Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common brands 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 by a cup- or trumpet-shaped corona. The blossoms are usually white or yellowish (orange or pink in garden types), with either even or contrasting colored corona and tepals.
Narcissus were well known in early civilisation, both medicinally and botanically, but formally detailed by Linnaeus in his Species Plantarum (1753). The genus is generally considered to have about ten portions with roughly 50 species. The true amount of kinds has mixed, depending how they are classified, due to similarity between hybridization and kinds. The genus arose some time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact origins of the name Narcissus is unknown, but it is often associated with a Greek word for intoxicated (narcotic) and the myth of the junior of that name who fell in love with his own reflection. The English word 'daffodil' is apparently produced from "asphodel", with which it was likened commonly.
The kinds are indigenous 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 cultivated and wild plants have naturalised widely, and were introduced in to the Far East prior to the tenth century. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are insect-pollinated also. 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 urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe after the 16th hundred years and by the late 19th hundred years were an important commercial crop centred primarily on holland. Today narcissi are popular as cut blooms so that as ornamental crops in private and public gardens. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a variety of shapes and colours. Like other members of these 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 utilization in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in fine art and literature, narcissi are associated with a number of themes in several cultures, ranging from fatality to good fortune, and as symbols of springtime. The daffodil is the countrywide bloom of Wales and the sign of tumors charities in many countries. The appearance of the wild flowers in planting season is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to an underground storage bulb. They regrow in the next year from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm depending on species. Dwarf kinds such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might grow as extra tall as 80 cm.
The vegetation are scapose, having a single central leafless hollow blossom stem (scape). Several blue-green or green, thin, strap-shaped leaves happen from the light bulb. The herb stem bears a solitary rose, but sometimes a cluster of blossoms (umbel). The flowers, that are usually conspicuous and white or yellowish, both or almost never green sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an external ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical molded corona. The bouquets may hang up down (pendent), or be erect. There are six pollen bearing stamens encompassing a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The fruits contains a dried out capsule that splits (dehisces) releasing numerous black seeds.
The bulb is dormant after the leaves and rose stem die back and has contractile root base that move it down further into the soil. The blossom leaves and stem form in the light, to emerge the following season. Most types are dormant from warmer summer months to past due winter, flowering in the spring, though a few types are fall months flowering.
