Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common titles 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 bouquets are generally white or yellow (orange or red in garden types), with either even or contrasting coloured tepals and corona.
Narcissus were popular in traditional civilisation, both medicinally and botanically, but formally detailed by Linnaeus in his Kinds Plantarum (1753). The genus is normally considered to have about ten portions with approximately 50 species. The true volume of species has varied, depending how they are grouped, 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 origins of the real name Narcissus is unfamiliar, but it is linked to a Greek term 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' appears to be produced from "asphodel", with which it was commonly likened.
The species are local to meadows and woods in southern European countries and North Africa with a center of diversity in the European Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were released 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, 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 following the 16th hundred years and by the later 19th hundred years were an important commercial crop centred generally on holland. Today narcissi are popular as cut plants so when ornamental crops in private and open public gardens. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering a variety of shapes and colours. 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 led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in artwork and literature, narcissi are associated with a true number of themes in various cultures, ranging from death to fortune, and as symbols of planting season. The daffodil is the nationwide rose of Wales and the icon of tumor charities in many countries. The appearance of the outdoors flowers in springtime is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to the underground storage light. They regrow in the next calendar year from brown-skinned ovoid 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 extra tall as 80 cm.
The plant life are scapose, having an individual central leafless hollow rose stem (scape). Several green or blue-green, small, strap-shaped leaves happen from the light. The flower stem usually bears a solitary flower, but occasionally a cluster of plants (umbel). The plants, which can be usually conspicuous and white or yellow, sometimes both or hardly ever inexperienced, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an external ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical designed corona. The flowers may hang down (pendent), or be erect. There are six pollen bearing stamens surrounding a central style. The ovary is inferior (below the floral parts) consisting of three chambers (trilocular). The berries involves a dried up capsule that splits (dehisces) launching numerous black seeds.
The bulb is situated dormant after the leaves and blossom stem die back again and has contractile root base that move it down further in to the soil. The bloom leaves and stem form in the light bulb, to emerge the next season. Most species are dormant from summer time to past due winter, flowering in the springtime, though a few varieties are autumn flowering.
