Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plant life 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 way of a cup- or trumpet-shaped corona. The plants are usually white or yellow (orange or pink in garden types), with either even or contrasting coloured tepals and corona.

Narcissus were popular in early civilisation, both medicinally and botanically, but formally described by Linnaeus in his Species Plantarum (1753). The genus is generally thought to have about ten sections with roughly 50 species. The true variety of varieties has assorted, depending how they are categorised, a consequence of to similarity between hybridization and kinds. The genus arose some right 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 anonymous, but it is linked to a Greek expression for intoxicated (narcotic) and the myth of the junior of this name who fell in love with his own representation. The English expression 'daffodil' is apparently produced from "asphodel", with which it was likened commonly.

The varieties are local to meadows and woods in southern European countries and North Africa with a center of variety in the American Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were unveiled into the ASIA to the tenth hundred years 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 grown to be extinct, while some are threatened by increasing tourism and urbanisation.

Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe following the 16th century and by the later 19th hundred years were an important commercial crop centred mainly on holland. Today narcissi are popular as cut flowers and since ornamental plant life in private and public gardens. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a wide range of shapes and colours. Like other members of these family, narcissi create 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 use within traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in books and fine art, narcissi are associated with a number of themes in various cultures, ranging from death to good fortune, and as icons of spring and coil. The daffodil is the national bloom of Wales and the image of cancer tumor charities in many countries. The looks of the wild 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 to the underground storage light bulb. They regrow in the next yr from brown-skinned ovoid light 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 height of 5-8 cm, while Narcissus tazetta might increase as tall as 80 cm.

The vegetation are scapose, having an individual central leafless hollow blossom stem (scape). Several green or blue-green, slim, strap-shaped leaves come up from the light. The flower stem usually bears a solitary flower, but occasionally a cluster of flowers (umbel). The flowers, which are usually conspicuous and white or yellowish, both or hardly ever inexperienced sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outside ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical molded corona. The flowers may hang up down (pendent), or be erect. You can find six pollen bearing stamens surrounding a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The berry contains a dry out capsule that splits (dehisces) releasing numerous black seeds.

The bulb is situated dormant after the leaves and rose stem die again and has contractile origins that draw it down further into the soil. The flower leaves and stem form in the light, to emerge the next season. Most types are dormant from summer to past due winter, flowering in the springtime, though a few kinds are fall flowering.
