Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common brands 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 blooms are generally white or yellow (orange or green in garden types), with either standard or contrasting colored 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 portions with around 50 species. The true variety of species has varied, depending how they are categorised, a consequence of to similarity between hybridization and varieties. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise origins of the true name Narcissus is unfamiliar, but it is associated with a Greek term 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 derived from "asphodel", with which it was commonly compared.
The species are local to meadows and woods in southern European countries and North Africa with a centre of variety in the Western Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were introduced in to the Far East prior to the tenth century. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are also insect-pollinated. Known pests, disorders and diseases 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 after the 16th century and by the past due 19th century were an important commercial crop centred mostly on the Netherlands. Today narcissi are popular as trim blooms so that as 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 classified into divisions, covering a wide range 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 unintentionally. This property has been exploited for medicinal use in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in literature and skill, narcissi are associated with a true number of themes in several cultures, ranging from fatality to good fortune, and as icons of planting season. The daffodil is the nationwide blossom of Wales and the image of cancers charities in many countries. The appearance of the outdoors flowers in springtime is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to an underground storage bulb. They regrow in the following season from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm with respect to the species. Dwarf species such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might develop as extra tall as 80 cm.
The plant life are scapose, having a single central leafless hollow bloom stem (scape). Several blue-green or green, thin, strap-shaped leaves arise from the bulb. The place stem bears a solitary bloom, but occasionally a cluster of plants (umbel). The plants, that happen to be conspicuous and white or yellow usually, sometimes both or seldom renewable, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outside ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical molded corona. The flowers may hang up down (pendent), or be erect. A couple of six pollen bearing stamens adjoining a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The berry involves a dried capsule that splits (dehisces) launching numerous black seed products.
The bulb lies dormant following the leaves and bloom stem die again and has contractile origins that pull it down further in to the soil. The blossom leaves and stem form in the bulb, to emerge the next season. Most types are dormant from summertime to overdue winter, flowering in the spring, though a few kinds are fall flowering.
