Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common brands 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 way of a cup- or trumpet-shaped corona. The blooms are usually white or yellowish (orange or green in garden kinds), with either even or contrasting colored corona and tepals.
Narcissus were well known in historic civilisation, both and botanically medicinally, but formally identified by Linnaeus in his Species Plantarum (1753). The genus is generally thought to have about ten parts with roughly 50 species. The true variety of types has mixed, depending about how they are classified, thanks to similarity between hybridization and varieties. The genus arose some right time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The exact source of the real name Narcissus is undiscovered, but it is often associated with a Greek phrase for intoxicated (narcotic) and the myth of the junior of this name who fell in love with his own reflection. The English expression '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 middle of variety in the American Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were unveiled in to the ASIA to the tenth hundred years prior. Narcissi tend to be long-lived bulbs, which propagate by division, but are also insect-pollinated. Known pests, diseases and disorders include viruses, fungi, the larvae of flies, nematodes and mites. 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 hundred years and by the late 19th century were an important commercial crop centred generally on the Netherlands. Today narcissi are popular as chop bouquets and since ornamental vegetation in private and general population gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering a wide range of colours and shapes. Like other members of these family, narcissi produce a 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 use in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in literature and artwork, narcissi are associated with a number of themes in several cultures, ranging from loss of life to good fortune, and as icons of springtime. The daffodil is the nationwide flower of Wales and the icon of cancer charities in many countries. The looks of the outrageous 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 a underground storage light bulb. They regrow in the following year 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 bloom stem (scape). Several green or blue-green, slim, strap-shaped leaves arise from the light. The seed stem usually bears a solitary bloom, but occasionally a cluster of flowers (umbel). The bouquets, which are usually conspicuous and white or yellow, both or seldom inexperienced sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outside ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical molded corona. The blossoms may suspend down (pendent), or be erect. There are six pollen bearing stamens adjoining a central style. The ovary is second-rate (below the floral parts) consisting of three chambers (trilocular). The super fruit involves a dried capsule that splits (dehisces) launching numerous black seed products.
The bulb lays dormant after the leaves and flower stem die back and has contractile origins that yank it down further in to the soil. The blossom stem and leaves form in the light bulb, to emerge the following season. Most species are dormant from summer to late winter, flowering in the spring and coil, though a few types are fall flowering.
