Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common brands 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 a cup- or trumpet-shaped corona. The plants are usually white or yellow (orange or pink in garden varieties), with either even or contrasting colored tepals and corona.
Narcissus were popular in old civilisation, both and botanically medicinally, but formally identified by Linnaeus in his Kinds Plantarum (1753). The genus is generally considered to have about ten areas with about 50 species. The true variety of varieties has varied, depending on how they are categorized, credited to similarity between varieties and hybridization. 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 exact origins of the name Narcissus is unfamiliar, but it is often linked to a Greek word for intoxicated (narcotic) and the myth of the young ones of this name who fell in love with his own representation. The English expression 'daffodil' appears to be derived from "asphodel", with which it was likened commonly.
The kinds are native to meadows and woods in southern European countries and North Africa with a middle of variety in the American Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were introduced in to the Far East before 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, mites and nematodes. Some Narcissus species have become extinct, while others are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe after the 16th hundred years and by the later 19th century were an important commercial crop centred mostly on holland. Today narcissi are popular as chop blossoms and since ornamental plants in private and open public gardens. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering an array of colours and shapes. Like other members with their family, narcissi create a true 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 use in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in books and fine art, narcissi are associated with a true number of themes in different cultures, ranging from loss of life to good fortune, and as icons of spring and coil. The daffodil is the countrywide rose of Wales and the mark of tumors charities in many countries. The looks of the crazy flowers in planting season 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 light. They regrow in the following yr from brown-skinned ovoid bulbs with pronounced necks, and reach levels of 5-80 cm with regards to the species. Dwarf kinds such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may develop as high as 80 cm.
The plant life are scapose, having a single central leafless hollow rose stem (scape). Several blue-green or green, small, strap-shaped leaves come up from the bulb. The plant stem usually bears a solitary blossom, but occasionally a cluster of bouquets (umbel). The blossoms, which are conspicuous and white or yellowish usually, both or almost never renewable sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an exterior ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical designed corona. The bouquets may suspend down (pendent), or be erect. You can find six pollen bearing stamens encircling a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The fruit consists of a dried capsule that splits (dehisces) launching numerous black seed products.
The bulb lays dormant following the leaves and blossom stem die back and has contractile origins that take it down further in to the soil. The rose stem and leaves form in the bulb, to emerge the next season. Most varieties are dormant from warmer summer months to late winter, flowering in the springtime, though a few species are fall flowering.
