Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common labels 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 the cup- or trumpet-shaped corona. The blossoms are usually white or yellowish (orange or green in garden varieties), with either even or contrasting colored tepals and corona.
Narcissus were popular in historic civilisation, both medicinally and botanically, but formally detailed by Linnaeus in his Species Plantarum (1753). The genus is normally considered to have about ten sections with approximately 50 species. The true amount of types has mixed, depending on how they are categorised, as a consequence to similarity between hybridization and kinds. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact origin of the real name Narcissus is unidentified, but it is associated with a Greek word for intoxicated (narcotic) and the misconception of the youth of that name who fell in love with his own reflection. The English word 'daffodil' is apparently produced from "asphodel", with which it was commonly likened.
The kinds are indigenous to meadows and woods in southern European countries and North Africa with a center of variety in the European Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were unveiled into the ASIA to the tenth century prior. Narcissi tend to be long-lived bulbs, which propagate by division, but are insect-pollinated also. Known pests, diseases and disorders include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have grown to be extinct, while some are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became ever more popular in Europe after the 16th hundred years and by the past due 19th century were an important commercial crop centred generally on holland. Narcissi are popular as cut flowers so that as ornamental crops in private and open public gardens today. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering a wide range of shapes and colours. 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 ingested inadvertently. This property has been exploited for medicinal use in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in fine art and literature, narcissi are associated with a number of themes in several cultures, ranging from loss of life to good fortune, and as icons of planting season. The daffodil is the countrywide rose of Wales and the image of malignancy charities in many countries. The looks of the outrageous flowers in spring and coil is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering to an underground storage light bulb. They regrow in the following season from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm depending on the species. Dwarf kinds such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might develop as large as 80 cm.
The vegetation are scapose, having an individual central leafless hollow bloom stem (scape). Several green or blue-green, narrow, strap-shaped leaves come up from the light. The plant stem usually bears a solitary rose, but occasionally a cluster of blooms (umbel). The blooms, which can be conspicuous and white or yellow usually, sometimes both or almost never renewable, contain 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 disk to conical shaped corona. The flowers may suspend down (pendent), or be erect. You will find six pollen bearing stamens encircling a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The fruits consists of a dried capsule that splits (dehisces) releasing numerous black seeds.
The bulb lays dormant following the leaves and flower stem die back again and has contractile root base that draw it down further into the soil. The blossom stem and leaves form in the light bulb, to emerge the following season. Most kinds are dormant from summer time to later winter, flowering in the spring, though a few varieties are fall months flowering.
