Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plant life 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 with a cup- or trumpet-shaped corona. The flowers are generally white or yellowish (orange or green in garden types), with either even or contrasting colored tepals and corona.
Narcissus were popular in traditional civilisation, both medicinally and botanically, but formally detailed by Linnaeus in his Species Plantarum (1753). The genus is generally considered to have about ten areas with around 50 species. The true amount of types has varied, depending how they are grouped, credited to similarity between varieties and hybridization. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact source of the name Narcissus is unknown, but it is often linked to a Greek term for intoxicated (narcotic) and the myth of the youngsters of this name who fell deeply in love with his own reflection. The English expression 'daffodil' is apparently derived from "asphodel", with which it was likened commonly.
The kinds are local to meadows and woods in southern Europe and North Africa with a center of diversity in the Western Mediterranean, particularly the Iberian peninsula. Both wild and cultivated 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 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 tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became ever more popular in Europe following the 16th hundred years and by the past due 19th hundred years were an important commercial crop centred primarily on holland. Narcissi are popular as lower blossoms as ornamental plants in private and general public gardens today. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a wide range 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 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 books and art, narcissi are associated with a true number of themes in several cultures, ranging from fatality to good fortune, and as icons of spring and coil. The daffodil is the nationwide blossom of Wales and the image of cancer tumor charities in many countries. The looks of the crazy 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 light bulb. They regrow in the next time from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm with respect to the species. Dwarf types such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might expand as extra tall as 80 cm.
The crops are scapose, having an individual central leafless hollow blossom stem (scape). Several blue-green or green, narrow, strap-shaped leaves occur from the bulb. The herb stem bears a solitary rose, but sometimes a cluster of plants (umbel). The blooms, that are conspicuous and white or yellow usually, sometimes both or rarely renewable, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outer ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical molded corona. The blooms may hang up down (pendent), or be erect. You will find six pollen bearing stamens encircling a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The super fruit contains a dried out capsule that splits (dehisces) liberating numerous black seed products.
The bulb sits dormant following the leaves and rose stem die back again and has contractile origins that move it down further in to the soil. The rose leaves and stem form in the light bulb, to emerge the next season. Most types are dormant from summer season to past due winter, flowering in the spring, though a few varieties are fall months flowering.
