Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plants 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 way of a cup- or trumpet-shaped corona. The bouquets are usually white or yellowish (orange or green in garden varieties), with either even or contrasting coloured tepals and corona.
Narcissus were popular in historic civilisation, both and botanically medicinally, but formally referred to by Linnaeus in his Varieties Plantarum (1753). The genus is normally thought to have about ten portions with approximately 50 species. The true range of varieties has assorted, depending how they are categorised, due to similarity between hybridization and kinds. 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 origins of the true name Narcissus is mysterious, but it is often associated with a Greek term for intoxicated (narcotic) and the myth of the youngsters of this name who fell in love with his own reflection. The English expression 'daffodil' appears to be derived from "asphodel", with which it was likened commonly.
The types are local to meadows and woods in southern European countries and North Africa with a center of variety in the Traditional western Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were introduced into the Far East before the tenth century. 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 tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe following the 16th hundred years and by the past due 19th hundred years were an important commercial crop centred mostly on holland. Narcissi are popular as lower bouquets as ornamental vegetation in private and general public gardens today. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering an array of colours and shapes. Like other members with their family, narcissi create a 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 used in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in art work and literature, narcissi are associated with a true number of themes in several cultures, ranging from loss of life to good fortune, and as icons of spring. The daffodil is the nationwide rose of Wales and the symbol of cancers charities in many countries. The appearance of the crazy flowers in springtime is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering to the underground storage light bulb. They regrow in the following 12 months from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm depending on the species. Dwarf kinds such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might grow as tall as 80 cm.
The plant life are scapose, having a single central leafless hollow flower stem (scape). Several blue-green or green, narrow, strap-shaped leaves occur from the bulb. The plant stem bears a solitary flower, but occasionally a cluster of bouquets (umbel). The blossoms, that happen to be 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 pipe above the ovary, then an outside ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical shaped corona. The blooms may hang up down (pendent), or be erect. There are six pollen bearing stamens surrounding a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The berry includes a dried up capsule that splits (dehisces) releasing numerous black seeds.
The bulb lies dormant following the leaves and flower stem die back again and has contractile roots that draw it down further in to the soil. The rose leaves and stem form in the light, to emerge the next season. Most varieties are dormant from summer time to late winter, flowering in the spring and coil, though a few types are fall flowering.
