Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plants 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 with a cup- or trumpet-shaped corona. The blooms are generally white or yellow (orange or green in garden kinds), with either uniform or contrasting colored tepals and corona.
Narcissus were popular in early civilisation, both and botanically medicinally, but formally explained by Linnaeus in his Varieties Plantarum (1753). The genus is normally considered to have about ten parts with around 50 species. The true quantity of types has varied, depending on how they are classified, anticipated to similarity between kinds and hybridization. The genus arose some time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The exact origins of the name Narcissus is unidentified, but it is often linked to a Greek term for intoxicated (narcotic) and the misconception of the youngsters of this name who fell in love with his own reflection. The English word 'daffodil' is apparently derived from "asphodel", with which it was commonly compared.
The kinds are local to meadows and woods in southern European countries and North Africa with a centre of variety in the European Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were introduced in to 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, 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 increasingly popular in Europe following the 16th century and by the past due 19th century were an important commercial crop centred mostly on the Netherlands. Narcissi are popular as lower bouquets and since ornamental plant life in private and public gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering a wide range of shapes and colours. Like other members of these family, narcissi create 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 treating Alzheimer's dementia. Long celebrated in skill and books, narcissi are associated with a number of themes in several cultures, ranging from death to good fortune, and as icons of planting season. The daffodil is the nationwide bloom of Wales and the icon of cancers 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 for an underground storage light bulb. They regrow in the following calendar year from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf varieties such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may grow as high as 80 cm.
The vegetation are scapose, having a single central leafless hollow bloom stem (scape). Several blue-green or green, thin, strap-shaped leaves come up from the light. The flower stem bears a solitary flower, but occasionally a cluster of blossoms (umbel). The bouquets, that happen to be conspicuous and white or yellow usually, both or hardly ever inexperienced 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 disk to conical shaped corona. The blooms may hang up down (pendent), or be erect. There are six pollen bearing stamens encircling a central style. The ovary is second-rate (below the floral parts) consisting of three chambers (trilocular). The berries involves a dried up capsule that splits (dehisces) liberating numerous black seed products.
The bulb is dormant following the leaves and bloom stem die again and has contractile root base that draw it down further in to the soil. The blossom stem and leaves form in the bulb, to emerge the next season. Most varieties are dormant from summer to past due winter, flowering in the spring, though a few species are fall flowering.
