Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common brands 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 bouquets are usually white or yellow (orange or red in garden kinds), with either uniform 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 Kinds Plantarum (1753). The genus is generally considered to have about ten sections with about 50 species. The number of species has mixed, depending about how they are labeled, as a consequence to similarity between hybridization and types. 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 unfamiliar, but it is often linked to a Greek phrase for intoxicated (narcotic) and the misconception of the youth of that name who fell in love with his own representation. The English phrase 'daffodil' is apparently produced from "asphodel", with which it was compared commonly.
The types are local to meadows and woods in southern European countries and North Africa with a center of diversity in the European Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were launched in to the ASIA to the tenth century prior. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are insect-pollinated also. Known pests, diseases and disorders 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 increasingly popular in Europe following the 16th century and by the overdue 19th hundred years were an important commercial crop centred primarily on holland. Today narcissi are popular as trim blooms so when ornamental plants in private and general population gardens. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering an array of colours and shapes. Like other members of their family, narcissi produce a number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested accidentally. This property has been exploited for medicinal utilization in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in literature and artwork, narcissi are associated with a true number of themes in several cultures, ranging from loss of life to fortune, and as symbols of planting season. The daffodil is the countrywide rose of Wales and the icon 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 after flowering with an underground storage bulb. They regrow in the next year from brown-skinned ovoid bulbs with pronounced necks, and reach levels of 5-80 cm with respect to the species. Dwarf species such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may increase as high as 80 cm.
The plants are scapose, having a single central leafless hollow rose stem (scape). Several blue-green or green, small, strap-shaped leaves happen from the light. The place stem bears a solitary flower, but occasionally a cluster of blooms (umbel). The blossoms, which can be conspicuous and white or yellow usually, sometimes both or rarely green, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube 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 plants may suspend down (pendent), or be erect. You can find six pollen bearing stamens surrounding a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The fruits consists of a dried up capsule that splits (dehisces) launching numerous black seeds.
The bulb is situated dormant after the leaves and flower stem die again and has contractile roots that yank it down further in to the soil. The bloom stem and leaves form in the light, to emerge the next season. Most varieties are dormant from summer to past due winter, flowering in the spring, though a few species are fall months flowering.
