Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plant life 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 yellow (orange or red in garden varieties), with either even or contrasting coloured corona and tepals.
Narcissus were well known in traditional civilisation, both and botanically medicinally, but formally identified by Linnaeus in his Species Plantarum (1753). The genus is normally thought to have about ten areas with around 50 species. The true amount of species has assorted, depending how they are classified, due to similarity between kinds and hybridization. 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 precise origins of the name Narcissus is unfamiliar, but it is associated with a Greek term for intoxicated (narcotic) and the misconception of the youth of this name who fell in love with his own reflection. The English term 'daffodil' appears to be derived from "asphodel", with which it was commonly likened.
The kinds are local to meadows and woods in southern Europe and North Africa with a centre of variety in the Western Mediterranean, the Iberian peninsula particularly. 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, 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 ever more popular in Europe after the 16th hundred years and by the past due 19th hundred years were an important commercial crop centred primarily on the Netherlands. Today narcissi are popular as slash flowers so that as ornamental plants in private and open public gardens. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering an array of colours and shapes. Like other members of the family, narcissi produce a true 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 use within 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 good fortune, and as icons of spring. The daffodil is the countrywide blossom of Wales and the image of tumor charities in many countries. The looks 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 to the underground storage 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 kinds such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may increase as high as 80 cm.
The plant life are scapose, having a single central leafless hollow flower stem (scape). Several blue-green or green, narrow, strap-shaped leaves happen from the light. The place stem bears a solitary bloom, but once in a while a cluster of blossoms (umbel). The bouquets, which are usually conspicuous and white or yellowish, sometimes both or hardly ever inexperienced, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outer ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical designed corona. The flowers may hang up down (pendent), or be erect. You can find six pollen bearing stamens bordering a central style. The ovary is inferior (below the floral parts) consisting of three chambers (trilocular). The fruits consists of a dried out capsule that splits (dehisces) releasing numerous black seed products.
The bulb is dormant following the leaves and rose stem die again and has contractile origins that draw it down further into the soil. The blossom leaves and stem form in the light, to emerge the following season. Most types are dormant from summer months to overdue winter, flowering in the planting season, though a few kinds are fall flowering.
