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 being 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 blossoms are usually white or yellowish (orange or red in garden kinds), with either standard or contrasting colored corona and tepals.
Narcissus were popular in historical civilisation, both and botanically medicinally, but formally identified by Linnaeus in his Varieties Plantarum (1753). The genus is normally considered to have about ten portions with about 50 species. The true volume of species has varied, depending about how they are categorised, as a consequence to similarity between hybridization and types. The genus arose 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 undiscovered, but it is often associated with a Greek phrase for intoxicated (narcotic) and the misconception of the young ones of that name who fell in love with his own representation. The English word 'daffodil' is apparently derived from "asphodel", with which it was compared commonly.
The types are local to meadows and woods in southern European countries and North Africa with a centre of diversity in the Western Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were introduced in to the Far East before the tenth century. Narcissi tend 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 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 century and by the late 19th hundred years were an important commercial crop centred generally on holland. Today narcissi are popular as slash flowers and as 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 categorised into divisions, covering a variety of colours and shapes. Like other members of their family, narcissi create a 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 books and artwork, narcissi are associated with a number of themes in various cultures, ranging from fatality to fortune, and as symbols of spring. The daffodil is the national rose of Wales and the mark of 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 for an underground storage light bulb. They regrow in the following season from brown-skinned ovoid lights with pronounced necks, and reach heights 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 might grow as high as 80 cm.
The plants are scapose, having an individual central leafless hollow bloom stem (scape). Several blue-green or green, narrow, strap-shaped leaves occur from the bulb. The herb stem bears a solitary blossom, but once in a while a cluster of blossoms (umbel). The plants, which are usually conspicuous and white or yellow, both or seldom renewable sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outer ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical designed corona. The flowers may suspend down (pendent), or be erect. You can find six pollen bearing stamens encompassing a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The berry consists of a dry capsule that splits (dehisces) launching numerous black seed products.
The bulb sits dormant following the leaves and rose stem die again and has contractile root base that draw it down further in to the soil. The flower leaves and stem form in the bulb, to emerge the next season. Most kinds are dormant from summertime to late winter, flowering in the springtime, though a few types are fall months flowering.
