Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common labels including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are being used to describe all or some members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by a cup- or trumpet-shaped corona. The blooms are usually white or yellow (orange or red in garden types), with either uniform or contrasting colored corona and tepals.
Narcissus were popular in historic civilisation, both and botanically medicinally, but formally referred to by Linnaeus in his Kinds Plantarum (1753). The genus is normally considered to have about ten areas with around 50 species. The true quantity of species has varied, depending about how they are grouped, 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 areas of southwest Europe. The exact source of the name Narcissus is mysterious, but it is often linked to a Greek phrase for intoxicated (narcotic) and the misconception of the youth of this name who fell in love with his own representation. The English word 'daffodil' appears to be produced from "asphodel", with which it was commonly likened.
The kinds are native to meadows and woods in southern Europe and North Africa with a centre of diversity in the Western Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were presented into the ASIA to the tenth hundred years prior. Narcissi have a tendency 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 some are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the initial times, but became ever more popular in Europe after the 16th hundred years and by the late 19th century were an important commercial crop centred mostly on holland. Today narcissi are popular as trim blossoms and as ornamental plant life in private and general population gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering a wide range of shapes and colours. Like other members with their family, narcissi create a 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 use within traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in literature and art, narcissi are associated with a number of themes in various cultures, ranging from fatality to good fortune, and as icons of springtime. The daffodil is the countrywide blossom of Wales and the image of cancer tumor charities in many countries. The appearance of the untamed flowers in springtime is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to the underground storage bulb. They regrow in the following season from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm with regards 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 an individual central leafless hollow blossom stem (scape). Several green or blue-green, thin, strap-shaped leaves occur from the light bulb. The vegetable stem usually bears a solitary bloom, but occasionally a cluster of blooms (umbel). The plants, which can be conspicuous and white or yellow usually, sometimes both or hardly ever inexperienced, 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 disc to conical shaped corona. The blossoms may hang up 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 fruit contains a dried up capsule that splits (dehisces) liberating numerous black seeds.
The bulb is situated dormant following the leaves and blossom stem die back and has contractile roots that yank it down further in to the soil. The flower stem and leaves form in the bulb, to emerge the next season. Most species are dormant from summer to late winter, flowering in the spring and coil, though a few species are fall months flowering.
