Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial vegetation 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 members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by way of a cup- or trumpet-shaped corona. The flowers are usually white or yellow (orange or pink in garden varieties), with either standard or contrasting colored corona and tepals.
Narcissus were popular in early civilisation, both and botanically medicinally, but formally referred to by Linnaeus in his Types Plantarum (1753). The genus is generally considered to have about ten parts with roughly 50 species. The true variety of types has varied, depending how they are categorised, scheduled to similarity between kinds and hybridization. The genus arose some right time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact origin of the true name Narcissus is unfamiliar, but it is associated with a Greek phrase for intoxicated (narcotic) and the myth of the young ones of that name who fell in love with his own representation. The English phrase 'daffodil' appears to be produced from "asphodel", with which it was compared commonly.
The species are native to meadows and woods in southern European countries and North Africa with a middle of variety in the American Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were introduced into the Far East before 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 some are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe following the 16th hundred years and by the overdue 19th hundred years were an important commercial crop centred primarily on holland. Narcissi are popular as slice blossoms and as 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 categorized 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 unintentionally. This property has been exploited for medicinal utilization in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in literature and art work, narcissi are associated with a true number of themes in different cultures, ranging from fatality to fortune, and as symbols of springtime. The daffodil is the nationwide bloom of Wales and the icon of cancer charities in many countries. The looks of the wild flowers in planting season is associated with festivals 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 season from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm depending on species. Dwarf varieties such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might grow as high as 80 cm.
The crops are scapose, having an individual central leafless hollow blossom stem (scape). Several blue-green or green, slim, strap-shaped leaves come up from the bulb. The plant stem usually bears a solitary rose, but occasionally a cluster of blossoms (umbel). The flowers, that are conspicuous and white or yellow usually, sometimes both or hardly ever inexperienced, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outside ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The bouquets may suspend down (pendent), or be erect. There are six pollen bearing stamens encircling a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The berries contains a dry out capsule that splits (dehisces) liberating numerous black seeds.
The bulb sits dormant following the leaves and flower stem die again and has contractile roots that pull it down further in to the soil. The bloom stem and leaves form in the light bulb, to emerge the next season. Most types are dormant from summer time to past due winter, flowering in the planting season, though a few kinds are autumn flowering.
