Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common labels 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 bouquets are usually white or yellow (orange or green in garden varieties), with either uniform or contrasting colored tepals and corona.
Narcissus were well known in historical civilisation, both and botanically medicinally, but formally described by Linnaeus in his Types Plantarum (1753). The genus is generally considered to have about ten portions with around 50 species. The true variety of varieties has varied, depending on how they are grouped, due to similarity between hybridization and species. The genus arose some time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise origin of the true name Narcissus is mysterious, but it is linked to a Greek phrase for intoxicated (narcotic) and the myth of the children of this name who fell in love with his own representation. The English word 'daffodil' is apparently produced from "asphodel", with which it was likened commonly.
The species are native to meadows and woods in southern Europe and North Africa with a center of variety in the American Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were created into the Far East to the tenth hundred years prior. Narcissi tend 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, mites and nematodes. 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 overdue 19th hundred years were an important commercial crop centred primarily on the Netherlands. Today narcissi are popular as cut blooms so that as ornamental plants in private and open public gardens. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are classified 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 utilization in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in skill and literature, narcissi are associated with a number of themes in several cultures, ranging from death to fortune, and as symbols of springtime. The daffodil is the nationwide flower of Wales and the sign of cancers charities in many countries. The looks of the untamed flowers in spring is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to an underground storage light. They regrow in the next calendar year from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm with regards to the species. Dwarf types such as N. asturiensis have a maximum level 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 blue-green or green, narrow, strap-shaped leaves happen from the light bulb. The herb stem usually bears a solitary blossom, but sometimes a cluster of plants (umbel). The plants, which are usually conspicuous and white or yellowish, sometimes both or rarely inexperienced, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an exterior ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical molded corona. The blossoms may hang down (pendent), or be erect. A couple of six pollen bearing stamens bordering a central style. The ovary is substandard (below the floral parts) consisting of three chambers (trilocular). The berry involves a dried out capsule that splits (dehisces) launching numerous black seeds.
The bulb is situated dormant following the leaves and flower stem die again and has contractile roots that yank it down further into the soil. The rose leaves and stem form in the light, to emerge the following season. Most species are dormant from summer season to late winter, flowering in the springtime, though a few species are fall months flowering.
