Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common brands 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 a cup- or trumpet-shaped corona. The blooms are usually white or yellowish (orange or red in garden types), with either standard or contrasting coloured tepals and corona.
Narcissus were popular in historic civilisation, both medicinally and botanically, but formally defined by Linnaeus in his Kinds Plantarum (1753). The genus is generally thought to have about ten sections with approximately 50 species. The amount of varieties has varied, depending about how they are categorized, a consequence of to similarity between hybridization and kinds. The genus arose some 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 unidentified, but it is associated with a Greek expression for intoxicated (narcotic) and the misconception of the youth of this name who fell deeply in love with his own representation. The English term 'daffodil' is apparently produced from "asphodel", with which it was commonly compared.
The kinds are local to meadows and woods in southern Europe 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 into 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, diseases and disorders 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 initial times, but became ever more popular in Europe following the 16th hundred years and by the later 19th century were an important commercial crop centred primarily on the Netherlands. Narcissi are popular as cut bouquets as ornamental crops in private and general public gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a wide range of shapes and colours. Like other members of the 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 use within traditional healing and has resulted in 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 various cultures, ranging from loss of life to fortune, and as symbols of planting season. The daffodil is the national blossom of Wales and the sign of malignancy charities in many countries. The looks of the crazy flowers in spring and coil is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering with an underground storage light bulb. They regrow in the next time from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm depending on species. Dwarf species such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may increase as extra tall as 80 cm.
The plants are scapose, having an individual central leafless hollow rose stem (scape). Several blue-green or green, slim, strap-shaped leaves arise from the light. The flower stem bears a solitary blossom, but once in a while a cluster of bouquets (umbel). The plants, that are conspicuous and white or yellow usually, both or rarely inexperienced sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an external ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical designed corona. The blossoms may suspend down (pendent), or be erect. You can find six pollen bearing stamens adjoining a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The berry consists of a dry out capsule that splits (dehisces) liberating numerous black seed products.
The bulb is placed dormant following the leaves and blossom stem die back and has contractile origins that move it down further into the soil. The blossom leaves and stem form in the light, to emerge the following season. Most types are dormant from summer season to past due winter, flowering in the planting season, though a few types are autumn flowering.
