Narcissus /n?:r's?s?s/ is a genus of mostly 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 blooms are usually white or yellow (orange or green in garden types), with either uniform or contrasting colored corona and tepals.

Narcissus were well known in early civilisation, both and botanically medicinally, but formally referred to by Linnaeus in his Varieties Plantarum (1753). The genus is generally thought to have about ten areas with approximately 50 species. The number of kinds has varied, depending on how they are categorised, anticipated to similarity between kinds and hybridization. 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 often linked to a Greek term for intoxicated (narcotic) and the misconception of the children of this name who fell in love with his own representation. The English term 'daffodil' appears to be produced from "asphodel", with which it was likened commonly.

The kinds are indigenous to meadows and woods in southern European countries and North Africa with a center of variety in the European Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were unveiled into the ASIA to the tenth hundred years prior. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are insect-pollinated also. 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 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 overdue 19th century were an important commercial crop centred generally on the Netherlands. Today narcissi are popular as trim bouquets and as ornamental plant life in private and general population gardens. The long history of breeding has resulted in thousands 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 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 use in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in skill and books, narcissi are associated with a number of themes in different cultures, ranging from fatality to good fortune, and as symbols of spring. The daffodil is the countrywide blossom of Wales and the mark of cancer charities in many countries. The looks of the outrageous flowers in springtime is associated with festivals in many places.

Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering for an underground storage light bulb. They regrow in the following yr from brown-skinned ovoid bulbs with pronounced necks, and reach levels of 5-80 cm depending on species. Dwarf kinds such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might develop as high as 80 cm.

The crops are scapose, having a single central leafless hollow bloom stem (scape). Several blue-green or green, narrow, strap-shaped leaves occur from the bulb. The place stem bears a solitary rose, but occasionally a cluster of plants (umbel). The bouquets, which can be conspicuous and white or yellow usually, sometimes both or almost never green, 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 blooms may hang up down (pendent), or be erect. You will discover six pollen bearing stamens surrounding a central style. The ovary is substandard (below the floral parts) consisting of three chambers (trilocular). The fruits involves a dried up capsule that splits (dehisces) releasing numerous black seed products.

The bulb is situated dormant after the leaves and rose stem die again and has contractile roots that take it down further into the soil. The rose leaves and stem form in the bulb, to emerge the following season. Most kinds are dormant from summer season to late winter, flowering in the spring and coil, though a few species are autumn flowering.
