Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common labels including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are being used to describe all or some known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by a cup- or trumpet-shaped corona. The plants are generally white or yellowish (orange or pink in garden varieties), with either even or contrasting colored tepals and corona.
Narcissus were well known in historical civilisation, both and botanically medicinally, but formally defined by Linnaeus in his Kinds Plantarum (1753). The genus is normally considered to have about ten areas with around 50 species. The true quantity of kinds has assorted, depending on how they are categorized, scheduled to similarity between types and hybridization. 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 true name Narcissus is undiscovered, but it is linked to a Greek term for intoxicated (narcotic) and the misconception of the junior of that name who fell deeply in love with his own reflection. The English word 'daffodil' appears to be derived from "asphodel", with which it was commonly compared.
The types are native to meadows and woods in southern Europe and North Africa with a center of variety in the Western Mediterranean, particularly the Iberian peninsula. Both wild and cultivated 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 insect-pollinated also. Known pests, disorders and diseases include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have grown to be extinct, while some are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the initial times, but became ever more popular in Europe after the 16th hundred years and by the later 19th hundred years were an important commercial crop centred mostly on holland. Narcissi are popular as chop blooms and since ornamental plants in private and general public gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a wide range of shapes and colours. Like other members of their family, narcissi create a 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 led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in books and skill, narcissi are associated with a true number of themes in various cultures, ranging from loss of life to fortune, and as icons of springtime. The daffodil is the nationwide blossom of Wales and the sign of tumor 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 back again after flowering for an underground storage bulb. They regrow in the next season 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 may grow as tall as 80 cm.
The crops are scapose, having an individual central leafless hollow rose stem (scape). Several blue-green or green, thin, strap-shaped leaves come up from the bulb. The plant stem usually bears a solitary bloom, but occasionally a cluster of flowers (umbel). The bouquets, that happen to be conspicuous and white or yellow usually, both or almost never inexperienced sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an exterior ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical shaped corona. The plants may hang down (pendent), or be erect. You will find six pollen bearing stamens encircling a central style. The ovary is substandard (below the floral parts) consisting of three chambers (trilocular). The berry involves a dry out capsule that splits (dehisces) launching numerous black seeds.
The bulb is dormant following the leaves and rose stem die back and has contractile root base that move it down further into the soil. The blossom leaves and stem form in the light, to emerge the following season. Most varieties are dormant from summer time to later winter, flowering in the planting season, though a few kinds are autumn flowering.
