Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial crops 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 with a cup- or trumpet-shaped corona. The blooms are usually white or yellow (orange or green in garden types), with either uniform or contrasting colored corona and tepals.
Narcissus were popular in historical civilisation, both medicinally and botanically, but formally explained by Linnaeus in his Kinds Plantarum (1753). The genus is generally considered to have about ten sections with around 50 species. The amount of varieties has mixed, depending on how they are grouped, credited to similarity between types and hybridization. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The exact origin of the name Narcissus is anonymous, but it is often associated with a Greek term for intoxicated (narcotic) and the myth of the youth of this name who fell deeply in love with his own reflection. The English word 'daffodil' is apparently produced from "asphodel", with which it was commonly likened.
The varieties are native to meadows and woods in southern Europe and North Africa with a centre of diversity in the Traditional western Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were launched into the Far East to the tenth hundred years prior. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are also insect-pollinated. Known pests, disorders and diseases include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have become extinct, while others 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 century and by the past due 19th hundred years were an important commercial crop centred mostly on the Netherlands. Narcissi are popular as chop flowers and as ornamental plants in private and public gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering a variety of shapes and colours. Like other members with their family, narcissi produce a 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 books and skill, narcissi are associated with a number of themes in different cultures, ranging from fatality to fortune, and as symbols of planting season. The daffodil is the nationwide flower of Wales and the symbol of cancers charities in many countries. The looks of the untamed flowers in spring is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to a underground storage light. They regrow in the following 12 months from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm depending on species. Dwarf kinds such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may grow as high as 80 cm.
The vegetation are scapose, having an individual central leafless hollow flower stem (scape). Several blue-green or green, narrow, strap-shaped leaves arise from the bulb. The place stem bears a solitary bloom, but once in a while a cluster of blossoms (umbel). The plants, which can be usually conspicuous and white or yellowish, both or almost never inexperienced sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an external ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical formed corona. The blooms may hang up down (pendent), or be erect. There are six pollen bearing stamens bordering a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The berries includes a dry capsule that splits (dehisces) liberating numerous black seed products.
The bulb sits dormant following the leaves and flower stem die again and has contractile root base that yank it down further into the soil. The blossom leaves and stem form in the light, to emerge the next season. Most species are dormant from summertime to later winter, flowering in the planting season, though a few types are fall months flowering.
