Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common names 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 by a cup- or trumpet-shaped corona. The blossoms are generally white or yellowish (orange or green in garden types), with either uniform or contrasting coloured tepals and corona.

Narcissus were popular in old civilisation, both and botanically medicinally, but formally explained by Linnaeus in his Varieties Plantarum (1753). The genus is generally thought to have about ten areas with approximately 50 species. The true volume of kinds has varied, depending 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 real name Narcissus is mysterious, but it is often linked to a Greek term for intoxicated (narcotic) and the misconception of the young ones of this name who fell in love with his own representation. The English word 'daffodil' is apparently derived from "asphodel", with which it was commonly likened.

The species are local to meadows and woods in southern European countries and North Africa with a centre of variety in the American Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were launched in to the Far East to the tenth century prior. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are insect-pollinated also. Known pests, disorders and diseases 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 earliest times, but became increasingly popular in Europe after the 16th century and by the past due 19th century were an important commercial crop centred primarily on the Netherlands. Narcissi are popular as slash bouquets so when ornamental plant life in private and open public gardens today. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering an array of colours and shapes. Like other members of their family, narcissi create a 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 use within traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in literature and skill, narcissi are associated with a number of themes in various cultures, ranging from death to good fortune, and as icons of springtime. The daffodil is the countrywide flower of Wales and the image of cancers charities in many countries. The appearance of the untamed flowers in spring and coil is associated with celebrations in many places.

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

The plants are scapose, having an individual central leafless hollow rose stem (scape). Several blue-green or green, thin, strap-shaped leaves arise from the bulb. The plant stem bears a solitary bloom, but occasionally a cluster of flowers (umbel). The blooms, that happen to be usually conspicuous and white or yellow, both or almost never renewable sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an external ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical formed corona. The flowers 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 super fruit includes a dry capsule that splits (dehisces) launching numerous black seeds.

The bulb lies dormant following the leaves and bloom stem die again and has contractile origins that take it down further in to the soil. The blossom leaves and stem form in the light, to emerge the next season. Most varieties are dormant from summer time to overdue winter, flowering in the spring, though a few kinds are fall flowering.
