Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common titles 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 a cup- or trumpet-shaped corona. The bouquets are usually white or yellow (orange or pink in garden varieties), with either standard or contrasting coloured corona and tepals.
Narcissus were popular in traditional civilisation, both medicinally and botanically, but formally identified by Linnaeus in his Kinds Plantarum (1753). The genus is normally considered to have about ten sections with around 50 species. The number of species has mixed, depending on how they are categorized, due to similarity between hybridization and species. 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 origins of the true name Narcissus is unknown, but it is often linked to a Greek term for intoxicated (narcotic) and the myth of the junior of this name who fell in love with his own representation. The English term 'daffodil' appears to be produced from "asphodel", with which it was compared commonly.
The species are indigenous to meadows and woods in southern Europe and North Africa with a center of variety in the Western Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were presented into the Far East to the tenth century prior. 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 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 hundred years were an important commercial crop centred mostly on holland. Today narcissi are popular as slice bouquets so when ornamental plants in private and general public gardens. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering a wide range of colours and shapes. Like other members of these family, narcissi create a true number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested accidentally. This property has been exploited for medicinal use in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in art work and books, narcissi are associated with a true number of themes in several cultures, ranging from death to fortune, and as icons of spring and coil. The daffodil is the countrywide bloom of Wales and the sign of tumor charities in many countries. The looks of the outrageous flowers in planting season 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 calendar year from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm depending on the species. Dwarf varieties such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may expand as large as 80 cm.
The crops are scapose, having an individual central leafless hollow flower stem (scape). Several green or blue-green, slim, strap-shaped leaves come up from the light bulb. The seed stem usually bears a solitary rose, but once in a while a cluster of flowers (umbel). The bouquets, that are conspicuous and white or yellowish usually, both or rarely green sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an exterior 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. You will find six pollen bearing stamens encircling a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The berries involves a dried capsule that splits (dehisces) liberating numerous black seeds.
The bulb lies dormant following the leaves and flower stem die back again and has contractile origins that take it down further into the soil. The bloom leaves and stem form in the light bulb, to emerge the next season. Most types are dormant from warmer summer months to late winter, flowering in the spring, though a few kinds are fall flowering.
