or green, narrow, strap-shaped leaves occur from the light bulb. The herb stem usually bears a solitary flower, but once in a while a cluster of flowers (umbel). The bouquets, that happen to be conspicuous and white or yellowish usually, 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 external ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical shaped corona. The bouquets may hang down (pendent), or be erect. You will find six pollen bearing stamens encompassing a central style. The ovary is second-rate (below the floral parts) consisting of three chambers (trilocular). The berries contains a dry capsule that splits (dehisces) liberating numerous black seeds.

The bulb sits dormant after the leaves and bloom stem die again and has contractile roots that draw it down further into the soil. The blossom leaves and stem form in the light, to emerge the following season. Most varieties are dormant from warmer summer months to late winter, flowering in the spring, though a few types are fall flowering.
