Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common labels including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are used to describe all or some 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 pink in garden varieties), with either standard or contrasting colored corona and tepals.
Narcissus were popular in historical civilisation, both and botanically medicinally, but formally referred to by Linnaeus in his Varieties Plantarum (1753). The genus is normally thought to have about ten portions with roughly 50 species. The true quantity of species has assorted, depending about how they are categorised, anticipated to similarity between species and hybridization. The genus arose some time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise origin of the true name Narcissus is anonymous, but it is linked to a Greek word for intoxicated (narcotic) and the misconception of the children of that name who fell deeply in love with his own representation. The English word 'daffodil' is apparently produced from "asphodel", with which it was commonly likened.
The types are native to meadows and woods in southern European countries and North Africa with a center of variety in the Western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were introduced into the Far East prior to the tenth century. Narcissi have a tendency 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, 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 earliest times, but became ever more popular in Europe following the 16th century and by the late 19th century were an important commercial crop centred mainly on holland. Today narcissi are popular as slash blooms so that ornamental plants in private and general public gardens. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a variety of colours and shapes. 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 ingested inadvertently. This property has been exploited for medicinal used in traditional healing and has resulted in 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 several cultures, ranging from loss of life to good fortune, and as icons of spring. The daffodil is the national flower of Wales and the symbol of cancer tumor charities in many countries. The appearance of the outrageous flowers in springtime is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to a underground storage light. They regrow in the following 12 months 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 expand as tall as 80 cm.
The crops are scapose, having a single central leafless hollow flower stem (scape). Several green or blue-green, narrow, strap-shaped leaves happen from the bulb. The place stem bears a solitary bloom, but occasionally a cluster of plants (umbel). The blooms, that are usually conspicuous and white or yellowish, both or hardly ever inexperienced sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an exterior ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical molded corona. The blooms may hang down (pendent), or be erect. You will discover six pollen bearing stamens surrounding a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The berry includes a dried up capsule that splits (dehisces) releasing numerous black seeds.
The bulb is situated dormant after the leaves and rose stem die back and has contractile root base that pull it down further in to the soil. The blossom leaves and stem form in the light, to emerge the next season. Most varieties are dormant from summer months to overdue winter, flowering in the spring, though a few types are fall months flowering.
