Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common labels including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are 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 plants are usually white or yellow (orange or green in garden types), with either standard or contrasting coloured tepals and corona.
Narcissus were well known in historical civilisation, both medicinally and botanically, but formally described by Linnaeus in his Varieties Plantarum (1753). The genus is normally considered to have about ten portions with roughly 50 species. The true number of kinds has mixed, depending about how they are categorized, due to similarity between hybridization and kinds. The genus arose some right 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 mysterious, but it is often associated with a Greek expression for intoxicated (narcotic) and the myth of the junior of that name who fell in love with his own reflection. The English phrase 'daffodil' is apparently produced from "asphodel", with which it was commonly compared.
The types are native to meadows and woods in southern Europe and North Africa with a centre of diversity in the Traditional western 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 tend to be long-lived bulbs, which propagate by division, but are also insect-pollinated. Known pests, disorders and diseases include viruses, fungi, the larvae of flies, nematodes and mites. Some Narcissus species have grown to be extinct, while some 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 hundred years were an important commercial crop centred mainly on the Netherlands. Narcissi are popular as cut blooms so when ornamental crops in private and open public gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering an array of shapes and colours. Like other members of 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 utilization in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in art and literature, narcissi are associated with a number of themes in various cultures, ranging from loss of life to good fortune, and as icons of spring and coil. The daffodil is the nationwide rose of Wales and the symbol of tumor charities in many countries. The looks of the outdoors flowers in spring and coil is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering with an underground storage light. They regrow in the following year from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm with respect to the species. Dwarf kinds such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may develop as extra tall as 80 cm.
The plants are scapose, having a single central leafless hollow rose stem (scape). Several blue-green or green, slim, strap-shaped leaves arise from the bulb. The place stem usually bears a solitary blossom, but sometimes a cluster of blossoms (umbel). The blossoms, that are conspicuous and white or yellowish usually, sometimes both or almost never renewable, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outside ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical designed corona. The plants may suspend down (pendent), or be erect. There are six pollen bearing stamens encompassing a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The fruit contains a dried out capsule that splits (dehisces) launching numerous black seed products.
The bulb lays dormant following the leaves and bloom stem die back and has contractile roots that draw it down further in to the soil. The rose leaves and stem form in the light bulb, to emerge the next season. Most species are dormant from summer season to past due winter, flowering in the planting season, though a few species are fall months flowering.
