Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plant life 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 blossoms are generally white or yellow (orange or pink in garden types), with either standard or contrasting colored corona and tepals.
Narcissus were well known in old civilisation, both medicinally and botanically, but formally described by Linnaeus in his Species Plantarum (1753). The genus is generally considered to have about ten areas with roughly 50 species. The true amount of types has varied, depending about how they are categorised, thanks to similarity between hybridization and varieties. The genus arose some right 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 unidentified, but it is linked to a Greek expression for intoxicated (narcotic) and the myth of the youth of that name who fell deeply in love with his own representation. The English phrase 'daffodil' appears to be produced 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 middle of diversity in the European Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were released into the Far East to the tenth hundred years prior. Narcissi tend to be long-lived bulbs, which propagate by division, but are also insect-pollinated. Known pests, diseases and disorders include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have grown to be 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 later 19th hundred years were an important commercial crop centred primarily on the Netherlands. Narcissi are popular as chop blossoms so that as ornamental crops in private and public gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a variety of colours and shapes. Like other members of these family, narcissi produce 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 resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in art work and books, narcissi are associated with a number of themes in different cultures, ranging from loss of life to good fortune, and as symbols of spring and coil. The daffodil is the nationwide blossom of Wales and the image of cancers charities in many countries. The looks of the wild flowers in planting season is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering to a underground storage light bulb. They regrow in the following calendar year from brown-skinned ovoid bulbs with pronounced necks, and reach levels of 5-80 cm with respect to the species. Dwarf varieties such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may increase as high as 80 cm.
The plants are scapose, having a single central leafless hollow blossom stem (scape). Several blue-green or green, small, strap-shaped leaves come up from the bulb. The plant stem bears a solitary bloom, but occasionally a cluster of flowers (umbel). The plants, which are conspicuous and white or yellow usually, both or almost never renewable sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outer ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical designed corona. The flowers may hang down (pendent), or be erect. You will discover six pollen bearing stamens encompassing a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The fruit contains a dry capsule that splits (dehisces) liberating numerous black seeds.
The bulb lays dormant after the leaves and blossom stem die back and has contractile origins that yank it down further in to the soil. The rose leaves and stem form in the light, to emerge the following season. Most kinds are dormant from summer time to past due winter, flowering in the spring, though a few species are fall flowering.
