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

Narcissus were well known in early civilisation, both medicinally and botanically, but formally defined by Linnaeus in his Species Plantarum (1753). The genus is normally considered to have about ten areas with around 50 species. The true number of types has mixed, depending about how they are categorised, thanks 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 origins of the name Narcissus is unfamiliar, but it is often associated with a Greek word for intoxicated (narcotic) and the myth of the children of this name who fell deeply in love with his own representation. The English word 'daffodil' appears to be derived from "asphodel", with which it was compared commonly.

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

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 past due 19th hundred years were an important commercial crop centred mainly on the Netherlands. Today narcissi are popular as cut flowers so that as ornamental crops in private and general public gardens. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering a wide range 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 ingested unintentionally. This property has been exploited for medicinal utilization in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in literature and artwork, narcissi are associated with a number of themes in several cultures, ranging from loss of life to fortune, and as icons of springtime. The daffodil is the national rose of Wales and the icon of malignancy charities in many countries. The appearance of the outdoors flowers in planting season is associated with celebrations in many places.

Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering with an underground storage bulb. They regrow in the next calendar year from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm with respect to the species. Dwarf varieties such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might expand as high as 80 cm.

The crops are scapose, having an individual central leafless hollow bloom stem (scape). Several green or blue-green, small, strap-shaped leaves come up from the bulb. The flower stem usually bears a solitary rose, but sometimes a cluster of flowers (umbel). The flowers, which can be usually conspicuous and white or yellowish, sometimes both or seldom renewable, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outer ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical shaped corona. The blossoms may hang down (pendent), or be erect. A couple of six pollen bearing stamens bordering a central style. The ovary is substandard (below the floral parts) consisting of three chambers (trilocular). The fruit involves a dried capsule that splits (dehisces) launching numerous black seeds.

The bulb is dormant following the leaves and rose stem die back and has contractile roots that move it down further in to the soil. The flower stem and leaves form in the light, to emerge the following season. Most kinds are dormant from summertime to overdue winter, flowering in the spring and coil, though a few types are fall flowering.
