Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial crops 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 way of a cup- or trumpet-shaped corona. The bouquets are generally white or yellowish (orange or pink in garden varieties), with either uniform or contrasting colored corona and tepals.

Narcissus were well known in ancient civilisation, both medicinally and botanically, but formally described by Linnaeus in his Species Plantarum (1753). The genus is normally considered to have about ten areas with approximately 50 species. The number of types has assorted, depending on how they are labeled, due to similarity between hybridization and types. The genus arose some time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The exact origins of the name Narcissus is undiscovered, but it is often associated with a Greek expression for intoxicated (narcotic) and the misconception of the children of this name who fell in love with his own representation. The English phrase 'daffodil' appears to be derived from "asphodel", with which it was commonly likened.

The kinds are indigenous to meadows and woods in southern Europe and North Africa with a center of variety in the European Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were unveiled in to the Far East to the tenth hundred years prior. Narcissi tend 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 urbanisation and tourism.

Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe after the 16th hundred years and by the later 19th century were an important commercial crop centred primarily on the Netherlands. Narcissi are popular as lower flowers and as ornamental plant life in private and open public gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering a variety of colours and shapes. Like other members of their family, narcissi produce a true 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 utilization in traditional healing and has led to 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 death to fortune, and as icons of spring and coil. The daffodil is the nationwide blossom of Wales and the icon of cancer tumor charities in many countries. The looks of the untamed flowers in springtime is associated with festivals in many places.

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

The vegetation are scapose, having a single central leafless hollow rose stem (scape). Several blue-green or green, slim, strap-shaped leaves happen from the light bulb. The herb stem usually bears a solitary blossom, but sometimes a cluster of bouquets (umbel). The plants, that happen to be conspicuous and white or yellowish 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 molded corona. The plants may hang up down (pendent), or be erect. There are six pollen bearing stamens encompassing 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) liberating numerous black seed products.

The bulb lies dormant after the leaves and blossom stem die back and has contractile roots that yank it down further in to the soil. The rose stem and leaves form in the bulb, to emerge the next season. Most kinds are dormant from summertime to late winter, flowering in the springtime, though a few kinds are fall months flowering.
