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 being used to describe all or some known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by way of a cup- or trumpet-shaped corona. The plants are generally white or yellowish (orange or red in garden kinds), with either uniform or contrasting colored corona and tepals.
Narcissus were well known in early civilisation, both and botanically medicinally, but formally referred to by Linnaeus in his Varieties Plantarum (1753). The genus is generally thought to have about ten sections with around 50 species. The true amount of kinds has varied, depending on how they are classified, scheduled to similarity between types and hybridization. The genus arose 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 anonymous, but it is linked to a Greek expression for intoxicated (narcotic) and the misconception of the junior of this 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 varieties are indigenous to meadows and woods in southern Europe and North Africa with a middle of diversity in the American 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 have a tendency 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, mites and nematodes. Some Narcissus species have grown to be 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 after the 16th hundred years and by the later 19th century were an important commercial crop centred primarily on the Netherlands. Today narcissi are popular as lower flowers as ornamental crops in private and open public gardens. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a variety of colours and shapes. 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 accidentally ingested. This property has been exploited for medicinal used in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in art work and books, narcissi are associated with a true number of themes in several cultures, ranging from loss of life to good fortune, and as symbols of springtime. The daffodil is the countrywide bloom of Wales and the image of cancer tumor charities in many countries. The appearance of the outrageous flowers in spring is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to a underground storage light. They regrow in the following 12 months 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 height of 5-8 cm, while Narcissus tazetta may grow as tall as 80 cm.
The vegetation are scapose, having a single central leafless hollow bloom stem (scape). Several blue-green or green, thin, strap-shaped leaves come up from the light bulb. The flower stem usually bears a solitary flower, but sometimes a cluster of blooms (umbel). The plants, that happen to be conspicuous and white or yellowish usually, sometimes both or hardly ever renewable, consist of 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 disk to conical formed corona. The bouquets may hang down (pendent), or be erect. A couple of six pollen bearing stamens encircling a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The berries includes a dried up capsule that splits (dehisces) releasing numerous black seeds.
The bulb is placed dormant after the leaves and rose stem die back again and has contractile root base that pull 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 months to later winter, flowering in the planting season, though a few varieties are autumn flowering.
