Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common brands including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are being used to describe all or some members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by the cup- or trumpet-shaped corona. The flowers are generally white or yellow (orange or red in garden varieties), with either standard or contrasting coloured tepals and corona.
Narcissus were popular in historical civilisation, both and botanically medicinally, but formally detailed by Linnaeus in his Species Plantarum (1753). The genus is generally considered to have about ten parts with roughly 50 species. The true amount of types has varied, depending how they are classified, thanks 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 exact origin of the true name Narcissus is unknown, but it is linked to a Greek word for intoxicated (narcotic) and the misconception of the youth of that name who fell in love with his own reflection. The English expression 'daffodil' appears to be produced from "asphodel", with which it was compared commonly.
The kinds 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 cultivated and wild plants have naturalised widely, and were introduced into the Far East before the tenth century. Narcissi have a tendency 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, nematodes and mites. Some Narcissus species have grown to be extinct, while some 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 late 19th hundred years were an important commercial crop centred mostly on the Netherlands. Today narcissi are popular as slash blossoms and as ornamental plant life in private and general population 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 colours and shapes. Like other members with their family, narcissi create a true 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 used in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in artwork and literature, narcissi are associated with a true number of themes in various cultures, ranging from fatality to fortune, and as icons of spring and coil. The daffodil is the countrywide bloom of Wales and the symbol of tumors charities in many countries. The looks of the outdoors flowers in planting season is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to the underground storage light. They regrow in the following time from brown-skinned ovoid bulbs with pronounced necks, and reach heights 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 large as 80 cm.
The vegetation are scapose, having an individual central leafless hollow bloom stem (scape). Several blue-green or green, thin, strap-shaped leaves arise from the light bulb. The seed stem bears a solitary blossom, but occasionally a cluster of blossoms (umbel). The blooms, which are conspicuous and white or yellowish usually, both or almost never green sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an exterior ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical designed corona. The blossoms may suspend down (pendent), or be erect. You will find six pollen bearing stamens surrounding a central style. The ovary is second-rate (below the floral parts) consisting of three chambers (trilocular). The super fruit includes a dry capsule that splits (dehisces) liberating numerous black seeds.
The bulb sits dormant after the leaves and bloom stem die back and has contractile origins that draw it down further in to the soil. The flower leaves and stem form in the bulb, to emerge the next season. Most types are dormant from summer months to later winter, flowering in the spring and coil, though a few kinds are autumn flowering.
