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 being 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 blooms are generally white or yellow (orange or pink in garden kinds), with either uniform or contrasting coloured tepals and corona.
Narcissus were popular in traditional civilisation, both and botanically medicinally, but formally detailed by Linnaeus in his Kinds Plantarum (1753). The genus is generally considered to have about ten areas with about 50 species. The true range of varieties has varied, depending on how they are classified, due to similarity between hybridization and types. 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 exact origin of the real name Narcissus is anonymous, but it is associated with a Greek term for intoxicated (narcotic) and the myth of the children of that name who fell in love with his own reflection. The English word 'daffodil' appears to be produced from "asphodel", with which it was likened commonly.
The species are indigenous to meadows and woods in southern Europe and North Africa with a centre of variety in the American Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were presented into the Far East to the tenth hundred years prior. 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 urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe after the 16th century and by the late 19th hundred years were an important commercial crop centred primarily on holland. Today narcissi are popular as cut plants and since ornamental plant life in private and general population gardens. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering an array of colours and shapes. Like other members of these family, narcissi create 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 treating Alzheimer's dementia. Long celebrated in books and fine art, narcissi are associated with a number of themes in several cultures, ranging from loss of life to fortune, and as symbols of springtime. The daffodil is the national rose of Wales and the symbol of cancer tumor charities in many countries. The looks of the wild flowers in springtime 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 light. They regrow in the next season from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm with regards to the species. Dwarf varieties such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may grow as extra tall as 80 cm.
The plant life are scapose, having a single central leafless hollow rose stem (scape). Several blue-green or green, slim, strap-shaped leaves come up from the bulb. The herb stem usually bears a solitary rose, but occasionally a cluster of bouquets (umbel). The bouquets, that happen to be conspicuous and white or yellowish usually, sometimes both or rarely green, 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 disc to conical shaped corona. The blooms may suspend down (pendent), or be erect. You can find six pollen bearing stamens adjoining a central style. The ovary is second-rate (below the floral parts) consisting of three chambers (trilocular). The berries includes a dried up capsule that splits (dehisces) liberating numerous black seed products.
The bulb lies dormant following the leaves and blossom stem die again and has contractile roots that pull it down further into the soil. The flower stem and leaves form in the light bulb, to emerge the next season. Most types are dormant from summer season to overdue winter, flowering in the springtime, though a few varieties are fall flowering.
