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 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 yellowish (orange or red in garden varieties), with either uniform or contrasting colored tepals and corona.
Narcissus were popular in historic civilisation, both medicinally and botanically, but formally identified by Linnaeus in his Kinds Plantarum (1753). The genus is normally thought to have about ten parts with about 50 species. The true quantity of species has mixed, depending how they are categorised, thanks to similarity between hybridization and kinds. The genus arose time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise source of the real name Narcissus is anonymous, but it is often associated with a Greek word for intoxicated (narcotic) and the misconception of the children of this name who fell in love with his own reflection. The English phrase 'daffodil' is apparently produced from "asphodel", with which it was commonly compared.
The varieties are indigenous to meadows and woods in southern European countries and North Africa with a centre of variety in the European Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were unveiled into the ASIA to the tenth century 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 tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe following the 16th century and by the overdue 19th century were an important commercial crop centred mainly on the Netherlands. Narcissi are popular as slash plants so that ornamental vegetation in private and open public gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering an array of colours and shapes. Like other members of their family, narcissi create 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 utilization in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in books and art work, narcissi are associated with a true number of themes in different cultures, ranging from loss of life to good fortune, and as icons of planting season. The daffodil is the nationwide rose of Wales and the icon of tumor charities in many countries. The looks of the crazy flowers in spring is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to the underground storage light bulb. They regrow in the next 12 months from brown-skinned ovoid 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 increase as tall as 80 cm.
The plants are scapose, having a single central leafless hollow bloom stem (scape). Several green or blue-green, thin, strap-shaped leaves occur from the light. The place stem bears a solitary bloom, but once in a while a cluster of blooms (umbel). The blossoms, which can be usually conspicuous and white or yellowish, sometimes both or hardly ever inexperienced, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an exterior ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical designed corona. The plants may suspend down (pendent), or be erect. There are six pollen bearing stamens encompassing a central style. The ovary is second-rate (below the floral parts) consisting of three chambers (trilocular). The fruit includes a dried capsule that splits (dehisces) releasing numerous black seed products.
The bulb lies dormant following the leaves and bloom stem die back again and has contractile origins that move it down further in to the soil. The blossom leaves and stem form in the bulb, to emerge the following season. Most types are dormant from warmer summer months to late winter, flowering in the spring and coil, though a few types are autumn flowering.
