Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plant life 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 the cup- or trumpet-shaped corona. The blossoms are usually white or yellow (orange or green in garden kinds), with either standard or contrasting coloured tepals and corona.
Narcissus were well known in historic civilisation, both and botanically medicinally, but formally referred to by Linnaeus in his Species Plantarum (1753). The genus is generally thought to have about ten parts with around 50 species. The true amount of varieties has varied, depending on how they are grouped, thanks to similarity between hybridization and species. The genus arose some right time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise source of the name Narcissus is undiscovered, but it is often linked to a Greek phrase for intoxicated (narcotic) and the misconception of the youth of that name who fell in love with his own representation. The English word 'daffodil' appears to be produced from "asphodel", with which it was likened commonly.
The kinds are local to meadows and woods in southern European countries and North Africa with a centre of diversity in the Traditional western Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were introduced in to the Far East prior to the tenth century. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are insect-pollinated also. Known pests, diseases and disorders include viruses, fungi, the larvae of flies, nematodes and mites. Some Narcissus species have become extinct, while others 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 past due 19th century were an important commercial crop centred mostly on holland. Narcissi are popular as lower flowers and as ornamental plants in private and general population gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering an array of shapes and colours. Like other members of their family, narcissi create a true number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested accidentally. This property has been exploited for medicinal use in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in books and artwork, narcissi are associated with a true number of themes in various cultures, ranging from fatality to good fortune, and as symbols of springtime. The daffodil is the nationwide bloom of Wales and the image of cancer charities in many countries. The looks of the outrageous flowers in spring is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering to an underground storage light. They regrow in the following season from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm depending on the species. Dwarf kinds such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might expand as extra tall as 80 cm.
The vegetation are scapose, having a single central leafless hollow blossom stem (scape). Several blue-green or green, narrow, strap-shaped leaves happen from the light bulb. The flower stem bears a solitary bloom, but once in a while a cluster of flowers (umbel). The plants, that are usually conspicuous and white or yellow, sometimes both or rarely renewable, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outer ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical molded corona. The plants may hang up down (pendent), or be erect. You will discover six pollen bearing stamens adjoining a central style. The ovary is second-rate (below the floral parts) consisting of three chambers (trilocular). The berries involves a dry capsule that splits (dehisces) liberating numerous black seed products.
The bulb is placed dormant after the leaves and blossom stem die back again and has contractile origins that yank it down further into the soil. The flower leaves and stem form in the light, to emerge the following season. Most varieties are dormant from summer season to past due winter, flowering in the spring and coil, though a few varieties are fall months flowering.
