Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common titles including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are 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 bouquets are generally white or yellowish (orange or green in garden varieties), with either standard or contrasting colored corona and tepals.
Narcissus were popular in traditional civilisation, both medicinally and botanically, but formally detailed by Linnaeus in his Varieties Plantarum (1753). The genus is generally considered to have about ten areas with about 50 species. The true variety of species has varied, depending on how they are labeled, scheduled to similarity between species and hybridization. The genus arose some 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 associated with a Greek word for intoxicated (narcotic) and the misconception of the young ones of this name who fell in love with his own representation. The English word 'daffodil' is apparently produced from "asphodel", with which it was likened commonly.
The species are native to meadows and woods in southern Europe and North Africa with a centre of diversity in the European Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were launched into the ASIA to the tenth hundred years prior. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are insect-pollinated also. Known pests, disorders and diseases include viruses, fungi, the larvae of flies, nematodes and mites. Some Narcissus species have grown to be extinct, while others are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became ever more popular in Europe following the 16th century and by the overdue 19th century were an important commercial crop centred generally on holland. Narcissi are popular as lower blossoms as ornamental plants in private and general public gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering an array of shapes and colours. Like other members of their family, narcissi create a true 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 led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in art work and literature, narcissi are associated with a number of themes in several cultures, ranging from fatality to good fortune, and as icons of spring. The daffodil is the nationwide flower of Wales and the sign of tumors charities in many countries. The looks of the wild flowers in springtime is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to a underground storage light bulb. They regrow in the following year from brown-skinned ovoid lights 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 may develop as tall as 80 cm.
The vegetation are scapose, having a single central leafless hollow rose stem (scape). Several green or blue-green, narrow, strap-shaped leaves come up from the light. The herb stem usually bears a solitary flower, but sometimes a cluster of bouquets (umbel). The bouquets, that happen to be usually conspicuous and white or yellowish, both or rarely renewable sometimes, consist of 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 designed corona. The blossoms may hang down (pendent), or be erect. You will find six pollen bearing stamens adjoining a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The fruit consists of a dried capsule that splits (dehisces) liberating numerous black seeds.
The bulb lays dormant following the leaves and rose stem die back again and has contractile origins that pull it down further into the soil. The blossom stem and leaves form in the bulb, to emerge the next season. Most kinds are dormant from summer months to overdue winter, flowering in the planting season, though a few varieties are autumn flowering.
