Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common names 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 the cup- or trumpet-shaped corona. The blooms are usually white or yellow (orange or pink in garden kinds), with either uniform or contrasting coloured corona and tepals.
Narcissus were well known in historic civilisation, both and botanically medicinally, but formally identified by Linnaeus in his Types Plantarum (1753). The genus is normally considered to have about ten parts with around 50 species. The amount of species has varied, depending how they are categorised, credited to similarity between types and hybridization. The genus arose some time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise source of the name Narcissus is mysterious, but it is often associated with a Greek word for intoxicated (narcotic) and the myth of the young ones of this name who fell in love with his own representation. The English term 'daffodil' is apparently derived from "asphodel", with which it was commonly likened.
The types are native to meadows and woods in southern European countries and North Africa with a centre of variety in the American Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were unveiled into the Far East to the tenth hundred years prior. Narcissi have a tendency 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, 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 initial times, but became increasingly popular in Europe after the 16th hundred years and by the past due 19th century were an important commercial crop centred primarily on holland. Narcissi are popular as chop bouquets and as ornamental plants in private and general public gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering a wide range of colours and shapes. Like other members of the 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 used in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in artwork and books, 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 countrywide rose of Wales and the sign of cancer charities in many countries. The looks of the crazy flowers in springtime is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to the underground storage light. They regrow in the following season from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf species such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might increase as large as 80 cm.
The vegetation are scapose, having a single central leafless hollow bloom stem (scape). Several blue-green or green, slim, strap-shaped leaves happen from the light. The seed stem bears a solitary rose, but occasionally a cluster of blooms (umbel). The blossoms, that are conspicuous and white or yellow usually, both or hardly ever inexperienced sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an external ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The blossoms may hang up down (pendent), or be erect. There are six pollen bearing stamens bordering a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The fruits involves a dried out capsule that splits (dehisces) releasing numerous black seeds.
The bulb is placed dormant following the leaves and flower stem die again and has contractile roots that yank it down further into the soil. The flower leaves and stem form in the light, to emerge the next season. Most kinds are dormant from summer months to later winter, flowering in the springtime, though a few species are autumn flowering.
