Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common names 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 bouquets are generally white or yellow (orange or pink in garden types), with either uniform or contrasting coloured tepals and corona.
Narcissus were popular in traditional civilisation, both and botanically medicinally, but formally referred to by Linnaeus in his Varieties Plantarum (1753). The genus is normally considered to have about ten areas with roughly 50 species. The amount of species has assorted, depending on how they are categorised, anticipated to similarity between kinds 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 exact origins of the true name Narcissus is unfamiliar, but it is associated with a Greek phrase for intoxicated (narcotic) and the misconception of the young ones of this name who fell in love with his own representation. The English term 'daffodil' is apparently derived from "asphodel", with which it was compared commonly.
The types are local to meadows and woods in southern Europe and North Africa with a center of diversity in the Traditional western Mediterranean, the Iberian peninsula particularly. 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, disorders and diseases include viruses, fungi, the larvae of flies, mites and nematodes. 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 ever more popular in Europe after the 16th century and by the later 19th hundred years were an important commercial crop centred generally on the Netherlands. Today narcissi are popular as trim flowers and as ornamental plants in private and public gardens. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering a wide range of colours and shapes. Like other members of these family, narcissi produce 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 within traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in artwork and literature, narcissi are associated with a number of themes in several cultures, ranging from fatality to fortune, and as symbols of planting season. The daffodil is the national bloom of Wales and the image of cancer charities in many countries. The appearance of the outdoors flowers in spring 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 bulb. They regrow in the next year from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf types such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might develop as tall as 80 cm.
The vegetation are scapose, having an individual central leafless hollow rose stem (scape). Several blue-green or green, thin, strap-shaped leaves arise from the light bulb. The flower stem bears a solitary bloom, but occasionally a cluster of blossoms (umbel). The blooms, which can be usually conspicuous and white or yellow, 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 disc to conical shaped corona. The blossoms may hang up down (pendent), or be erect. You will find six pollen bearing stamens adjoining a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The fruits involves a dried out capsule that splits (dehisces) launching numerous black seeds.
The bulb sits dormant after the leaves and blossom stem die back and has contractile roots that move it down further in to the soil. The bloom leaves and stem form in the light bulb, to emerge the following season. Most varieties are dormant from summer time to later winter, flowering in the spring, though a few types are autumn flowering.
