Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common names including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are used to describe all or some known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by a cup- or trumpet-shaped corona. The flowers are generally white or yellowish (orange or pink in garden kinds), with either standard or contrasting colored corona and tepals.

Narcissus were popular in old civilisation, both and botanically medicinally, but formally described by Linnaeus in his Kinds Plantarum (1753). The genus is normally considered to have about ten portions with approximately 50 species. The amount of types has mixed, depending on how they are categorized, due to similarity between hybridization and types. The genus arose some right time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact origins of the real name Narcissus is anonymous, but it is linked to a Greek expression for intoxicated (narcotic) and the myth of the youngsters of that name who fell in love with his own reflection. The English phrase 'daffodil' is apparently derived from "asphodel", with which it was likened commonly.

The kinds are local to meadows and woods in southern European countries and North Africa with a centre of diversity in the Western Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were introduced into the Far East prior to the tenth century. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are also insect-pollinated. Known pests, disorders and diseases include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have grown to be extinct, while some 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 overdue 19th century were an important commercial crop centred mainly on holland. Today narcissi are popular as trim flowers and since ornamental plants in private and general public gardens. 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 these family, narcissi create a true 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 use within traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in art work and literature, narcissi are associated with a number of themes in several cultures, ranging from fatality to good fortune, and as icons of springtime. The daffodil is the national bloom of Wales and the sign of cancer tumor charities in many countries. The appearance of the outrageous flowers in spring is associated with festivals in many places.

Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering for an underground storage bulb. They regrow in the following season from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm with regards to the species. Dwarf types such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may expand as high 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 arise from the bulb. The herb stem usually bears a solitary blossom, but occasionally a cluster of blooms (umbel). The flowers, that happen to be conspicuous and white or yellow usually, sometimes both or almost never inexperienced, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outside ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical molded corona. The flowers may suspend down (pendent), or be erect. There are six pollen bearing stamens surrounding a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The fruit includes a dried capsule that splits (dehisces) liberating numerous black seed products.

The bulb is dormant after the leaves and rose stem die back and has contractile origins that take it down further in to the soil. The bloom stem and leaves form in the bulb, to emerge the following season. Most species are dormant from summertime to late winter, flowering in the spring, though a few kinds are fall months flowering.
