Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common labels 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 way of a cup- or trumpet-shaped corona. The bouquets are usually white or yellowish (orange or pink in garden varieties), with either uniform or contrasting colored tepals and corona.
Narcissus were well known in historic civilisation, both and botanically medicinally, but formally detailed by Linnaeus in his Kinds Plantarum (1753). The genus is generally considered to have about ten portions with approximately 50 species. The true variety of species has mixed, depending how they are classified, thanks to similarity between hybridization and species. The genus arose some right time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise source of the real name Narcissus is undiscovered, but it is often associated with a Greek phrase for intoxicated (narcotic) and the myth of the children of that name who fell deeply in love with his own reflection. The English expression 'daffodil' is apparently derived from "asphodel", with which it was likened commonly.
The species are local to meadows and woods in southern Europe and North Africa with a centre of variety in the Western Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were unveiled into the ASIA to the tenth hundred years prior. 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, nematodes and mites. Some Narcissus species have grown to be extinct, while some are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the initial times, but became ever more popular in Europe following the 16th hundred years and by the later 19th century were an important commercial crop centred primarily on holland. Today narcissi are popular as trim plants and as ornamental plant life in private and general public gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering an array of colours and shapes. Like other members of these family, narcissi produce a true 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 used in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in skill and books, narcissi are associated with a true number of themes in different cultures, ranging from loss of life to good fortune, and as symbols of spring and coil. The daffodil is the national flower of Wales and the mark of malignancy charities in many countries. The looks of the wild flowers in spring is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering with an underground storage light. They regrow in the following year from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm depending on the species. Dwarf species such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may increase as large as 80 cm.
The plants are scapose, having an individual central leafless hollow bloom stem (scape). Several green or blue-green, narrow, strap-shaped leaves happen from the light bulb. The vegetable stem usually bears a solitary flower, but once in a while a cluster of blooms (umbel). The flowers, that happen to be usually conspicuous and white or yellowish, sometimes both or seldom renewable, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outer ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical shaped corona. The blooms may hang down (pendent), or be erect. You will find six pollen bearing stamens surrounding a central style. The ovary is substandard (below the floral parts) consisting of three chambers (trilocular). The berries includes a dry out capsule that splits (dehisces) liberating numerous black seed products.
The bulb is dormant following the leaves and flower stem die back and has contractile origins that draw it down further into the soil. The bloom leaves and stem form in the light bulb, to emerge the next season. Most species are dormant from summer season to late winter, flowering in the spring, though a few kinds are fall months flowering.
