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 used to describe all or some members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by a cup- or trumpet-shaped corona. The blossoms are generally white or yellow (orange or red in garden varieties), with either even or contrasting coloured tepals and corona.
Narcissus were well known in historic civilisation, both medicinally and botanically, but formally explained by Linnaeus in his Species Plantarum (1753). The genus is normally considered to have about ten parts with about 50 species. The amount of varieties has assorted, depending how they are grouped, due 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 areas of southwest Europe. The precise source of the name Narcissus is unidentified, but it is often linked to a Greek expression for intoxicated (narcotic) and the misconception of the young ones of this name who fell in love with his own representation. The English phrase 'daffodil' is apparently produced from "asphodel", with which it was likened commonly.
The species are indigenous to meadows and woods in southern Europe and North Africa with a centre of variety in the Traditional western Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were introduced into the Far East to the tenth hundred years prior. Narcissi tend 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 grown to be extinct, while others are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe following the 16th century and by the later 19th hundred years were an important commercial crop centred mostly on the Netherlands. Today narcissi are popular as trim bouquets so that ornamental plant life in private and public gardens. The long history of breeding has led to 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 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 in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in books and skill, narcissi are associated with a number of themes in several cultures, ranging from death to fortune, and as icons of springtime. The daffodil is the nationwide flower of Wales and the symbol of malignancy charities in many countries. The appearance 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 the underground storage light bulb. They regrow in the next yr from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm depending on the species. Dwarf types such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may grow as tall as 80 cm.
The plants are scapose, having a single central leafless hollow blossom stem (scape). Several green or blue-green, narrow, strap-shaped leaves arise from the light bulb. The herb stem bears a solitary rose, but once in a while a cluster of blooms (umbel). The plants, which can be conspicuous and white or yellow usually, both or rarely renewable sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outer ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical designed corona. The bouquets may hang 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 fruit contains a dried out capsule that splits (dehisces) launching numerous black seeds.
The bulb is situated dormant following the leaves and blossom stem die back again and has contractile root base that move it down further into the soil. The blossom stem and leaves form in the bulb, to emerge the following season. Most species are dormant from summer season to later winter, flowering in the spring and coil, though a few kinds are fall flowering.
