Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common titles 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 way of a cup- or trumpet-shaped corona. The bouquets are usually white or yellowish (orange or pink in garden varieties), with either standard or contrasting colored tepals and corona.
Narcissus were popular in old civilisation, both and botanically medicinally, but formally identified by Linnaeus in his Types Plantarum (1753). The genus is generally thought to have about ten areas with approximately 50 species. The number of types has mixed, depending how they are grouped, due to similarity between hybridization and species. The genus arose some time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise source of the true name Narcissus is unidentified, but it is often associated with a Greek word for intoxicated (narcotic) and the myth of the youngsters of that name who fell in love with his own reflection. The English expression 'daffodil' appears to be derived from "asphodel", with which it was likened commonly.
The varieties are indigenous to meadows and woods in southern European countries and North Africa with a centre of variety in the Western 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 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, nematodes and mites. Some Narcissus species have become extinct, while some are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe following the 16th century and by the past due 19th hundred years were an important commercial crop centred mainly on holland. Today narcissi are popular as trim flowers so that as ornamental vegetation in private and general public gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering an array of shapes and colours. Like other members with their 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 utilization in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in skill and books, narcissi are associated with a number of themes in various cultures, ranging from fatality to good fortune, and as symbols of spring. The daffodil is the countrywide flower of Wales and the icon of malignancy 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 to an underground storage light. 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 level of 5-8 cm, while Narcissus tazetta may increase as high as 80 cm.
The plants are scapose, having an individual central leafless hollow bloom stem (scape). Several blue-green or green, narrow, strap-shaped leaves arise from the bulb. The herb stem usually bears a solitary flower, but occasionally a cluster of plants (umbel). The blooms, that are conspicuous and white or yellow usually, sometimes both or almost never green, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outside ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical shaped corona. The flowers may hang up down (pendent), or be erect. You will discover six pollen bearing stamens adjoining a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The berries consists of a dried capsule that splits (dehisces) liberating 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 into the soil. The flower leaves and stem form in the light, to emerge the following season. Most types are dormant from summertime to late winter, flowering in the planting season, though a few kinds are fall months flowering.
