Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial crops 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 by the cup- or trumpet-shaped corona. The plants are generally white or yellowish (orange or green in garden types), with either uniform or contrasting colored tepals and corona.
Narcissus were popular in traditional civilisation, both and botanically medicinally, but formally described by Linnaeus in his Types Plantarum (1753). The genus is normally considered to have about ten areas with approximately 50 species. The true quantity of kinds has mixed, depending about how they are grouped, scheduled to similarity between species and hybridization. The genus arose some right time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The exact origin of the name Narcissus is unfamiliar, but it is associated with a Greek word for intoxicated (narcotic) and the misconception of the young ones of that name who fell deeply in love with his own representation. The English term 'daffodil' is apparently produced from "asphodel", with which it was compared commonly.
The species are native to meadows and woods in southern Europe and North Africa with a centre of variety in the European 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, 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 initial times, but became ever more popular in Europe following the 16th century and by the overdue 19th century were an important commercial crop centred generally on holland. Narcissi are popular as slash plants so when ornamental plants in private and general public gardens today. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a wide range of shapes and colours. Like other members of these family, narcissi produce a true number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested accidentally. This property has been exploited for medicinal use within traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in art work and books, narcissi are associated with a number of themes in various cultures, ranging from fatality to good fortune, and as symbols of springtime. The daffodil is the national blossom of Wales and the icon of cancer tumor charities in many countries. The appearance of the outrageous flowers in planting season is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering with an underground storage light bulb. They regrow in the next time from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm depending on the species. Dwarf varieties such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may develop as high as 80 cm.
The plant life are scapose, having a single central leafless hollow flower stem (scape). Several green or blue-green, slim, strap-shaped leaves come up from the light bulb. The vegetable stem bears a solitary rose, but occasionally a cluster of blossoms (umbel). The bouquets, which can be conspicuous and white or yellow usually, sometimes both or seldom renewable, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an external ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The plants may hang up down (pendent), or be erect. You can find six pollen bearing stamens adjoining a central style. The ovary is second-rate (below the floral parts) consisting of three chambers (trilocular). The berries contains a dried up capsule that splits (dehisces) releasing numerous black seed products.
The bulb lays dormant after the leaves and rose stem die again and has contractile roots that yank it down further into the soil. The rose leaves and stem form in the light bulb, to emerge the next season. Most types are dormant from warmer summer months to later winter, flowering in the spring and coil, though a few varieties are autumn flowering.
