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 a cup- or trumpet-shaped corona. The blossoms are usually white or yellow (orange or pink in garden types), with either standard or contrasting coloured corona and tepals.
Narcissus were popular in historical civilisation, both and botanically medicinally, but formally identified by Linnaeus in his Types Plantarum (1753). The genus is generally considered to have about ten parts with roughly 50 species. The true volume of varieties has assorted, depending about how they are labeled, thanks to similarity between hybridization and varieties. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact source of the real name Narcissus is unknown, but it is associated with a Greek term for intoxicated (narcotic) and the misconception of the children of that name who fell in love with his own representation. The English term 'daffodil' is apparently produced from "asphodel", with which it was commonly likened.
The varieties are native to meadows and woods in southern European countries and North Africa with a centre of diversity in the Traditional western Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were unveiled in to the ASIA to the tenth hundred years prior. 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 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 hundred years and by the late 19th century were an important commercial crop centred mostly on holland. Today narcissi are popular as cut blooms so when ornamental vegetation 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 categorized into divisions, covering an array 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 use in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in literature and fine art, narcissi are associated with a number of themes in different cultures, ranging from death to good fortune, and as symbols of spring. The daffodil is the national blossom of Wales and the image of tumor charities in many countries. The looks of the untamed 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 a underground storage bulb. They regrow in the next 12 months from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf kinds such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may grow as extra tall as 80 cm.
The crops are scapose, having a single central leafless hollow bloom stem (scape). Several green or blue-green, thin, strap-shaped leaves occur from the light bulb. The place stem usually bears a solitary bloom, but occasionally a cluster of plants (umbel). The plants, that happen to be conspicuous and white or yellow usually, both or rarely inexperienced sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an exterior ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical molded corona. The plants may hang up down (pendent), or be erect. A couple of six pollen bearing stamens encircling a central style. The ovary is substandard (below the floral parts) consisting of three chambers (trilocular). The fruits includes a dried up capsule that splits (dehisces) launching numerous black seeds.
The bulb is placed dormant following the leaves and flower stem die back again and has contractile origins that move it down further into the soil. The blossom leaves and stem form in the light bulb, to emerge the next season. Most species are dormant from summer months to later winter, flowering in the springtime, though a few types are fall months flowering.
