Narcissus /n?:r's?s?s/ is a genus of predominantly 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 with a cup- or trumpet-shaped corona. The bouquets are generally white or yellow (orange or pink in garden types), with either standard or contrasting coloured corona and tepals.
Narcissus were well known in historic civilisation, both medicinally and botanically, but formally explained by Linnaeus in his Kinds Plantarum (1753). The genus is generally considered to have about ten sections with about 50 species. The true volume of species has mixed, depending how they are classified, due 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 areas of southwest Europe. The exact origins of the name Narcissus is undiscovered, but it is often linked to a Greek word for intoxicated (narcotic) and the myth of the youth of this name who fell in love with his own reflection. The English word 'daffodil' is apparently derived from "asphodel", with which it was commonly likened.
The varieties are local to meadows and woods in southern European countries and North Africa with a center of diversity in the European Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were introduced in to the Far East prior to the tenth century. Narcissi tend 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 grown to be extinct, while some are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became ever more popular in Europe following the 16th hundred years and by the late 19th century were an important commercial crop centred generally on holland. Narcissi are popular as chop blooms so that as ornamental vegetation in private and general population gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering an array of colours and shapes. Like other members of their family, narcissi create 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 used in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in literature and art work, narcissi are associated with a number of themes in different cultures, ranging from loss of life to good fortune, and as icons of spring. The daffodil is the nationwide blossom of Wales and the mark of malignancy charities in many countries. The appearance of the untamed flowers in spring is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering to the underground storage bulb. They regrow in the next time from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm with respect to the species. Dwarf species such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may expand as high as 80 cm.
The plant life are scapose, having a single central leafless hollow bloom stem (scape). Several blue-green or green, slim, strap-shaped leaves occur from the bulb. The seed stem bears a solitary flower, but occasionally a cluster of bouquets (umbel). The blossoms, that are usually conspicuous and white or yellow, both or hardly ever 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 disc to conical molded corona. The blooms may hang up down (pendent), or be erect. A couple of six pollen bearing stamens encompassing a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The fruit includes a dry out capsule that splits (dehisces) liberating numerous black seeds.
The bulb lies dormant after the leaves and flower stem die again and has contractile root base that yank it down further into the soil. The blossom leaves and stem form in the light, to emerge the following season. Most kinds are dormant from summer season to past due winter, flowering in the spring and coil, though a few species are autumn flowering.
