Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial vegetation 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 way of a cup- or trumpet-shaped corona. The bouquets are usually white or yellow (orange or red in garden kinds), with either uniform or contrasting colored corona and tepals.
Narcissus were well known in old civilisation, both and botanically medicinally, but formally referred to by Linnaeus in his Varieties Plantarum (1753). The genus is generally thought to have about ten portions with roughly 50 species. The amount of species has mixed, depending how they are categorised, as a consequence to similarity between hybridization and species. 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 real name Narcissus is mysterious, but it is associated with a Greek expression for intoxicated (narcotic) and the misconception of the young ones of that name who fell in love with his own reflection. The English term 'daffodil' appears to be derived from "asphodel", with which it was commonly likened.
The kinds are indigenous to meadows and woods in southern European countries 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 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 insect-pollinated also. Known pests, disorders and diseases include viruses, fungi, the larvae of flies, mites and nematodes. 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 century and by the overdue 19th century were an important commercial crop centred mainly on the Netherlands. Narcissi are popular as slash flowers and since ornamental vegetation in private and general population gardens today. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a variety of colours and shapes. Like other members of their family, narcissi produce a true 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 used in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in art work and literature, 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 national blossom of Wales and the sign of cancer tumor 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 after flowering to a underground storage bulb. They regrow in the next year from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm with respect to the species. Dwarf types such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might increase as large as 80 cm.
The plants are scapose, having an individual central leafless hollow flower stem (scape). Several blue-green or green, slim, strap-shaped leaves happen from the light bulb. The vegetable stem bears a solitary blossom, but once in a while a cluster of blooms (umbel). The blossoms, which can be conspicuous and white or yellow usually, both or rarely inexperienced sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outside ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical molded corona. The bouquets may hang up down (pendent), or be erect. You will discover six pollen bearing stamens surrounding a central style. The ovary is inferior (below the floral parts) consisting of three chambers (trilocular). The fruit includes a dried capsule that splits (dehisces) liberating numerous black seed products.
The bulb is dormant after the leaves and blossom stem die back again and has contractile origins that yank it down further into the soil. The rose stem and leaves form in the light, to emerge the following season. Most kinds are dormant from summer to later winter, flowering in the planting season, though a few types are autumn flowering.
