Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common brands 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 red in garden varieties), with either uniform or contrasting colored tepals and corona.

Narcissus were well known in old civilisation, both and botanically medicinally, but formally explained by Linnaeus in his Kinds Plantarum (1753). The genus is generally thought to have about ten sections with about 50 species. The true quantity of varieties has varied, depending on how they are classified, a consequence of to similarity between hybridization and types. The genus arose 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 undiscovered, but it is linked to a Greek word for intoxicated (narcotic) and the myth of the youngsters of that name who fell in love with his own reflection. The English expression 'daffodil' appears to be derived from "asphodel", with which it was commonly compared.

The types are local to meadows and woods in southern European countries and North Africa with a centre of variety in the Western Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were unveiled in to the ASIA to the tenth century 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, mites and nematodes. Some Narcissus species have become extinct, while others are threatened by increasing urbanisation and tourism.

Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe following the 16th hundred years and by the late 19th century were an important commercial crop centred primarily on the Netherlands. Narcissi are popular as slash bouquets as ornamental plant life 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 classified 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 inadvertently. 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 skill, narcissi are associated with a true number of themes in several cultures, ranging from loss of life to good fortune, and as icons of planting season. The daffodil is the countrywide flower of Wales and the symbol of cancer tumor charities in many countries. The appearance of the outrageous flowers in spring is associated with celebrations in many places.

Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering to the underground storage bulb. They regrow in the following 12 months from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf kinds such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may expand as extra tall as 80 cm.

The plant life are scapose, having an individual central leafless hollow rose stem (scape). Several green or blue-green, small, strap-shaped leaves happen from the light bulb. The seed stem bears a solitary rose, but occasionally a cluster of plants (umbel). The plants, that are usually conspicuous and white or yellow, both or almost never green sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outer ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical designed corona. The bouquets may suspend down (pendent), or be erect. There are six pollen bearing stamens surrounding a central style. The ovary is second-rate (below the floral parts) consisting of three chambers (trilocular). The berry consists of a dry capsule that splits (dehisces) releasing numerous black seeds.

The bulb lies dormant following the leaves and blossom stem die back and has contractile roots that pull it down further into the soil. The bloom stem and leaves form in the light bulb, to emerge the following season. Most varieties are dormant from summer months to past due winter, flowering in the spring and coil, though a few kinds are fall months flowering.
