Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common names including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are being used to describe all or some known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted with a cup- or trumpet-shaped corona. The bouquets are usually white or yellowish (orange or pink in garden types), with either uniform or contrasting colored corona and tepals.
Narcissus were well known in early civilisation, both and botanically medicinally, but formally defined by Linnaeus in his Kinds Plantarum (1753). The genus is normally considered to have about ten areas with about 50 species. The true range of varieties has mixed, depending how they are categorised, anticipated to similarity between kinds and hybridization. The genus arose time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The exact source of the true name Narcissus is unidentified, 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 reflection. The English expression 'daffodil' is apparently produced from "asphodel", with which it was likened commonly.
The types are native to meadows and woods in southern European countries and North Africa with a middle of variety in the Traditional western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were unveiled 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, disorders and diseases include viruses, fungi, the larvae of flies, nematodes and mites. 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 following the 16th hundred years and by the past due 19th century were an important commercial crop centred mostly on holland. Narcissi are popular as slash plants as ornamental crops 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 ingested unintentionally. This property has been exploited for medicinal use in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in books and artwork, narcissi are associated with a number of themes in several cultures, ranging from fatality to good fortune, and as symbols of planting season. The daffodil is the national bloom of Wales and the image of cancer tumor charities in many countries. The looks of the outdoors flowers in springtime is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering for an underground storage light bulb. They regrow in the following year from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm depending on species. Dwarf kinds such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may develop as large as 80 cm.
The vegetation are scapose, having an individual central leafless hollow bloom stem (scape). Several blue-green or green, slim, strap-shaped leaves come up from the light bulb. The seed stem usually bears a solitary flower, but occasionally a cluster of plants (umbel). The flowers, that are conspicuous and white or yellow usually, sometimes both or rarely inexperienced, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an external ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical molded corona. The flowers 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 contains a dried out 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 pull it down further in to the soil. The rose stem and leaves form in the light bulb, to emerge the following season. Most types are dormant from summer months to past due winter, flowering in the planting season, though a few kinds are fall months flowering.
