Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common brands including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are 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 blossoms are usually white or yellow (orange or green in garden kinds), with either uniform or contrasting colored corona and tepals.
Narcissus were well known in early civilisation, both and botanically medicinally, but formally detailed by Linnaeus in his Types Plantarum (1753). The genus is generally thought to have about ten sections with roughly 50 species. The true amount of species has varied, depending how they are grouped, due to similarity between species and hybridization. The genus arose some right time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The exact origins of the name Narcissus is unidentified, but it is often associated with a Greek term for intoxicated (narcotic) and the misconception of the junior of that 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 varieties are indigenous to meadows and woods in southern Europe and North Africa with a center of variety in the Traditional western Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were introduced in to the Far East prior to 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, nematodes and mites. Some Narcissus species have become extinct, while others are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe after the 16th century and by the overdue 19th hundred years were an important commercial crop centred primarily on the Netherlands. Today narcissi are popular as lower blooms and since ornamental vegetation in private and general public gardens. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering a variety of shapes and colours. Like other members with their family, narcissi create a number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested accidentally. This property has been exploited for medicinal used in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in books and art work, narcissi are associated with a number of themes in several cultures, ranging from death to good fortune, and as icons of springtime. The daffodil is the nationwide blossom of Wales and the image of tumor charities in many countries. The appearance of the untamed 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 the underground storage light bulb. They regrow in the next season from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm with respect to the species. Dwarf types such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may develop as tall as 80 cm.
The plant life are scapose, having a single central leafless hollow rose stem (scape). Several blue-green or green, slim, strap-shaped leaves occur from the light bulb. The seed stem bears a solitary rose, but once in a while a cluster of bouquets (umbel). The blooms, which are usually conspicuous and white or yellow, both or rarely green 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 shaped corona. The blossoms may hang up down (pendent), or be erect. There are six pollen bearing stamens adjoining a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The berry contains a dry out capsule that splits (dehisces) launching numerous black seeds.
The bulb lays dormant after the leaves and blossom stem die back again and has contractile roots that draw it down further in to the soil. The bloom stem and leaves form in the bulb, to emerge the following season. Most types are dormant from summer season to later winter, flowering in the spring and coil, though a few species are autumn flowering.
