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 being used to describe all or some members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by way of a cup- or trumpet-shaped corona. The flowers are usually white or yellowish (orange or green in garden kinds), with either even or contrasting colored tepals and corona.
Narcissus were popular in old civilisation, both medicinally and botanically, but formally defined by Linnaeus in his Types Plantarum (1753). The genus is generally considered to have about ten portions with around 50 species. The amount of species has mixed, depending how they are labeled, anticipated to similarity between varieties 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 precise origins of the name Narcissus is mysterious, but it is linked to a Greek expression for intoxicated (narcotic) and the misconception of the youth of that name who fell deeply in love with his own reflection. The English term 'daffodil' is apparently derived from "asphodel", with which it was compared commonly.
The varieties are indigenous to meadows and woods in southern Europe and North Africa with a middle of variety in the European Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were introduced into the Far East before 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, mites and nematodes. Some Narcissus species have become extinct, while some are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe after the 16th century and by the overdue 19th hundred years were an important commercial crop centred mostly on holland. Narcissi are popular as lower bouquets so when ornamental plant life in private and open public gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering a variety of colours and shapes. Like other members of the family, narcissi produce a number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested accidentally. This property has been exploited for medicinal use in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in fine art and books, narcissi are associated with a true number of themes in various cultures, ranging from loss of life to fortune, and as icons of spring. The daffodil is the countrywide rose of Wales and the symbol of tumor charities in many countries. The appearance of the outdoors flowers in spring is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering with an underground storage light. They regrow in the next season 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 elevation of 5-8 cm, while Narcissus tazetta may increase as tall as 80 cm.
The vegetation are scapose, having a single central leafless hollow rose stem (scape). Several blue-green or green, slim, strap-shaped leaves happen from the light. The herb stem usually bears a solitary bloom, but once in a while a cluster of blossoms (umbel). The flowers, that happen to be conspicuous and white or yellow usually, sometimes both or rarely renewable, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outside ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical molded corona. The flowers may hang down (pendent), or be erect. You will discover six pollen bearing stamens adjoining a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The fruits consists of a dried up capsule that splits (dehisces) liberating numerous black seed products.
The bulb lies dormant following the leaves and blossom stem die again and has contractile origins that take it down further into the soil. The bloom leaves and stem form in the light bulb, to emerge the following season. Most species are dormant from summer months to past due winter, flowering in the spring, though a few species are fall flowering.
