Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common labels 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 with a cup- or trumpet-shaped corona. The blossoms are usually white or yellow (orange or green in garden varieties), with either standard or contrasting coloured corona and tepals.
Narcissus were well known in old civilisation, both and botanically medicinally, but formally described by Linnaeus in his Kinds Plantarum (1753). The genus is generally considered to have about ten areas with about 50 species. The number of types has assorted, depending on how they are categorized, due 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 precise origin of the real name Narcissus is unknown, but it is often linked to a Greek term for intoxicated (narcotic) and the myth of the youth of this name who fell in love with his own representation. The English phrase 'daffodil' appears to be derived from "asphodel", with which it was commonly compared.
The kinds are native to meadows and woods in southern Europe and North Africa with a middle of diversity in the American Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were introduced in to the Far East before 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 become extinct, while some are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe after the 16th hundred years and by the later 19th hundred years were an important commercial crop centred generally on holland. Today narcissi are popular as slash blooms so when ornamental plant life in private and public gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering a wide range of shapes and colours. Like other members of the 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 led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in skill and books, narcissi are associated with a true number of themes in several cultures, ranging from fatality to fortune, and as icons of springtime. The daffodil is the countrywide flower of Wales and the symbol of cancer tumor charities in many countries. The appearance of the outrageous flowers in springtime is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to an underground storage light. They regrow in the following calendar year from brown-skinned ovoid lights with pronounced necks, and reach levels 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 may increase as tall as 80 cm.
The crops are scapose, having an individual central leafless hollow bloom stem (scape). Several green or blue-green, narrow, strap-shaped leaves happen from the bulb. The flower stem usually bears a solitary blossom, but sometimes a cluster of plants (umbel). The bouquets, which are conspicuous and white or yellow usually, sometimes both or seldom green, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outer ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical molded corona. The blooms may hang up down (pendent), or be erect. You will discover six pollen bearing stamens adjoining a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The berries contains a dry out capsule that splits (dehisces) liberating numerous black seed products.
The bulb lies dormant after 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 light, to emerge the next season. Most species are dormant from summer season to late winter, flowering in the springtime, though a few varieties are fall flowering.
