Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common labels including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are used to describe all or some known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by way of a cup- or trumpet-shaped corona. The plants are usually white or yellowish (orange or pink in garden types), with either uniform or contrasting coloured tepals and corona.
Narcissus were popular in historic civilisation, both medicinally and botanically, but formally detailed by Linnaeus in his Species Plantarum (1753). The genus is generally thought to have about ten sections with roughly 50 species. The true range of types has varied, depending how they are labeled, as a consequence 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 precise origins of the name Narcissus is undiscovered, but it is often linked to a Greek phrase for intoxicated (narcotic) and the misconception of the youth of this name who fell in love with his own representation. The English word 'daffodil' appears to be derived from "asphodel", with which it was commonly compared.
The species are indigenous to meadows and woods in southern European countries and North Africa with a center of variety in the European Mediterranean, particularly the Iberian peninsula. 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 also insect-pollinated. Known pests, disorders and diseases include viruses, fungi, the larvae of flies, nematodes and mites. Some Narcissus species have become extinct, while some 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 century and by the overdue 19th hundred years were an important commercial crop centred mainly on the Netherlands. Narcissi are popular as slice flowers and as ornamental crops in private and general population gardens today. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a wide range 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 led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in literature and art, narcissi are associated with a number of themes in different cultures, ranging from loss of life to good fortune, and as symbols of planting season. The daffodil is the national bloom of Wales and the symbol of cancer tumor 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 bulb. They regrow in the next 12 months from brown-skinned ovoid bulbs with pronounced necks, and reach levels of 5-80 cm with regards to the species. Dwarf species such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may grow as high as 80 cm.
The plants are scapose, having a single central leafless hollow blossom stem (scape). Several green or blue-green, thin, strap-shaped leaves occur from the light. The flower stem usually bears a solitary flower, but sometimes a cluster of bouquets (umbel). The blooms, that are conspicuous and white or yellowish usually, sometimes both or rarely renewable, 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 disk to conical formed corona. The plants may suspend down (pendent), or be erect. You can find 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 capsule that splits (dehisces) liberating numerous black seed products.
The bulb is dormant following the leaves and flower stem die back and has contractile origins that yank it down further in to the soil. The bloom stem and leaves form in the bulb, to emerge the next season. Most types are dormant from warmer summer months to overdue winter, flowering in the spring, though a few kinds are autumn flowering.
