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 with a cup- or trumpet-shaped corona. The bouquets are generally white or yellow (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 described by Linnaeus in his Varieties Plantarum (1753). The genus is generally thought to have about ten portions with around 50 species. The true amount of species has varied, depending how they are grouped, credited to similarity between kinds and hybridization. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise origins of the name Narcissus is unfamiliar, but it is associated with a Greek term for intoxicated (narcotic) and the myth of the junior of this name who fell in love with his own reflection. The English expression 'daffodil' is apparently produced from "asphodel", with which it was compared commonly.

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

Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe after the 16th century and by the later 19th hundred years were an important commercial crop centred mostly on holland. Narcissi are popular as cut bouquets so that ornamental vegetation in private and open public gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering an array of colours and shapes. Like other members with 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 treatment of Alzheimer's dementia. Long celebrated in literature and artwork, narcissi are associated with a number of themes in several cultures, ranging from fatality to fortune, and as symbols of spring and coil. The daffodil is the countrywide flower of Wales and the sign of cancer charities in many countries. The appearance of the untamed flowers in springtime is associated with festivals in many places.

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

The crops are scapose, having a single central leafless hollow flower stem (scape). Several green or blue-green, narrow, strap-shaped leaves arise from the light bulb. The vegetable stem bears a solitary flower, but sometimes a cluster of flowers (umbel). The blossoms, that are conspicuous and white or yellow usually, sometimes both or seldom inexperienced, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outside ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical shaped corona. The plants may hang down (pendent), or be erect. A couple of six pollen bearing stamens encompassing a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The berry contains a dry out capsule that splits (dehisces) liberating numerous black seeds.

The bulb lays dormant after the leaves and rose stem die back again and has contractile origins that take 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 season to overdue winter, flowering in the spring, though a few types are autumn flowering.
