Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common titles 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 by a cup- or trumpet-shaped corona. The blossoms are generally white or yellow (orange or pink in garden kinds), with either even or contrasting coloured tepals and corona.
Narcissus were popular in old civilisation, both medicinally and botanically, but formally identified by Linnaeus in his Species Plantarum (1753). The genus is generally considered to have about ten portions with roughly 50 species. The true volume of types has mixed, depending on how they are classified, due to similarity between kinds and hybridization. The genus arose some right amount of time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise origin of the name Narcissus is unknown, but it is often associated with a Greek word for intoxicated (narcotic) and the misconception of the junior of that name who fell in love with his own reflection. The English word 'daffodil' appears to be produced from "asphodel", with which it was compared commonly.
The kinds are local to meadows and woods in southern European countries and North Africa with a centre of diversity in the European Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were introduced in to the Far East before 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, nematodes and mites. Some Narcissus species have grown to be extinct, while others are threatened by increasing urbanisation and tourism.
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 past due 19th century were an important commercial crop centred primarily on the Netherlands. Narcissi are popular as cut bouquets and since ornamental plant life in private and open public gardens today. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a wide range of shapes and colours. 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 accidentally. This property has been exploited for medicinal use within traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in art work and literature, narcissi are associated with a true number of themes in several cultures, ranging from loss of life to fortune, and as icons of spring and coil. The daffodil is the national blossom of Wales and the mark of tumors charities in many countries. The appearance of the outrageous flowers in spring is associated with festivals 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 12 months from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm depending on species. Dwarf types such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may increase as tall as 80 cm.
The vegetation are scapose, having a single central leafless hollow rose stem (scape). Several green or blue-green, small, strap-shaped leaves come up from the bulb. The seed stem usually bears a solitary flower, but occasionally a cluster of bouquets (umbel). The flowers, which can be conspicuous and white or yellowish usually, both or seldom renewable sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an external ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical molded corona. The bouquets may hang down (pendent), or be erect. There are six pollen bearing stamens adjoining a central style. The ovary is inferior (below the floral parts) consisting of three chambers (trilocular). The super fruit includes a dry out capsule that splits (dehisces) liberating numerous black seed products.
The bulb is placed dormant after the leaves and flower stem die back again and has contractile root base that yank it down further into the soil. The bloom leaves and stem form in the light, to emerge the following season. Most types are dormant from summer time to past due winter, flowering in the spring and coil, though a few kinds are fall months flowering.
