Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common titles 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 plants are usually white or yellow (orange or pink in garden varieties), with either even or contrasting colored corona and tepals.
Narcissus were popular in historic civilisation, both and botanically medicinally, but formally referred to by Linnaeus in his Types Plantarum (1753). The genus is normally considered to have about ten areas with roughly 50 species. The number of types has varied, depending how they are categorised, due to similarity between hybridization and varieties. 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 unidentified, but it is often linked to a Greek expression for intoxicated (narcotic) and the myth of the young ones of that name who fell deeply in love with his own representation. The English expression 'daffodil' is apparently derived from "asphodel", with which it was compared commonly.
The species are local to meadows and woods in southern Europe and North Africa with a center of diversity in the European Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were unveiled in to the ASIA to the tenth century 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 tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe after the 16th hundred years and by the overdue 19th century were an important commercial crop centred mainly on the Netherlands. Narcissi are popular as slice blooms so that as ornamental plant life in private and open public gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering a variety of shapes and colours. Like other members of their family, narcissi create a true number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested inadvertently. This property has been exploited for medicinal used in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in artwork and literature, narcissi are associated with a true number of themes in different cultures, ranging from death to fortune, and as symbols of spring and coil. The daffodil is the nationwide rose of Wales and the sign of cancer charities in many countries. The appearance of the outrageous flowers in spring is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering with an underground storage light bulb. They regrow in the following calendar year from brown-skinned ovoid bulbs with pronounced necks, and reach levels of 5-80 cm depending on the species. Dwarf species such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might grow as extra tall as 80 cm.
The plants are scapose, having a single central leafless hollow rose stem (scape). Several blue-green or green, small, strap-shaped leaves arise from the bulb. The herb stem bears a solitary flower, but sometimes a cluster of plants (umbel). The blooms, that happen to be usually conspicuous and white or yellowish, both or hardly ever green sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outside ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical shaped corona. The blooms may suspend down (pendent), or be erect. You will discover six pollen bearing stamens encircling a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The fruits includes a dry capsule that splits (dehisces) releasing numerous black seeds.
The bulb lies dormant following the leaves and rose stem die back and has contractile roots that take it down further in to the soil. The bloom leaves and stem form in the light, to emerge the next season. Most types are dormant from summer season to late winter, flowering in the planting season, though a few varieties are fall flowering.
