Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common names 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 bouquets are generally white or yellow (orange or red in garden kinds), with either standard or contrasting coloured corona and tepals.
Narcissus were well known in early civilisation, both and botanically medicinally, but formally described by Linnaeus in his Kinds Plantarum (1753). The genus is normally considered to have about ten sections with about 50 species. The true number of kinds has mixed, depending about how they are categorised, anticipated to similarity between kinds and hybridization. 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 exact source of the real name Narcissus is undiscovered, but it is linked to a Greek term for intoxicated (narcotic) and the myth of the young ones of this name who fell in love with his own reflection. The English expression 'daffodil' is apparently derived from "asphodel", with which it was likened commonly.
The kinds are indigenous to meadows and woods in southern European countries and North Africa with a middle of variety in the Western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were created in to the ASIA to the tenth hundred years prior. Narcissi have a tendency 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 become extinct, while others 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 century and by the overdue 19th hundred years were an important commercial crop centred primarily on holland. Narcissi are popular as trim bouquets and as ornamental plants in private and general population gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering an array of shapes and colours. Like other members of their family, narcissi produce a true 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 treating Alzheimer's dementia. Long celebrated in literature and art work, narcissi are associated with a number of themes in various cultures, ranging from fatality to fortune, and as symbols of spring and coil. The daffodil is the countrywide flower of Wales and the image of cancers charities in many countries. The looks of the outdoors flowers in spring is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to an underground storage bulb. They regrow in the next 12 months from brown-skinned ovoid lights with pronounced necks, and reach levels 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 might grow as large as 80 cm.
The plant life are scapose, having an individual central leafless hollow bloom stem (scape). Several blue-green or green, narrow, strap-shaped leaves occur from the bulb. The plant stem usually bears a solitary rose, but occasionally a cluster of bouquets (umbel). The blossoms, which can be usually conspicuous and white or yellow, both or hardly ever inexperienced sometimes, 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 blooms may hang up down (pendent), or be erect. There are six pollen bearing stamens adjoining a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The fruit consists of a dried capsule that splits (dehisces) launching numerous black seeds.
The bulb is situated dormant after the leaves and blossom stem die back and has contractile origins that yank it down further into the soil. The blossom leaves and stem form in the light, to emerge the next season. Most varieties are dormant from summertime to later winter, flowering in the spring and coil, though a few types are fall flowering.
