Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common labels including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are used to describe all or some 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 pink in garden varieties), with either standard or contrasting colored tepals and corona.
Narcissus were well known in traditional civilisation, both medicinally and botanically, but formally referred to by Linnaeus in his Varieties Plantarum (1753). The genus is generally thought to have about ten portions with approximately 50 species. The number of kinds has varied, depending how they are classified, scheduled to similarity between types and hybridization. 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 origins of the real name Narcissus is unknown, but it is often linked to a Greek phrase for intoxicated (narcotic) and the myth of the young ones of that name who fell in love with his own reflection. The English phrase 'daffodil' is apparently derived from "asphodel", with which it was compared commonly.
The kinds are local to meadows and woods in southern Europe and North Africa with a center of diversity in the American Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were released into the Far East to the tenth century 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 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 increasingly popular in Europe after the 16th century and by the past due 19th century were an important commercial crop centred generally on the Netherlands. Narcissi are popular as lower bouquets as ornamental vegetation in private and general public gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering an array of shapes and colours. Like other members of their family, narcissi create 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 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 true number of themes in various cultures, ranging from loss of life to fortune, and as icons of spring and coil. The daffodil is the nationwide bloom of Wales and the icon of cancers charities in many countries. The looks of the outrageous flowers in spring is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to an underground storage light 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 varieties such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may increase as high as 80 cm.
The vegetation are scapose, having a single central leafless hollow bloom stem (scape). Several green or blue-green, thin, strap-shaped leaves occur from the light bulb. The flower stem usually bears a solitary bloom, but once in a while a cluster of blooms (umbel). The blossoms, which are usually conspicuous and white or yellowish, both or hardly ever renewable 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 disk to conical formed corona. The plants may hang down (pendent), or be erect. You will discover six pollen bearing stamens adjoining a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The fruits includes a dried up capsule that splits (dehisces) releasing numerous black seeds.
The bulb is situated dormant after the leaves and flower stem die again and has contractile roots that take it down further in to the soil. The flower stem and leaves form in the light bulb, to emerge the next season. Most kinds are dormant from summer months to past due winter, flowering in the planting season, though a few types are autumn flowering.
