Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial crops 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 a cup- or trumpet-shaped corona. The bouquets are generally white or yellowish (orange or red in garden types), with either standard or contrasting colored tepals and corona.
Narcissus were popular in ancient civilisation, both medicinally and botanically, but formally defined by Linnaeus in his Varieties Plantarum (1753). The genus is generally considered to have about ten sections with approximately 50 species. The amount of kinds has assorted, depending on how they are labeled, due to similarity between hybridization and varieties. The genus arose time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact origin of the true name Narcissus is mysterious, but it is linked to a Greek term for intoxicated (narcotic) and the myth of the junior of this name who fell deeply in love with his own representation. The English term 'daffodil' is apparently derived from "asphodel", with which it was likened commonly.
The species are indigenous to meadows and woods in southern European countries and North Africa with a middle of variety in the European Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were unveiled in to the Far East to the tenth hundred years prior. Narcissi have a tendency 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, nematodes and mites. 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 initial times, but became ever more popular in Europe after the 16th century and by the later 19th hundred years were an important commercial crop centred mostly on holland. Narcissi are popular as slash plants as ornamental plant life in private and general population gardens today. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering a wide range of shapes and colours. 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 unintentionally. This property has been exploited for medicinal utilization in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in art and books, narcissi are associated with a number of themes in various cultures, ranging from loss of life to good fortune, and as symbols of springtime. The daffodil is the nationwide blossom of Wales and the icon of tumor charities in many countries. The appearance of the wild flowers in spring and coil is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to a underground storage light. They regrow in the following yr from brown-skinned ovoid bulbs with pronounced necks, and reach levels of 5-80 cm depending on the species. Dwarf species such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might expand as high as 80 cm.
The crops are scapose, having a single central leafless hollow blossom stem (scape). Several blue-green or green, slim, strap-shaped leaves occur from the bulb. The herb stem bears a solitary blossom, but sometimes a cluster of blooms (umbel). The plants, that are conspicuous and white or yellowish usually, sometimes both or seldom renewable, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outside ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical molded corona. The blossoms may hang up down (pendent), or be erect. A couple of six pollen bearing stamens encircling a central style. The ovary is inferior (below the floral parts) consisting of three chambers (trilocular). The fruit contains a dried out capsule that splits (dehisces) liberating numerous black seeds.
The bulb lies dormant after the leaves and flower stem die again and has contractile root base that draw it down further into the soil. The rose leaves and stem form in the light, to emerge the next season. Most species are dormant from warmer summer months to late winter, flowering in the spring and coil, though a few species are autumn flowering.
