Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common labels including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are being 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 plants are generally white or yellow (orange or red in garden types), with either even or contrasting coloured corona and tepals.
Narcissus were well known in early civilisation, both and botanically medicinally, but formally referred to by Linnaeus in his Types Plantarum (1753). The genus is generally considered to have about ten areas with around 50 species. The true amount of species has mixed, depending about how they are categorized, thanks to similarity between hybridization and types. The genus arose some time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact origins of the name Narcissus is unidentified, but it is often linked to a Greek phrase for intoxicated (narcotic) and the misconception of the young ones of that name who fell in love with his own reflection. The English phrase 'daffodil' is apparently produced from "asphodel", with which it was compared commonly.
The kinds are indigenous to meadows and woods in southern European countries and North Africa with a centre of diversity in the European Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were created into the ASIA to the tenth century 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, nematodes and mites. Some Narcissus species have grown to be extinct, while some are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe following the 16th century and by the overdue 19th hundred years were an important commercial crop centred primarily on the Netherlands. Today narcissi are popular as slash blooms and since ornamental plants in private and open public gardens. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a variety of colours and shapes. Like other members of the family, narcissi produce a true number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested unintentionally. 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 work, narcissi are associated with a number of themes in different cultures, ranging from loss of life to good fortune, and as icons of planting season. The daffodil is the nationwide rose of Wales and the icon of tumor charities in many countries. The appearance of the outrageous flowers in spring and coil is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering for an underground storage light. They regrow in the next 12 months from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm with respect to the species. Dwarf kinds such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might increase as large as 80 cm.
The plant life are scapose, having an individual central leafless hollow blossom stem (scape). Several blue-green or green, narrow, strap-shaped leaves arise from the light. The herb stem usually bears a solitary bloom, but occasionally a cluster of plants (umbel). The blossoms, that happen to be usually conspicuous and white or yellowish, both or rarely renewable sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outer ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical shaped corona. The blooms may hang down (pendent), or be erect. You can find six pollen bearing stamens bordering a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The fruit involves a dried capsule that splits (dehisces) liberating numerous black seeds.
The bulb is dormant after the leaves and flower stem die again and has contractile root base that yank it down further into the soil. The bloom leaves and stem form in the light, to emerge the next season. Most species are dormant from summer time to later winter, flowering in the planting season, though a few kinds are fall flowering.
