Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial vegetation 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 a cup- or trumpet-shaped corona. The plants are usually white or yellowish (orange or green in garden varieties), with either standard or contrasting colored corona and tepals.
Narcissus were popular in historical civilisation, both medicinally and botanically, but formally identified by Linnaeus in his Varieties Plantarum (1753). The genus is normally thought to have about ten sections with about 50 species. The number of species has assorted, depending how they are classified, as a consequence to similarity between hybridization and kinds. The genus arose some time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise source of the name Narcissus is unknown, but it is often linked to a Greek phrase for intoxicated (narcotic) and the misconception of the children of this name who fell in love with his own reflection. The English word 'daffodil' is apparently produced from "asphodel", with which it was commonly compared.
The types are indigenous to meadows and woods in southern European countries and North Africa with a middle of variety in the Traditional western 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 tend 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, mites and nematodes. 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 after the 16th hundred years and by the late 19th century were an important commercial crop centred mostly on the Netherlands. Today narcissi are popular as chop bouquets so that as ornamental vegetation in private and public gardens. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are labeled 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 inadvertently. This property has been exploited for medicinal use within traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in skill and books, narcissi are associated with a true number of themes in several cultures, ranging from fatality to fortune, and as icons of spring. The daffodil is the countrywide blossom of Wales and the image of malignancy charities in many countries. The appearance of the wild flowers in springtime is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to a underground storage light bulb. They regrow in the next calendar year from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm depending on species. Dwarf types such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might expand as extra tall as 80 cm.
The vegetation are scapose, having an individual central leafless hollow blossom stem (scape). Several green or blue-green, narrow, strap-shaped leaves come up from the light. The place stem bears a solitary rose, but occasionally a cluster of blooms (umbel). The plants, which can be conspicuous and white or yellow usually, sometimes both or seldom inexperienced, contain 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 down (pendent), or be erect. You will discover six pollen bearing stamens encompassing a central style. The ovary is inferior (below the floral parts) consisting of three chambers (trilocular). The fruits includes a dried up capsule that splits (dehisces) liberating numerous black seeds.
The bulb is dormant following the leaves and rose stem die again and has contractile roots that yank it down further into the soil. The bloom leaves and stem form in the bulb, to emerge the next season. Most kinds are dormant from summer months to late winter, flowering in the spring, though a few varieties are fall months flowering.
