Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common titles 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 with a cup- or trumpet-shaped corona. The flowers are usually white or yellow (orange or pink in garden types), with either uniform or contrasting colored tepals and corona.
Narcissus were popular in ancient civilisation, both and botanically medicinally, but formally defined by Linnaeus in his Varieties Plantarum (1753). The genus is generally thought to have about ten sections with roughly 50 species. The number of kinds has mixed, depending how they are grouped, a consequence of to similarity between hybridization and types. 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 source of the name Narcissus is unknown, but it is associated with a Greek phrase for intoxicated (narcotic) and the myth of the youngsters 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 commonly compared.
The varieties are indigenous to meadows and woods in southern Europe and North Africa with a middle of variety in the Western Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were launched in to the ASIA to the tenth century prior. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are insect-pollinated also. Known pests, disorders and diseases 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 after the 16th century and by the late 19th century were an important commercial crop centred generally on the Netherlands. Narcissi are popular as lower blooms so that ornamental crops in private and public gardens today. The long history of breeding has led to 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 these 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 used in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in literature and art, narcissi are associated with a true number of themes in several cultures, ranging from fatality to fortune, and as icons of spring and coil. The daffodil is the countrywide bloom of Wales and the icon of cancer tumor charities in many countries. The looks of the crazy flowers in spring and coil is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering with an underground storage light bulb. They regrow in the next calendar year from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf types such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might develop as large as 80 cm.
The vegetation are scapose, having a single central leafless hollow rose stem (scape). Several blue-green or green, slim, strap-shaped leaves happen from the light. The plant stem usually bears a solitary flower, but occasionally a cluster of blooms (umbel). The plants, which are usually conspicuous and white or yellowish, both or seldom renewable sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an exterior ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical designed corona. The blossoms may hang down (pendent), or be erect. You will discover six pollen bearing stamens adjoining a central style. The ovary is inferior (below the floral parts) consisting of three chambers (trilocular). The berry includes a dried up capsule that splits (dehisces) liberating numerous black seed products.
The bulb is dormant following the leaves and blossom stem die again and has contractile roots that move it down further in to the soil. The rose leaves and stem form in the bulb, to emerge the following season. Most kinds are dormant from summer months to overdue winter, flowering in the planting season, though a few species are fall flowering.
