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 bouquets are usually white or yellow (orange or green in garden varieties), with either uniform or contrasting coloured tepals and corona.
Narcissus were popular in ancient civilisation, both medicinally and botanically, but formally detailed by Linnaeus in his Kinds Plantarum (1753). The genus is generally considered to have about ten areas with around 50 species. The amount of species has mixed, depending about how they are classified, as a consequence to similarity between hybridization and kinds. The genus arose some right amount of time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact origin of the name Narcissus is anonymous, but it is often linked to a Greek expression for intoxicated (narcotic) and the myth of the young ones of this name who fell deeply in love with his own representation. The English word 'daffodil' appears to be derived from "asphodel", with which it was likened commonly.
The kinds are local to meadows and woods in southern European countries and North Africa with a middle of diversity in the American Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were presented in to the ASIA to the tenth century prior. Narcissi tend 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, nematodes and mites. Some Narcissus species have become extinct, while others are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe following the 16th century and by the past due 19th hundred years were an important commercial crop centred mainly on holland. Today narcissi are popular as trim bouquets and since ornamental plant life in private and open public gardens. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a variety of shapes and colours. Like other members of their 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 resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in books and artwork, narcissi are associated with a true number of themes in several cultures, ranging from death to fortune, and as symbols of spring and coil. The daffodil is the national blossom of Wales and the sign of tumors charities in many countries. The appearance of the crazy flowers in planting season is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering with an underground storage light bulb. They regrow in the next time from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm depending on species. Dwarf varieties such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may develop as extra tall as 80 cm.
The crops are scapose, having a single central leafless hollow blossom stem (scape). Several blue-green or green, small, strap-shaped leaves happen from the light bulb. The flower stem bears a solitary flower, but sometimes a cluster of flowers (umbel). The plants, that happen to be 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 outside ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical designed corona. The bouquets may suspend down (pendent), or be erect. A couple of six pollen bearing stamens adjoining a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The berries consists of a dry capsule that splits (dehisces) liberating numerous black seeds.
The bulb lays dormant after the leaves and blossom stem die back again and has contractile origins that yank it down further in to the soil. The bloom leaves and stem form in the light, to emerge the following season. Most species are dormant from summertime to past due winter, flowering in the spring, though a few varieties are autumn flowering.
