Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plant life 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 known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by the cup- or trumpet-shaped corona. The blooms are usually white or yellowish (orange or pink in garden varieties), with either uniform or contrasting coloured corona and tepals.
Narcissus were popular in historical civilisation, both medicinally and botanically, but formally explained by Linnaeus in his Varieties Plantarum (1753). The genus is normally thought to have about ten portions with roughly 50 species. The true variety of kinds has varied, depending how they are categorised, anticipated to similarity between species 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 exact origin of the name Narcissus is mysterious, but it is often associated with a Greek term for intoxicated (narcotic) and the myth of the youngsters of this name who fell in love with his own reflection. The English term 'daffodil' is apparently derived from "asphodel", with which it was commonly compared.
The types are native to meadows and woods in southern Europe and North Africa with a center of variety in the Traditional western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were introduced into 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, 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 following the 16th century and by the late 19th hundred years were an important commercial crop centred generally on the Netherlands. Today narcissi are popular as slash plants so that ornamental plants in private and general public gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering a wide range of colours and shapes. Like other members of these family, narcissi produce a true 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 utilization in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in literature and art work, narcissi are associated with a true number of themes in various cultures, ranging from loss of life to good fortune, and as symbols of planting season. The daffodil is the nationwide flower of Wales and the sign of malignancy charities in many countries. The appearance of the crazy flowers in spring and coil 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 light. They regrow in the next time 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 elevation of 5-8 cm, while Narcissus tazetta might increase as tall as 80 cm.
The plants are scapose, having an individual central leafless hollow blossom stem (scape). Several green or blue-green, slim, strap-shaped leaves come up from the bulb. The flower stem usually bears a solitary blossom, but occasionally a cluster of plants (umbel). The flowers, which can be conspicuous and white or yellow usually, sometimes both or rarely 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 plants may hang down (pendent), or be erect. You can find six pollen bearing stamens adjoining a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The fruits involves a dried capsule that splits (dehisces) liberating numerous black seed products.
The bulb is situated dormant following the leaves and bloom stem die again and has contractile origins that yank it down further into the soil. The rose leaves and stem form in the light bulb, to emerge the next season. Most types are dormant from summer months to past due winter, flowering in the planting season, though a few species are fall months flowering.
