Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common titles 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 with a cup- or trumpet-shaped corona. The flowers 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 medicinally and botanically, but formally detailed by Linnaeus in his Kinds Plantarum (1753). The genus is normally thought to have about ten sections with about 50 species. The true variety of kinds has varied, depending on how they are categorized, anticipated to similarity between types 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 real name Narcissus is unidentified, but it is often linked to a Greek term for intoxicated (narcotic) and the myth of the youth of that name who fell in love with his own reflection. The English word 'daffodil' appears to be derived from "asphodel", with which it was commonly compared.
The kinds are native to meadows and woods in southern Europe and North Africa with a middle of variety in the American Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were introduced into the ASIA to the tenth century prior. 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 tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe following the 16th hundred years and by the overdue 19th century were an important commercial crop centred mostly on holland. Today narcissi are popular as chop flowers so that ornamental plants in private and general public gardens. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a variety of colours and shapes. Like other members of the family, narcissi produce a 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 used in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in literature and art work, narcissi are associated with a number of themes in several cultures, ranging from death to good fortune, and as icons of spring. The daffodil is the national rose of Wales and the mark of tumor charities in many countries. The appearance of the crazy flowers in planting season is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to the underground storage bulb. They regrow in the next calendar year from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf varieties such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may increase as extra tall as 80 cm.
The plants are scapose, having an individual central leafless hollow blossom stem (scape). Several blue-green or green, narrow, strap-shaped leaves happen from the bulb. The plant stem bears a solitary bloom, but sometimes a cluster of bouquets (umbel). The bouquets, which can be conspicuous and white or yellow usually, both or hardly ever green sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an external ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical shaped corona. The bouquets may hang up down (pendent), or be erect. You will discover six pollen bearing stamens adjoining a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The berries contains a dried capsule that splits (dehisces) liberating numerous black seed products.
The bulb is situated dormant after the leaves and blossom stem die back and has contractile roots that move it down further into the soil. The bloom leaves and stem form in the light, to emerge the next season. Most kinds are dormant from warmer summer months to late winter, flowering in the spring, though a few species are fall flowering.
