Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common titles 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 with a cup- or trumpet-shaped corona. The blooms are generally white or yellowish (orange or pink in garden kinds), with either uniform or contrasting colored corona and tepals.

Narcissus were well known in early civilisation, both and botanically medicinally, but formally identified by Linnaeus in his Kinds Plantarum (1753). The genus is normally thought to have about ten sections with roughly 50 species. The true amount of species has mixed, depending on how they are classified, thanks to similarity between hybridization and species. The genus arose 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 unknown, but it is often linked to a Greek word for intoxicated (narcotic) and the myth of the junior of that name who fell in love with his own representation. The English expression 'daffodil' is apparently produced from "asphodel", with which it was commonly likened.

The varieties are indigenous to meadows and woods in southern Europe and North Africa with a centre of variety in the Western Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were presented into 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 initial times, but became increasingly popular in Europe following the 16th hundred years and by the later 19th hundred years were an important commercial crop centred mainly on holland. Narcissi are popular as trim blooms as ornamental vegetation in private and general population gardens today. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering a wide range of colours and shapes. Like other members of the family, narcissi produce 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 used in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in art and literature, narcissi are associated with a true number of themes in various cultures, ranging from death to good fortune, and as symbols of spring and coil. The daffodil is the countrywide rose of Wales and the icon of cancer charities in many countries. The looks of the crazy flowers in planting season is associated with festivals in many places.

Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering for an underground storage bulb. They regrow in the following yr from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm with respect to the species. Dwarf kinds such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may develop as large as 80 cm.

The plants are scapose, having a single central leafless hollow blossom stem (scape). Several green or blue-green, thin, strap-shaped leaves occur from the bulb. The flower stem usually bears a solitary rose, but once in a while a cluster of blossoms (umbel). The plants, which are conspicuous and white or yellowish usually, both or seldom inexperienced sometimes, 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 disk to conical formed corona. The blossoms may hang up down (pendent), or be erect. You will find six pollen bearing stamens encompassing a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The berry contains a dried capsule that splits (dehisces) releasing numerous black seeds.

The bulb is placed dormant following the leaves and rose stem die again and has contractile root base that yank it down further into the soil. The flower stem and leaves form in the light, to emerge the following season. Most kinds are dormant from warmer summer months to late winter, flowering in the spring and coil, though a few types are autumn flowering.
