Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common names 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 the cup- or trumpet-shaped corona. The blossoms are generally white or yellowish (orange or red in garden varieties), with either uniform or contrasting coloured tepals and corona.
Narcissus were well known in traditional civilisation, both and botanically medicinally, but formally detailed by Linnaeus in his Species Plantarum (1753). The genus is normally considered to have about ten areas with approximately 50 species. The true range of species has assorted, depending on how they are categorized, due to similarity between hybridization and types. The genus arose some right amount of 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 unfamiliar, but it is linked to a Greek word for intoxicated (narcotic) and the misconception of the junior of that name who fell in love with his own reflection. The English expression 'daffodil' is apparently produced from "asphodel", with which it was compared commonly.
The types are native to meadows and woods in southern Europe and North Africa with a middle of diversity in the Western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were introduced in to the Far East prior to 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 become extinct, while others 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 following the 16th hundred years and by the late 19th century were an important commercial crop centred mainly on the Netherlands. Today narcissi are popular as slash bouquets as ornamental plants in private and general population gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering an array of shapes and colours. Like other members of their family, narcissi produce 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 utilization in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in books and fine art, narcissi are associated with a number of themes in several cultures, ranging from fatality to fortune, and as icons of spring and coil. The daffodil is the nationwide rose of Wales and the image of cancer tumor charities in many countries. The appearance of the outrageous 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 to a underground storage light. They regrow in the next 12 months from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm depending on the species. Dwarf varieties such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might develop as extra tall as 80 cm.
The vegetation are scapose, having an individual central leafless hollow flower stem (scape). Several blue-green or green, thin, strap-shaped leaves come up from the light. The place stem usually bears a solitary blossom, but occasionally a cluster of plants (umbel). The blossoms, that are conspicuous and white or yellowish usually, sometimes both or seldom renewable, 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 disc to conical designed corona. The flowers may suspend down (pendent), or be erect. You will find six pollen bearing stamens surrounding a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The fruits includes a dried capsule that splits (dehisces) liberating numerous black seeds.
The bulb lays dormant after the leaves and blossom stem die back and has contractile root base that yank it down further into the soil. The bloom leaves and stem form in the bulb, to emerge the next season. Most varieties are dormant from summertime to past due winter, flowering in the planting season, though a few types are fall months flowering.
