Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common names 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 way of a cup- or trumpet-shaped corona. The flowers are generally white or yellowish (orange or green in garden kinds), with either uniform or contrasting colored tepals and corona.
Narcissus were popular in historical civilisation, both and botanically medicinally, but formally explained by Linnaeus in his Species Plantarum (1753). The genus is generally considered to have about ten sections with around 50 species. The number of species has mixed, depending on how they are classified, anticipated to similarity between species 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 unidentified, but it is often linked to a Greek phrase for intoxicated (narcotic) and the misconception of the youngsters of this name who fell in love with his own reflection. The English expression 'daffodil' is apparently derived from "asphodel", with which it was commonly compared.
The species are native to meadows and woods in southern European countries and North Africa with a middle of diversity in the Western Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were released into the Far East to the tenth hundred years prior. 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 others are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the initial times, but became ever more popular in Europe after the 16th hundred years and by the late 19th century were an important commercial crop centred mainly on the Netherlands. Narcissi are popular as slice blooms so when ornamental plant life in private and general public gardens today. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering a wide range of colours and shapes. 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 accidentally ingested. This property has been exploited for medicinal used in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in skill and books, narcissi are associated with a number of themes in different cultures, ranging from loss of life to fortune, and as icons of planting season. The daffodil is the nationwide bloom of Wales and the icon of cancer tumor charities in many countries. The looks 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 yr from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf species such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might grow as extra tall as 80 cm.
The plants are scapose, having a single central leafless hollow flower stem (scape). Several blue-green or green, slim, strap-shaped leaves happen from the light. The seed stem usually bears a solitary flower, but occasionally a cluster of blooms (umbel). The flowers, which can be conspicuous and white or yellow usually, sometimes both or almost never inexperienced, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outer ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The plants may hang up down (pendent), or be erect. You can find six pollen bearing stamens bordering a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The berry contains a dried up capsule that splits (dehisces) liberating numerous black seed products.
The bulb is dormant after the leaves and bloom stem die back and has contractile root base that pull it down further in to the soil. The rose leaves and stem form in the light bulb, to emerge the next season. Most kinds are dormant from summer time to overdue winter, flowering in the spring and coil, though a few types are autumn flowering.
