Narcissus /n?:r's?s?s/ is a genus of predominantly 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 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 usually white or yellow (orange or pink in garden kinds), with either even or contrasting colored corona and tepals.
Narcissus were well known in traditional civilisation, both medicinally and botanically, but formally described by Linnaeus in his Species Plantarum (1753). The genus is normally thought to have about ten portions with about 50 species. The number of kinds has mixed, depending how they are grouped, credited to similarity between species and hybridization. The genus arose some 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 anonymous, but it is often associated with a Greek phrase for intoxicated (narcotic) and the misconception of the children of that name who fell in love with his own reflection. The English expression 'daffodil' is apparently derived from "asphodel", with which it was commonly compared.
The varieties are local to meadows and woods in southern European countries and North Africa with a centre of variety in the European Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were introduced in to the Far East before the tenth century. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are also insect-pollinated. Known pests, diseases and disorders include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have become extinct, while others are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the initial times, but became ever more popular in Europe after the 16th century and by the overdue 19th century were an important commercial crop centred mainly on holland. Narcissi are popular as slash blooms and as ornamental vegetation in private and general public gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering an array of colours and shapes. Like other members of the family, narcissi create a true 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 resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in fine art and literature, narcissi are associated with a number of themes in different cultures, ranging from fatality to good fortune, and as icons of spring. The daffodil is the nationwide rose of Wales and the icon of cancer charities in many countries. The looks of the outdoors flowers in springtime is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to the underground storage light. They regrow in the next yr from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm with respect to the species. Dwarf species such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might grow as high as 80 cm.
The crops are scapose, having a single central leafless hollow rose stem (scape). Several blue-green or green, small, strap-shaped leaves happen from the light. The plant stem usually bears a solitary bloom, but occasionally a cluster of flowers (umbel). The flowers, which can be conspicuous and white or yellow usually, sometimes both or hardly ever green, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outside 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. You will find six pollen bearing stamens bordering a central style. The ovary is inferior (below the floral parts) consisting of three chambers (trilocular). The super fruit involves a dried out capsule that splits (dehisces) liberating numerous black seed products.
The bulb sits dormant following the leaves and blossom stem die back again and has contractile root base that take it down further into the soil. The rose leaves and stem form in the light bulb, to emerge the next season. Most species are dormant from summer season to later winter, flowering in the spring, though a few kinds are fall flowering.
