Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common brands including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are used to describe all or some members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by way of a cup- or trumpet-shaped corona. The blooms are generally white or yellowish (orange or green in garden kinds), with either standard or contrasting coloured tepals and corona.
Narcissus were popular in historical civilisation, both medicinally and botanically, but formally explained by Linnaeus in his Kinds Plantarum (1753). The genus is normally thought to have about ten areas with approximately 50 species. The number of kinds has varied, depending how they are classified, due to similarity between hybridization and kinds. 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 source of the name Narcissus is anonymous, but it is linked to a Greek term for intoxicated (narcotic) and the myth of the young ones of that name who fell in love with his own representation. The English phrase 'daffodil' is apparently produced from "asphodel", with which it was commonly compared.
The types are indigenous to meadows and woods in southern Europe and North Africa with a centre of diversity in the American Mediterranean, particularly the Iberian peninsula. 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, diseases and disorders 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 hundred years and by the overdue 19th hundred years were an important commercial crop centred primarily on holland. Narcissi are popular as trim blossoms and as ornamental vegetation in private and general public gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering a wide range 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 use within traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in art work and literature, narcissi are associated with a number of themes in different cultures, ranging from death to good fortune, and as icons of springtime. The daffodil is the countrywide flower of Wales and the mark of tumors charities in many countries. The appearance of the untamed flowers in springtime is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering for an underground storage light bulb. They regrow in the next time from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf varieties such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may expand as large as 80 cm.
The plants are scapose, having an individual central leafless hollow bloom stem (scape). Several blue-green or green, small, strap-shaped leaves happen from the light. The place stem usually bears a solitary blossom, but occasionally a cluster of blooms (umbel). The plants, that are usually conspicuous and white or yellowish, both or seldom green 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 disc to conical formed corona. The blossoms may hang down (pendent), or be erect. You will discover six pollen bearing stamens adjoining a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The berries contains a dry capsule that splits (dehisces) releasing numerous black seeds.
The bulb lies dormant following the leaves and rose stem die back again and has contractile root base that draw it down further in to the soil. The rose leaves and stem form in the bulb, to emerge the next season. Most varieties are dormant from summertime to overdue winter, flowering in the planting season, though a few varieties are autumn flowering.
