Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common brands 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 way of a cup- or trumpet-shaped corona. The bouquets are generally white or yellowish (orange or pink in garden varieties), with either uniform or contrasting colored corona and tepals.
Narcissus were well known in traditional civilisation, both and botanically medicinally, but formally defined by Linnaeus in his Varieties Plantarum (1753). The genus is normally thought to have about ten portions with around 50 species. The true volume of types has varied, depending how they are grouped, credited to similarity between varieties and hybridization. The genus arose some right amount of time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise source of the real name Narcissus is unidentified, but it is linked to a Greek phrase for intoxicated (narcotic) and the myth of the youngsters of that name who fell deeply in love with his own representation. The English word 'daffodil' appears to be produced from "asphodel", with which it was likened commonly.
The kinds are local to meadows and woods in southern Europe and North Africa with a middle of diversity in the American Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were introduced into the Far East prior to the tenth century. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are also insect-pollinated. Known pests, disorders and diseases include viruses, fungi, the larvae of flies, nematodes and mites. Some Narcissus species have grown to be extinct, while others are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the initial times, but became ever more popular in Europe following the 16th century and by the late 19th century were an important commercial crop centred mainly on holland. Today narcissi are popular as lower blossoms and since ornamental plants in private and general population gardens. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a variety of shapes and colours. Like other members with their family, narcissi produce a true 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 used in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in artwork and books, narcissi are associated with a true number of themes in several cultures, ranging from death to good fortune, and as icons of planting season. The daffodil is the countrywide flower of Wales and the symbol of cancer tumor charities in many countries. The looks of the untamed flowers in springtime is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to a underground storage light. They regrow in the following yr from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm depending on species. Dwarf varieties such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may increase as large as 80 cm.
The plants are scapose, having a single central leafless hollow flower stem (scape). Several blue-green or green, slim, strap-shaped leaves arise from the bulb. The place stem usually bears a solitary flower, but once in a while a cluster of bouquets (umbel). The plants, which are usually conspicuous and white or yellowish, both or almost never renewable sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an exterior ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical designed corona. The plants may hang up down (pendent), or be erect. A couple of six pollen bearing stamens encompassing a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The super fruit includes a dried up capsule that splits (dehisces) releasing numerous black seeds.
The bulb is placed dormant after the leaves and blossom stem die back and has contractile origins that draw it down further in to the soil. The bloom leaves and stem form in the bulb, to emerge the next season. Most kinds are dormant from summer season to overdue winter, flowering in the spring, though a few species are autumn flowering.
