Narcissus /n?:r's?s?s/ is a genus of mainly 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 with a cup- or trumpet-shaped corona. The plants are generally white or yellow (orange or pink in garden kinds), with either uniform or contrasting colored corona and tepals.
Narcissus were popular in historic civilisation, both medicinally and botanically, but formally explained by Linnaeus in his Species Plantarum (1753). The genus is normally thought to have about ten areas with about 50 species. The true number of kinds has mixed, depending on how they are categorized, as a consequence 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 origin of the name Narcissus is anonymous, but it is associated with a Greek expression for intoxicated (narcotic) and the myth of the junior of that name who fell in love with his own reflection. The English term 'daffodil' appears to be produced from "asphodel", with which it was compared commonly.
The kinds are indigenous to meadows and woods in southern Europe and North Africa with a middle of diversity in the American Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were introduced into the Far East before the tenth century. 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, nematodes and mites. 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 initial 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 mainly on holland. Narcissi are popular as chop flowers so that ornamental plants in private and general public gardens today. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering an array of shapes and colours. Like other members of the family, narcissi create 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 use within traditional healing and has resulted in 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 different cultures, ranging from death to good fortune, and as symbols of spring. The daffodil is the national bloom of Wales and the icon of tumors charities in many countries. The looks of the untamed flowers in springtime 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 year from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm with respect to the species. Dwarf kinds such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might develop as large as 80 cm.
The vegetation are scapose, having an individual central leafless hollow rose stem (scape). Several green or blue-green, thin, strap-shaped leaves happen from the light. The flower stem bears a solitary flower, but sometimes a cluster of plants (umbel). The bouquets, which can be usually conspicuous and white or yellow, both or hardly ever inexperienced sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outer ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical shaped corona. The flowers 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) consisting of three chambers (trilocular). The berries involves a dried out capsule that splits (dehisces) releasing numerous black seeds.
The bulb is situated dormant after the leaves and bloom stem die back again and has contractile root base that yank it down further in to the soil. The flower stem and leaves form in the bulb, to emerge the following season. Most types are dormant from summertime to late winter, flowering in the springtime, though a few kinds are fall flowering.
