Narcissus /n?:r's?s?s/ is a genus of mostly 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 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 pink in garden varieties), with either uniform or contrasting coloured tepals and corona.
Narcissus were popular in early civilisation, both and botanically medicinally, but formally described by Linnaeus in his Species Plantarum (1753). The genus is generally thought to have about ten portions with around 50 species. The amount of types has assorted, depending on how they are labeled, as a consequence to similarity between hybridization and kinds. 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 real name Narcissus is unfamiliar, but it is associated with a Greek phrase for intoxicated (narcotic) and the myth of the youngsters of that name who fell in love with his own reflection. The English term 'daffodil' is apparently produced from "asphodel", with which it was compared commonly.
The types are local to meadows and woods in southern Europe and North Africa with a middle of variety in the Traditional western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were unveiled in to the Far East to the tenth century prior. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are also insect-pollinated. Known pests, diseases and disorders include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have grown to be extinct, while others 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 after the 16th hundred years and by the past due 19th century were an important commercial crop centred primarily on holland. Today narcissi are popular as slash bouquets and as ornamental plant life in private and general population gardens. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering a wide range of shapes and colours. Like other members of the family, narcissi create 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 use in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in artwork and literature, narcissi are associated with a number of themes in various cultures, ranging from loss of life to fortune, and as icons of springtime. The daffodil is the nationwide flower of Wales and the mark of tumor charities in many countries. The looks of the wild flowers in springtime is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to the underground storage light bulb. They regrow in the next yr from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm depending on the species. Dwarf varieties such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might develop as tall as 80 cm.
The plant life are scapose, having an individual central leafless hollow rose stem (scape). Several green or blue-green, slim, strap-shaped leaves happen from the bulb. The seed stem usually bears a solitary bloom, but once in a while a cluster of flowers (umbel). The blooms, that are conspicuous and white or yellowish usually, sometimes both or hardly ever green, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an exterior ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The blossoms may hang down (pendent), or be erect. There are six pollen bearing stamens adjoining a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The fruit consists of a dried out capsule that splits (dehisces) releasing numerous black seed products.
The bulb sits dormant following the leaves and bloom stem die back again and has contractile roots that pull it down further in to the soil. The bloom leaves and stem form in the light, to emerge the next season. Most species are dormant from summer season to past due winter, flowering in the spring and coil, though a few types are autumn flowering.
