Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial crops 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 the cup- or trumpet-shaped corona. The plants are generally white or yellow (orange or green in garden varieties), with either standard or contrasting coloured tepals and corona.
Narcissus were popular in early civilisation, both medicinally and botanically, but formally referred to by Linnaeus in his Types Plantarum (1753). The genus is normally considered to have about ten sections with about 50 species. The amount of species has assorted, depending about how they are grouped, anticipated to similarity between types and hybridization. The genus arose some right amount of time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise source of the real name Narcissus is undiscovered, but it is often associated with a Greek word for intoxicated (narcotic) and the misconception of the youngsters of that name who fell in love with his own reflection. The English term 'daffodil' appears to be derived from "asphodel", with which it was commonly compared.
The kinds are local to meadows and woods in southern European countries and North Africa with a center of variety in the American Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were introduced into the Far East prior to the tenth century. 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, nematodes and mites. Some Narcissus species have grown to be extinct, while some are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe after the 16th century and by the later 19th hundred years were an important commercial crop centred mostly on holland. Narcissi are popular as slash blooms and since ornamental plants in private and public gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering a wide range of shapes and colours. Like other members with their family, narcissi create a number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested unintentionally. This property has been exploited for medicinal utilization in traditional healing and has led to 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 various cultures, ranging from fatality to good fortune, and as icons of spring and coil. The daffodil is the countrywide rose of Wales and the sign of cancer tumor charities in many countries. The appearance of the outdoors flowers in spring is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to an underground storage bulb. They regrow in the next 12 months from brown-skinned ovoid bulbs with pronounced necks, and reach levels of 5-80 cm with regards to the species. Dwarf types such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may develop as high as 80 cm.
The vegetation are scapose, having a single central leafless hollow blossom stem (scape). Several blue-green or green, narrow, strap-shaped leaves come up from the light bulb. The place stem usually bears a solitary flower, but sometimes a cluster of blossoms (umbel). The plants, that happen to be usually conspicuous and white or yellowish, both or almost never inexperienced sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an exterior ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical formed corona. The flowers may hang down (pendent), or be erect. You can find six pollen bearing stamens encircling a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The berries consists of a dried up capsule that splits (dehisces) releasing numerous black seeds.
The bulb is placed dormant following the leaves and flower stem die back again and has contractile roots that take it down further into the soil. The rose stem and leaves form in the bulb, to emerge the following season. Most species are dormant from summertime to later winter, flowering in the spring and coil, though a few types are fall flowering.
