Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common names 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 with a cup- or trumpet-shaped corona. The blossoms are usually white or yellow (orange or pink in garden kinds), with either standard or contrasting colored corona and tepals.
Narcissus were well known in old civilisation, both and botanically medicinally, but formally detailed by Linnaeus in his Types Plantarum (1753). The genus is normally considered to have about ten parts with around 50 species. The true number of kinds has mixed, depending on how they are categorised, anticipated to similarity between types and hybridization. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact origins of the name Narcissus is unfamiliar, but it is often associated with a Greek word for intoxicated (narcotic) and the misconception of the young ones of that name who fell in love with his own representation. The English phrase 'daffodil' is apparently derived from "asphodel", with which it was likened commonly.
The kinds are indigenous to meadows and woods in southern Europe and North Africa with a centre of diversity in the American Mediterranean, the Iberian peninsula particularly. Both wild and cultivated 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 also insect-pollinated. Known pests, diseases and disorders include viruses, fungi, the larvae of flies, nematodes and mites. Some Narcissus species have become extinct, while some are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became ever more popular in Europe following the 16th century and by the late 19th hundred years were an important commercial crop centred primarily on holland. Narcissi are popular as trim blossoms and since ornamental vegetation in private and open public gardens today. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering an array of shapes and colours. Like other members with their family, narcissi produce 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 used in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in art work and books, narcissi are associated with a number of themes in various cultures, ranging from death to good fortune, and as icons of spring. The daffodil is the national bloom of Wales and the image of tumors charities in many countries. The appearance of the crazy 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 the underground storage light. They regrow in the next 12 months from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm depending on species. Dwarf varieties such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might expand as tall as 80 cm.
The plant life are scapose, having a single central leafless hollow flower stem (scape). Several green or blue-green, narrow, strap-shaped leaves come up from the light. The vegetable stem bears a solitary flower, but occasionally a cluster of blossoms (umbel). The blossoms, that happen to be conspicuous and white or yellowish usually, sometimes both or seldom renewable, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an exterior ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical formed corona. The blooms may hang up down (pendent), or be erect. You will find six pollen bearing stamens bordering a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The berries involves a dried out capsule that splits (dehisces) liberating numerous black seeds.
The bulb lies dormant following the leaves and flower stem die again and has contractile roots that take it down further in to the soil. The rose leaves and stem form in the bulb, to emerge the following season. Most kinds are dormant from summer to later winter, flowering in the spring and coil, though a few kinds are fall months flowering.
