Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial crops 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 by the cup- or trumpet-shaped corona. The blooms are usually white or yellow (orange or red in garden varieties), with either standard or contrasting colored tepals and corona.
Narcissus were popular in ancient civilisation, both medicinally and botanically, but formally defined by Linnaeus in his Species Plantarum (1753). The genus is generally considered to have about ten portions with roughly 50 species. The true quantity of varieties has varied, depending on how they are labeled, thanks to similarity between hybridization and species. 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 origins of the name Narcissus is unknown, but it is associated with a Greek term for intoxicated (narcotic) and the myth of the junior of that name who fell in love with his own representation. The English word 'daffodil' appears to be derived from "asphodel", with which it was commonly compared.
The varieties are native to meadows and woods in southern Europe and North Africa with a centre of variety in the Traditional western Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were created in to the ASIA to the tenth hundred years prior. Narcissi tend to be long-lived bulbs, which propagate by division, but are insect-pollinated also. 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 urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe following the 16th hundred years and by the past due 19th hundred years were an important commercial crop centred primarily on the Netherlands. Narcissi are popular as lower blossoms 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 categorized into divisions, covering a wide range of shapes and colours. Like other members with 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 books and artwork, narcissi are associated with a true number of themes in various cultures, ranging from death to good fortune, and as symbols of spring. The daffodil is the nationwide rose of Wales and the sign of tumors charities in many countries. The looks of the untamed flowers in spring is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering to the underground storage light. They regrow in the next season from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm with respect to the species. Dwarf kinds such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may increase as extra tall as 80 cm.
The vegetation are scapose, having a single central leafless hollow blossom stem (scape). Several blue-green or green, small, strap-shaped leaves occur from the bulb. The place stem usually bears a solitary bloom, but sometimes a cluster of plants (umbel). The plants, that are usually conspicuous and white or yellow, both or seldom inexperienced sometimes, contain 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 disc to conical shaped corona. The bouquets may hang down (pendent), or be erect. A couple of six pollen bearing stamens adjoining a central style. The ovary is inferior (below the floral parts) consisting of three chambers (trilocular). The fruit contains a dried out capsule that splits (dehisces) releasing numerous black seeds.
The bulb is placed dormant after the leaves and blossom stem die again and has contractile roots that yank it down further into the soil. The blossom leaves and stem form in the bulb, to emerge the following season. Most varieties are dormant from summer season to past due winter, flowering in the spring, though a few species are autumn flowering.
