Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common labels including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are 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 varieties), with either even or contrasting colored corona and tepals.
Narcissus were well known in historical civilisation, both medicinally and botanically, but formally detailed by Linnaeus in his Varieties Plantarum (1753). The genus is generally considered to have about ten portions with about 50 species. The number of types has mixed, depending about how they are grouped, a consequence of to similarity between hybridization and kinds. 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 anonymous, but it is often associated with a Greek word for intoxicated (narcotic) and the myth of the children of that name who fell in love with his own reflection. The English phrase 'daffodil' is apparently produced from "asphodel", with which it was compared commonly.
The kinds are native to meadows and woods in southern Europe and North Africa with a center of variety in the Traditional western Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were launched 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, diseases and disorders 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 ever more popular in Europe following the 16th hundred years and by the later 19th century were an important commercial crop centred generally on holland. Narcissi are popular as trim flowers so when ornamental plants in private and general population gardens today. The long history of breeding has led to 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 the family, narcissi produce a 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 utilization in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in literature and art work, narcissi are associated with a 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 sign of cancer tumor charities in many countries. The looks of the outdoors flowers in spring and coil is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering with an underground storage bulb. They regrow in the next calendar year from brown-skinned ovoid bulbs with pronounced necks, and reach levels of 5-80 cm depending on the species. Dwarf types such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might expand as extra tall as 80 cm.
The plant life are scapose, having a single central leafless hollow rose stem (scape). Several green or blue-green, thin, strap-shaped leaves occur from the light bulb. The flower stem usually bears a solitary rose, but once in a while a cluster of plants (umbel). The blossoms, that happen to be conspicuous and white or yellowish usually, both or seldom renewable sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an external ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical designed corona. The plants may hang up down (pendent), or be erect. There are six pollen bearing stamens adjoining a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The berries contains a dry out capsule that splits (dehisces) releasing numerous black seed products.
The bulb is dormant after the leaves and blossom stem die again and has contractile root base that pull it down further in to the soil. The bloom stem and leaves form in the light, to emerge the next season. Most kinds are dormant from summer months to past due winter, flowering in the spring, though a few varieties are fall months flowering.
