Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common brands 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 the cup- or trumpet-shaped corona. The bouquets are generally white or yellow (orange or green in garden kinds), with either uniform or contrasting colored corona and tepals.
Narcissus were popular in traditional civilisation, both and botanically medicinally, but formally detailed by Linnaeus in his Kinds Plantarum (1753). The genus is normally thought to have about ten parts with about 50 species. The true volume of varieties has assorted, depending about how they are categorized, anticipated to similarity between varieties 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 precise origins of the name Narcissus is unknown, but it is often linked to a Greek word for intoxicated (narcotic) and the myth of the young ones of that name who fell in love with his own reflection. The English expression 'daffodil' is apparently produced from "asphodel", with which it was likened commonly.
The kinds are native to meadows and woods in southern European countries and North Africa with a centre of variety in the Traditional western Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were introduced into the Far East before the tenth century. Narcissi tend 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 initial times, but became ever more popular in Europe following the 16th century and by the overdue 19th hundred years were an important commercial crop centred mainly on the Netherlands. Today narcissi are popular as chop blossoms and as ornamental crops in private and public gardens. The long history of breeding has resulted in 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 these family, narcissi produce a true 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 use within traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in books and art work, narcissi are associated with a true number of themes in several cultures, ranging from fatality to good fortune, and as symbols of springtime. The daffodil is the countrywide blossom of Wales and the icon of cancer tumor charities in many countries. The appearance of the outdoors flowers in spring and coil is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering to an underground storage light. They regrow in the next year from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf varieties such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might increase as high as 80 cm.
The plants are scapose, having an individual central leafless hollow bloom stem (scape). Several green or blue-green, small, strap-shaped leaves occur from the light bulb. The seed stem usually bears a solitary flower, but occasionally a cluster of flowers (umbel). The flowers, that happen to be usually conspicuous and white or yellowish, both or seldom renewable sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outside ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical designed corona. The flowers may hang down (pendent), or be erect. There are six pollen bearing stamens adjoining a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The fruits involves a dried out capsule that splits (dehisces) launching numerous black seeds.
The bulb is situated dormant after the leaves and blossom stem die back again and has contractile origins that move it down further in to the soil. The rose stem and leaves form in the light, to emerge the next season. Most varieties are dormant from summer season to late winter, flowering in the planting season, though a few varieties are fall months flowering.
