Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial crops 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 members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted with a cup- or trumpet-shaped corona. The blooms are generally white or yellowish (orange or green in garden types), with either uniform or contrasting coloured corona and tepals.
Narcissus were well known in early civilisation, both and botanically medicinally, but formally detailed by Linnaeus in his Species Plantarum (1753). The genus is normally considered to have about ten parts with around 50 species. The amount of kinds has mixed, depending about how they are categorised, thanks to similarity between hybridization and varieties. The genus arose some time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact source of the real name Narcissus is unknown, but it is associated with a Greek phrase for intoxicated (narcotic) and the myth of the youth of that name who fell in love with his own reflection. The English phrase 'daffodil' appears to be derived from "asphodel", with which it was commonly compared.
The varieties are local to meadows and woods in southern European countries and North Africa with a middle of diversity in the American Mediterranean, the Iberian peninsula particularly. 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, 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 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 overdue 19th century were an important commercial crop centred generally on the Netherlands. Narcissi are popular as chop plants so that ornamental crops in private and public gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering a wide range of colours and shapes. Like other members of their family, narcissi produce 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 utilization in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in literature and skill, narcissi are associated with a number of themes in various cultures, ranging from fatality to fortune, and as symbols of planting season. The daffodil is the nationwide rose of Wales and the symbol of cancer charities in many countries. The appearance of the crazy flowers in springtime is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to an underground storage light bulb. They regrow in the next season from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm with respect to the species. Dwarf varieties such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might grow as extra tall as 80 cm.
The vegetation are scapose, having a single central leafless hollow bloom stem (scape). Several green or blue-green, small, strap-shaped leaves happen from the light bulb. The place stem bears a solitary blossom, but sometimes a cluster of bouquets (umbel). The plants, which are usually conspicuous and white or yellow, sometimes both or rarely green, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an exterior ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The blooms may suspend down (pendent), or be erect. You will discover six pollen bearing stamens surrounding a central style. The ovary is substandard (below the floral parts) consisting of three chambers (trilocular). The berries contains a dried capsule that splits (dehisces) liberating numerous black seeds.
The bulb sits dormant following the leaves and rose stem die again and has contractile origins that pull it down further into the soil. The bloom stem and leaves form in the bulb, to emerge the next season. Most varieties are dormant from summer to past due winter, flowering in the spring and coil, though a few kinds are autumn flowering.
