Narcissus /n?:r's?s?s/ is a genus of predominantly 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 way of a cup- or trumpet-shaped corona. The blossoms are usually white or yellowish (orange or pink in garden kinds), with either standard or contrasting coloured corona and tepals.
Narcissus were popular in traditional civilisation, both and botanically medicinally, but formally identified by Linnaeus in his Species Plantarum (1753). The genus is generally considered to have about ten portions with around 50 species. The number of kinds has assorted, depending about how they are categorized, due to similarity between kinds and hybridization. The genus arose some right amount of 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 mysterious, but it is often linked to a Greek phrase for intoxicated (narcotic) and the misconception of the children of this name who fell in love with his own reflection. The English expression 'daffodil' appears to be produced from "asphodel", with which it was compared commonly.
The species are local to meadows and woods in southern Europe and North Africa with a middle of variety in the Western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were created in to the Far East to the tenth century prior. Narcissi tend 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 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 hundred years and by the overdue 19th century were an important commercial crop centred mainly on the Netherlands. Narcissi are popular as chop plants so when 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 categorised into divisions, covering a variety of shapes and colours. Like other members of the family, narcissi create 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 use in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in books and art work, narcissi are associated with a true number of themes in several cultures, ranging from death to fortune, and as icons of springtime. The daffodil is the countrywide rose of Wales and the symbol of cancer tumor charities in many countries. The looks of the wild flowers in planting season 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 season from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm depending on species. Dwarf kinds such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may develop as tall as 80 cm.
The crops are scapose, having a single central leafless hollow bloom stem (scape). Several blue-green or green, thin, strap-shaped leaves occur from the light. The herb stem usually bears a solitary flower, but once in a while a cluster of blossoms (umbel). The bouquets, which are conspicuous and white or yellow usually, both or rarely inexperienced sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outside ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The plants may hang down (pendent), or be erect. You can find six pollen bearing stamens surrounding a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The berries contains a dried up capsule that splits (dehisces) liberating numerous black seeds.
The bulb lays dormant following the leaves and flower stem die back again and has contractile roots that pull it down further into the soil. The flower stem and leaves form in the bulb, to emerge the following season. Most kinds are dormant from summer season to overdue winter, flowering in the spring and coil, though a few kinds are fall flowering.
