Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plant life 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 with a cup- or trumpet-shaped corona. The flowers are generally white or yellowish (orange or green in garden kinds), with either uniform or contrasting coloured tepals and corona.

Narcissus were well known in ancient civilisation, both medicinally and botanically, but formally defined by Linnaeus in his Species Plantarum (1753). The genus is normally considered to have about ten areas with roughly 50 species. The true number of kinds has assorted, depending on how they are classified, a consequence of to similarity between hybridization and species. 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 origin of the name Narcissus is unidentified, but it is often associated with a Greek expression for intoxicated (narcotic) and the misconception of the youngsters of that name who fell in love with his own representation. The English term 'daffodil' is apparently produced from "asphodel", with which it was commonly compared.

The species are native to meadows and woods in southern European countries and North Africa with a center of variety in the European Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were introduced in to the Far East to the tenth century prior. Narcissi tend 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 others are threatened by increasing urbanisation and tourism.

Historical accounts suggest narcissi have been cultivated from the initial times, but became ever more popular in Europe following the 16th hundred years and by the overdue 19th hundred years were an important commercial crop centred generally on the Netherlands. Narcissi are popular as cut bouquets as ornamental plants in private and general population gardens today. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a wide range of colours and shapes. Like other members with their family, narcissi produce a number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested accidentally. This property has been exploited for medicinal use in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in books and fine art, narcissi are associated with a true number of themes in several cultures, ranging from death to good fortune, and as icons of springtime. The daffodil is the national bloom of Wales and the icon of tumor charities in many countries. The appearance of the outrageous flowers in spring is associated with celebrations in many places.

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

The crops are scapose, having a single central leafless hollow flower stem (scape). Several green or blue-green, slim, strap-shaped leaves happen from the light bulb. The herb stem bears a solitary bloom, but once in a while a cluster of plants (umbel). The blooms, which can be conspicuous and white or yellowish usually, sometimes both or rarely inexperienced, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an external ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical shaped corona. The flowers may hang up down (pendent), or be erect. You can find six pollen bearing stamens adjoining a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The super fruit involves a dried capsule that splits (dehisces) releasing numerous black seeds.

The bulb is situated dormant following the leaves and rose stem die again and has contractile origins that pull it down further into the soil. The blossom leaves and stem form in the light bulb, to emerge the following season. Most varieties are dormant from summer season to later winter, flowering in the planting season, though a few species are fall flowering.
