Narcissus /n?:r's?s?s/ is a genus of predominantly 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 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 yellow (orange or green in garden types), with either even or contrasting coloured corona and tepals.
Narcissus were popular in ancient civilisation, both medicinally and botanically, but formally defined by Linnaeus in his Species Plantarum (1753). The genus is normally thought to have about ten portions with approximately 50 species. The true amount of kinds has assorted, depending on how they are categorised, as a consequence to similarity between hybridization and varieties. The genus arose time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact origins of the name Narcissus is unidentified, but it is often associated with a Greek phrase for intoxicated (narcotic) and the myth of the junior of this name who fell in love with his own representation. The English term 'daffodil' appears to be produced from "asphodel", with which it was likened commonly.
The kinds are local to meadows and woods in southern Europe and North Africa with a middle of variety 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 before the tenth century. Narcissi tend 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 grown to be extinct, while some are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the initial times, but became ever more popular in Europe after the 16th century and by the past due 19th century were an important commercial crop centred mainly on the Netherlands. Narcissi are popular as slice blooms so that ornamental plant life in private and public gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering a variety of shapes and colours. Like other members of their family, narcissi create a 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 use within traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in artwork and books, narcissi are associated with a number of themes in several cultures, ranging from fatality to good fortune, and as icons of springtime. The daffodil is the nationwide flower of Wales and the image of cancer charities in many countries. The looks of the untamed flowers in spring and coil is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering with an underground storage bulb. They regrow in the next yr from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm depending on species. Dwarf types such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might develop as extra tall as 80 cm.
The crops are scapose, having a single central leafless hollow flower stem (scape). Several blue-green or green, narrow, strap-shaped leaves arise from the light. The place stem bears a solitary flower, but sometimes a cluster of blossoms (umbel). The blossoms, that happen to be conspicuous and white or yellowish usually, both or rarely renewable sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outer ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical molded corona. The blooms may hang down (pendent), or be erect. You will discover six pollen bearing stamens encircling a central style. The ovary is second-rate (below the floral parts) consisting of three chambers (trilocular). The fruit involves a dried out capsule that splits (dehisces) launching numerous black seed products.
The bulb lays dormant following the leaves and flower stem die back and has contractile roots that pull it down further into the soil. The blossom leaves and stem form in the bulb, to emerge the next season. Most species are dormant from summer time to late winter, flowering in the planting season, though a few kinds are fall months flowering.
