Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plants 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 the cup- or trumpet-shaped corona. The blossoms are generally white or yellowish (orange or pink in garden kinds), with either standard or contrasting coloured tepals and corona.
Narcissus were well known in historical civilisation, both and botanically medicinally, but formally identified by Linnaeus in his Varieties Plantarum (1753). The genus is normally considered to have about ten areas with roughly 50 species. The true volume of varieties has mixed, depending about how they are classified, due 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 origin of the name Narcissus is unknown, but it is associated with a Greek phrase for intoxicated (narcotic) and the misconception of the junior of this name who fell in love with his own reflection. The English phrase 'daffodil' is apparently produced from "asphodel", with which it was commonly likened.
The kinds are native to meadows and woods in southern Europe and North Africa with a middle of diversity in the Western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were introduced in to 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, disorders and diseases include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have become extinct, while some are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became ever more popular in Europe following the 16th century and by the overdue 19th hundred years were an important commercial crop centred generally on holland. Narcissi are popular as slice blossoms so when ornamental crops in private and open public gardens today. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering a wide range of colours and shapes. Like other members of their family, narcissi create a 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 utilization in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in literature and fine art, narcissi are associated with a true number of themes in various cultures, ranging from loss of life to good fortune, and as symbols of spring. The daffodil is the national blossom of Wales and the image of cancers charities in many countries. The looks of the outdoors 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 to a underground storage light. They regrow in the next year from brown-skinned ovoid light bulbs with pronounced necks, and reach levels 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 develop as extra tall as 80 cm.
The crops are scapose, having a single central leafless hollow blossom stem (scape). Several green or blue-green, slim, strap-shaped leaves arise from the bulb. The seed stem bears a solitary rose, but occasionally a cluster of flowers (umbel). The flowers, that happen to be conspicuous and white or yellowish usually, both or hardly ever 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 disk to conical molded corona. The blooms may hang up down (pendent), or be erect. A couple of six pollen bearing stamens encompassing a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The fruits includes a dry out capsule that splits (dehisces) releasing numerous black seed products.
The bulb is situated dormant following the leaves and flower stem die back and has contractile root base that yank it down further into the soil. The flower leaves and stem form in the light bulb, to emerge the next season. Most kinds are dormant from summer months to later winter, flowering in the spring, though a few kinds are fall months flowering.
