Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common titles 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 the cup- or trumpet-shaped corona. The blossoms are generally white or yellowish (orange or green in garden types), with either uniform or contrasting coloured tepals and corona.
Narcissus were well known in early civilisation, both medicinally and botanically, but formally described by Linnaeus in his Kinds Plantarum (1753). The genus is normally thought to have about ten sections with roughly 50 species. The amount of types has varied, depending on how they are labeled, due 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 true name Narcissus is unidentified, but it is often linked to a Greek expression for intoxicated (narcotic) and the misconception of the junior 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 compared commonly.
The species are native to meadows and woods in southern Europe and North Africa with a middle of diversity in the Western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were launched 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, nematodes and mites. 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 increasingly popular in Europe following the 16th century and by the late 19th hundred years were an important commercial crop centred mainly on the Netherlands. Narcissi are popular as slash blossoms so when ornamental plants in private and 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 an array of shapes and colours. Like other members of these 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 within traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in artwork and literature, narcissi are associated with a number of themes in various cultures, ranging from death to fortune, and as symbols of spring and coil. The daffodil is the countrywide rose of Wales and the image of cancer charities in many countries. The appearance of the outdoors flowers in spring and coil 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 calendar year from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm depending on the species. Dwarf types such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may increase as large as 80 cm.
The vegetation are scapose, having an individual central leafless hollow rose stem (scape). Several green or blue-green, small, strap-shaped leaves happen from the light. The plant stem bears a solitary flower, but occasionally a cluster of blooms (umbel). The bouquets, which 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 pipe above the ovary, then an outer ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical designed corona. The blossoms may suspend down (pendent), or be erect. You will discover six pollen bearing stamens encompassing a central style. The ovary is substandard (below the floral parts) consisting of three chambers (trilocular). The berry involves a dried capsule that splits (dehisces) launching numerous black seeds.
The bulb sits dormant after the leaves and flower stem die again and has contractile origins that yank it down further in to the soil. The blossom leaves and stem form in the bulb, to emerge the following season. Most varieties are dormant from warmer summer months to overdue winter, flowering in the spring, though a few species are fall flowering.
