Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common titles 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 with a cup- or trumpet-shaped corona. The flowers are usually white or yellowish (orange or pink in garden varieties), with either standard or contrasting coloured tepals and corona.
Narcissus were popular in old civilisation, both and botanically medicinally, but formally explained by Linnaeus in his Types Plantarum (1753). The genus is normally considered to have about ten areas with around 50 species. The true variety of varieties has assorted, depending on how they are grouped, a consequence of to similarity between hybridization and types. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact origin of the real name Narcissus is mysterious, but it is associated with a Greek expression for intoxicated (narcotic) and the myth of the youngsters of this name who fell in love with his own reflection. The English expression 'daffodil' appears to be produced from "asphodel", with which it was commonly likened.
The kinds are indigenous to meadows and woods in southern European countries and North Africa with a middle of variety in the Western Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were introduced into the Far East before the tenth century. Narcissi have a tendency 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 earliest times, but became ever more popular in Europe after the 16th century and by the overdue 19th century were an important commercial crop centred mainly on the Netherlands. Narcissi are popular as cut bouquets and since ornamental plants in private and open public gardens today. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a variety of shapes and colours. 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 inadvertently. 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 skill and literature, narcissi are associated with a number of themes in several cultures, ranging from fatality to good fortune, and as icons of spring and coil. The daffodil is the nationwide rose of Wales and the icon of malignancy charities in many countries. The appearance of the outdoors flowers in spring is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to 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 species. Dwarf kinds such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might increase as extra tall as 80 cm.
The plants are scapose, having a single central leafless hollow bloom stem (scape). Several blue-green or green, narrow, strap-shaped leaves come up from the light. The flower stem bears a solitary blossom, but once in a while a cluster of blooms (umbel). The plants, which are usually conspicuous and white or yellow, both or rarely inexperienced sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an external ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical formed corona. The bouquets may suspend down (pendent), or be erect. You will discover six pollen bearing stamens surrounding a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The berries includes a dried capsule that splits (dehisces) liberating numerous black seeds.
The bulb is situated dormant following the leaves and rose stem die back again and has contractile origins that take it down further in to the soil. The blossom leaves and stem form in the bulb, to emerge the next season. Most kinds are dormant from summer months to late winter, flowering in the spring and coil, though a few species are autumn flowering.
