Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common names 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 blossoms are generally white or yellowish (orange or green in garden varieties), with either uniform or contrasting colored tepals and corona.
Narcissus were well known in historical civilisation, both medicinally and botanically, but formally explained by Linnaeus in his Species Plantarum (1753). The genus is generally thought to have about ten parts with approximately 50 species. The number of varieties has varied, depending how they are categorized, as a consequence to similarity between hybridization and types. The genus arose some right amount of time 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 unknown, but it is associated with a Greek word for intoxicated (narcotic) and the myth of the youth of that name who fell in love with his own reflection. The English term 'daffodil' appears to be produced from "asphodel", with which it was compared commonly.
The types are native to meadows and woods in southern European countries and North Africa with a center of diversity in the Traditional western Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were presented in to the Far East to the tenth hundred years 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, 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 ever more popular in Europe following the 16th hundred years and by the late 19th century were an important commercial crop centred generally on holland. Narcissi are popular as trim flowers so that as ornamental vegetation in private and public gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering an array of colours and shapes. Like other members with their 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 use in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in literature and fine art, narcissi are associated with a number of themes in various cultures, ranging from fatality to fortune, and as symbols of planting season. The daffodil is the countrywide bloom of Wales and the symbol of tumor charities in many countries. The appearance of the wild flowers in springtime is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering with an underground storage bulb. They regrow in the next time from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm with regards to the species. Dwarf kinds such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might grow as high as 80 cm.
The plant life are scapose, having a single central leafless hollow rose stem (scape). Several blue-green or green, small, strap-shaped leaves happen from the light. The seed stem usually bears a solitary bloom, but once in a while a cluster of blooms (umbel). The plants, which are usually conspicuous and white or yellow, both or almost never renewable sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an exterior ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical designed corona. The flowers may suspend 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 fruit consists of a dry capsule that splits (dehisces) liberating numerous black seeds.
The bulb lays dormant after the leaves and rose stem die back again and has contractile origins that move it down further into the soil. The bloom stem and leaves form in the light, to emerge the following season. Most species are dormant from summertime to late winter, flowering in the spring and coil, though a few species are fall flowering.
