Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common names including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are being used to describe all or some members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted with a cup- or trumpet-shaped corona. The blooms are usually white or yellowish (orange or red in garden types), with either uniform or contrasting coloured tepals and corona.
Narcissus were well known in historic civilisation, both medicinally and botanically, but formally identified by Linnaeus in his Varieties Plantarum (1753). The genus is generally considered to have about ten sections with approximately 50 species. The true variety of kinds has assorted, depending on how they are labeled, anticipated to similarity between kinds 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 precise origins of the real name Narcissus is anonymous, but it is linked to a Greek phrase for intoxicated (narcotic) and the myth of the young ones of this name who fell in love with his own representation. The English phrase 'daffodil' is apparently derived from "asphodel", with which it was likened commonly.
The types are indigenous to meadows and woods in southern Europe and North Africa with a center of variety in the American Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were launched into the Far East to the tenth century 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 ever more popular in Europe following the 16th century and by the overdue 19th century were an important commercial crop centred generally on holland. Narcissi are popular as slice bouquets and as ornamental plants in private and general public gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering a wide range of colours and shapes. Like other members with 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 resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in books and skill, narcissi are associated with a number of themes in different cultures, ranging from fatality to good fortune, and as symbols of springtime. The daffodil is the countrywide bloom of Wales and the image of tumors charities in many countries. The appearance of the crazy flowers in spring is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to the underground storage light bulb. They regrow in the following year from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm with respect to the species. Dwarf kinds such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may expand as high 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 light. The place stem bears a solitary bloom, but occasionally a cluster of plants (umbel). The bouquets, which can be usually conspicuous and white or yellowish, sometimes both or rarely renewable, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an exterior ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical formed corona. The bouquets may hang 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 berries involves a dry out capsule that splits (dehisces) liberating numerous black seeds.
The bulb is dormant after the leaves and flower stem die back again and has contractile root base that draw it down further in to the soil. The bloom leaves and stem form in the light bulb, to emerge the next season. Most species are dormant from summer to past due winter, flowering in the spring and coil, though a few varieties are autumn flowering.
