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 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 yellow (orange or red in garden varieties), with either even or contrasting colored tepals and corona.
Narcissus were popular in historic civilisation, both medicinally and botanically, but formally defined by Linnaeus in his Species Plantarum (1753). The genus is generally thought to have about ten areas with around 50 species. The true number of kinds has varied, depending about how they are categorised, thanks 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 regions of southwest Europe. The exact source of the real name Narcissus is unfamiliar, but it is linked to a Greek term for intoxicated (narcotic) and the misconception of the children of this name who fell in love with his own reflection. The English word 'daffodil' appears to be derived from "asphodel", with which it was commonly compared.
The types 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, disorders and diseases include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have grown to be extinct, while others are threatened by increasing urbanisation and tourism.
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 late 19th century were an important commercial crop centred primarily on holland. Today narcissi are popular as chop flowers as ornamental plant life in private and general public gardens. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering an array of colours and shapes. 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 accidentally ingested. This property has been exploited for medicinal used in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in art and literature, narcissi are associated with a number of themes in several cultures, ranging from death to good fortune, and as symbols of spring and coil. The daffodil is the nationwide blossom of Wales and the sign of cancer charities in many countries. The appearance of the outdoors 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 an underground storage light bulb. They regrow in the next season from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm depending on the species. Dwarf species such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may grow as extra tall as 80 cm.
The plant life are scapose, having an individual central leafless hollow blossom stem (scape). Several green or blue-green, slim, strap-shaped leaves arise from the bulb. The flower stem usually bears a solitary rose, but sometimes a cluster of flowers (umbel). The bouquets, that are conspicuous and white or yellowish usually, both or seldom inexperienced sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an exterior ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical shaped corona. The plants may suspend down (pendent), or be erect. There are six pollen bearing stamens bordering a central style. The ovary is second-rate (below the floral parts) consisting of three chambers (trilocular). The berry includes a dried out capsule that splits (dehisces) liberating numerous black seed products.
The bulb lays dormant following the leaves and blossom stem die back and has contractile root base that pull it down further in to the soil. The bloom leaves and stem form in the bulb, to emerge the following season. Most varieties are dormant from summer to late winter, flowering in the springtime, though a few kinds are autumn flowering.
