Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial crops 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 known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by the cup- or trumpet-shaped corona. The plants are usually white or yellowish (orange or red in garden varieties), with either standard or contrasting coloured corona and tepals.

Narcissus were popular in historical civilisation, both medicinally and botanically, but formally identified by Linnaeus in his Kinds Plantarum (1753). The genus is generally considered to have about ten sections with roughly 50 species. The amount of species has assorted, depending on how they are labeled, due 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 source of the name Narcissus is unidentified, but it is often linked to a Greek expression for intoxicated (narcotic) and the misconception of the youth of that name who fell in love with his own representation. The English word 'daffodil' is apparently derived from "asphodel", with which it was likened commonly.

The species are native to meadows and woods in southern European countries and North Africa with a middle of variety in the American Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were presented into the ASIA to the tenth hundred years prior. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are insect-pollinated also. Known pests, diseases and disorders include viruses, fungi, the larvae of flies, mites and nematodes. 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 following the 16th century and by the late 19th century were an important commercial crop centred primarily on holland. Narcissi are popular as slice blossoms and since ornamental vegetation in private and open public gardens today. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a variety of shapes and colours. Like other members of these family, narcissi create a 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 skill, narcissi are associated with a true number of themes in several cultures, ranging from death to good fortune, and as symbols of planting season. The daffodil is the nationwide bloom of Wales and the mark of cancers charities in many countries. The looks of the crazy flowers in spring and coil is associated with celebrations in many places.

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

The plants are scapose, having an individual central leafless hollow rose stem (scape). Several blue-green or green, small, strap-shaped leaves happen from the light bulb. The place stem bears a solitary bloom, but once in a while a cluster of blossoms (umbel). The flowers, that happen to be conspicuous and white or yellowish usually, sometimes both or hardly ever renewable, consist of 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 blooms may suspend down (pendent), or be erect. You can find six pollen bearing stamens encompassing a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The fruits includes a dried out capsule that splits (dehisces) liberating numerous black seeds.

The bulb sits dormant following the leaves and rose stem die back and has contractile roots that move it down further into the soil. The bloom stem and leaves form in the light bulb, to emerge the next season. Most types are dormant from summer to later winter, flowering in the spring and coil, though a few types are autumn flowering.
