Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common titles including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are 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 blooms are generally white or yellowish (orange or red in garden kinds), with either standard or contrasting colored corona and tepals.
Narcissus were popular in ancient civilisation, both medicinally and botanically, but formally described by Linnaeus in his Types Plantarum (1753). The genus is generally considered to have about ten portions with about 50 species. The true number of species has assorted, depending on how they are categorized, scheduled to similarity between types 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 exact origins of the real name Narcissus is mysterious, but it is linked to a Greek expression for intoxicated (narcotic) and the misconception of the young ones of that name who fell in love with his own reflection. The English term 'daffodil' is apparently derived from "asphodel", with which it was commonly likened.
The species are indigenous to meadows and woods in southern European countries and North Africa with a centre of diversity in the Traditional western Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were introduced in to 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, nematodes and mites. Some Narcissus species have become extinct, while others are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe after the 16th hundred years and by the overdue 19th hundred years were an important commercial crop centred mainly on holland. Today narcissi are popular as cut plants and since ornamental plants in private and general population gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering a wide range of shapes and colours. Like other members of these 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 use within traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in literature and art work, narcissi are associated with a number of themes in various cultures, ranging from death to fortune, and as icons of spring and coil. The daffodil is the nationwide blossom of Wales and the icon of cancer charities in many countries. The looks of the outdoors flowers in spring and coil is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering for an underground storage light. They regrow in the following 12 months from brown-skinned ovoid light bulbs 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 may increase as high as 80 cm.
The plant life are scapose, having a single central leafless hollow flower stem (scape). Several green or blue-green, small, strap-shaped leaves happen from the light bulb. The herb stem bears a solitary blossom, but sometimes a cluster of bouquets (umbel). The plants, which can be usually conspicuous and white or yellow, both or seldom renewable sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an external ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical molded corona. The flowers may suspend down (pendent), or be erect. You will discover six pollen bearing stamens encircling a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The berries contains a dry out capsule that splits (dehisces) launching numerous black seed products.
The bulb lies dormant following the leaves and flower stem die back again and has contractile root base that pull it down further in to the soil. The rose leaves and stem form in the bulb, to emerge the next season. Most types are dormant from summer months to later winter, flowering in the springtime, though a few species are fall months flowering.
