Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common titles 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 blooms are generally white or yellowish (orange or red in garden types), with either even or contrasting colored corona and tepals.
Narcissus were popular in traditional civilisation, both medicinally and botanically, but formally referred to by Linnaeus in his Types Plantarum (1753). The genus is normally thought to have about ten sections with roughly 50 species. The true volume of kinds has assorted, depending on how they are labeled, due to similarity between hybridization and species. 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 origin of the true name Narcissus is undiscovered, but it is often linked to a Greek word for intoxicated (narcotic) and the myth of the youngsters of this name who fell in love with his own reflection. The English phrase 'daffodil' appears to be produced from "asphodel", with which it was likened commonly.
The varieties are native to meadows and woods in southern Europe and North Africa with a center of variety in the American Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were introduced into 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, 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 increasingly popular in Europe following the 16th century and by the late 19th century were an important commercial crop centred mainly on the Netherlands. Narcissi are popular as slash blossoms and as ornamental plants in private and public gardens today. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering an array of shapes and colours. Like other members of these 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 in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in art and literature, narcissi are associated with a true number of themes in several cultures, ranging from loss of life to fortune, and as icons of planting season. The daffodil is the countrywide flower of Wales and the icon of malignancy charities in many countries. The looks of the crazy flowers in spring and coil is associated with festivals 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 bulbs with pronounced necks, and reach levels of 5-80 cm with respect to the species. Dwarf species such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may increase as tall as 80 cm.
The vegetation are scapose, having a single central leafless hollow flower stem (scape). Several blue-green or green, small, strap-shaped leaves occur from the bulb. The seed stem bears a solitary flower, but occasionally a cluster of flowers (umbel). The plants, which are conspicuous and white or yellow usually, both or seldom green sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outer ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical molded corona. The plants may hang down (pendent), or be erect. You can find six pollen bearing stamens adjoining a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The berries includes a dried out capsule that splits (dehisces) launching numerous black seed products.
The bulb lies dormant following the leaves and bloom stem die again and has contractile origins that move it down further in to the soil. The rose leaves and stem form in the light bulb, to emerge the following season. Most varieties are dormant from summer months to past due winter, flowering in the planting season, though a few types are autumn flowering.
