Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial vegetation 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 by a cup- or trumpet-shaped corona. The plants are usually white or yellow (orange or green in garden kinds), with either standard or contrasting colored corona and tepals.
Narcissus were popular in early civilisation, both and botanically medicinally, but formally explained by Linnaeus in his Varieties Plantarum (1753). The genus is normally considered to have about ten areas with around 50 species. The number of kinds has assorted, depending about how they are classified, a consequence of to similarity between hybridization and varieties. The genus arose some right time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact origins of the name Narcissus is mysterious, but it is linked to a Greek term for intoxicated (narcotic) and the misconception of the children of that name who fell in love with his own reflection. The English word 'daffodil' appears to be derived from "asphodel", with which it was commonly compared.
The types are local to meadows and woods in southern European countries and North Africa with a center of diversity in the European Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were released into the Far East to the tenth century prior. Narcissi tend to be long-lived bulbs, which propagate by division, but are insect-pollinated also. Known pests, diseases and disorders include viruses, fungi, the larvae of flies, nematodes and mites. Some Narcissus species have become extinct, while others are threatened by increasing tourism and urbanisation.
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 late 19th hundred years were an important commercial crop centred mainly on the Netherlands. Today narcissi are popular as cut blossoms so that ornamental vegetation in private and general public gardens. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering a variety of shapes and colours. Like other members of these family, narcissi create a 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 used in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in literature and art, narcissi are associated with a true number of themes in different cultures, ranging from fatality to good fortune, and as symbols of spring. The daffodil is the countrywide rose of Wales and the symbol of cancers charities in many countries. The looks of the outdoors flowers in springtime is associated with celebrations 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 next year from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm depending on the species. Dwarf types such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may grow as extra tall as 80 cm.
The crops are scapose, having a single central leafless hollow rose stem (scape). Several green or blue-green, small, strap-shaped leaves happen from the bulb. The place stem usually bears a solitary blossom, but sometimes a cluster of blossoms (umbel). The flowers, which can be conspicuous and white or yellow usually, sometimes both or seldom renewable, 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 down (pendent), or be erect. You will discover six pollen bearing stamens bordering a central style. The ovary is inferior (below the floral parts) consisting of three chambers (trilocular). The fruit consists of a dried out capsule that splits (dehisces) launching numerous black seed products.
The bulb lies dormant after the leaves and blossom stem die again and has contractile origins that draw it down further in to the soil. The flower stem and leaves form in the light bulb, to emerge the following season. Most species are dormant from summer season to past due winter, flowering in the spring, though a few varieties are fall months flowering.
