Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plants 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 a 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 popular in ancient civilisation, both and botanically medicinally, but formally defined by Linnaeus in his Types Plantarum (1753). The genus is generally considered to have about ten areas with around 50 species. The number of varieties has assorted, depending about how they are categorised, thanks to similarity between hybridization and types. The genus arose some right amount of 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 associated with a Greek phrase for intoxicated (narcotic) and the misconception of the youngsters of this name who fell deeply in love with his own representation. The English word 'daffodil' is apparently derived from "asphodel", with which it was commonly likened.

The varieties are native to meadows and woods in southern European countries and North Africa with a centre of diversity in the European Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were introduced into the Far East before 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, nematodes and mites. Some Narcissus species have become extinct, while some are threatened by increasing urbanisation and tourism.

Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe after the 16th century and by the later 19th century were an important commercial crop centred mainly on the Netherlands. Today narcissi are popular as trim plants as ornamental crops in private and general population 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 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 accidentally ingested. 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 artwork and literature, 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 sign of cancers charities in many countries. The looks of the outrageous flowers in spring is associated with festivals in many places.

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

The plants are scapose, having a single central leafless hollow rose stem (scape). Several green or blue-green, small, strap-shaped leaves occur from the light bulb. The herb stem bears a solitary blossom, but once in a while a cluster of blooms (umbel). The bouquets, which can be usually conspicuous and white or yellow, sometimes both or seldom renewable, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outer ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical formed corona. The blossoms may suspend down (pendent), or be erect. There are six pollen bearing stamens encircling a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The berries consists of a dried up capsule that splits (dehisces) releasing numerous black seeds.

The bulb is placed dormant after the leaves and rose stem die back again and has contractile roots that pull it down further into the soil. The flower stem and leaves form in the bulb, to emerge the next season. Most species are dormant from summertime to past due winter, flowering in the spring and coil, though a few types are fall flowering.
