Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial vegetation 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 by a cup- or trumpet-shaped corona. The blossoms are usually white or yellow (orange or red in garden types), with either standard or contrasting coloured corona and tepals.
Narcissus were well known in old civilisation, both and botanically medicinally, but formally explained by Linnaeus in his Types Plantarum (1753). The genus is generally thought to have about ten areas with about 50 species. The number of types has assorted, depending about how they are labeled, due to similarity between hybridization and kinds. The genus arose time 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 anonymous, but it is often associated with a Greek word for intoxicated (narcotic) and the myth of the junior of that name who fell in love with his own reflection. The English phrase 'daffodil' appears to be produced from "asphodel", with which it was likened commonly.
The types are native to meadows and woods in southern European countries and North Africa with a center of variety in the Traditional western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were introduced into the Far East prior to the tenth century. Narcissi tend to be long-lived bulbs, which propagate by division, but are also insect-pollinated. Known pests, diseases and disorders include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have become 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 after the 16th century and by the past due 19th hundred years were an important commercial crop centred primarily on the Netherlands. Today narcissi are popular as trim blossoms and since ornamental plants in private and open public gardens. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering an array of colours and shapes. Like other members with 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 use in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in art and books, narcissi are associated with a true number of themes in several cultures, ranging from loss of life to good fortune, and as symbols of planting season. The daffodil is the countrywide rose of Wales and the sign of cancer tumor charities in many countries. The appearance of the crazy flowers in spring and coil is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to the underground storage light bulb. They regrow in the next yr from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm depending on the species. Dwarf kinds such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might develop as high as 80 cm.
The plant life are scapose, having a single central leafless hollow flower stem (scape). Several blue-green or green, thin, strap-shaped leaves arise from the bulb. The seed stem bears a solitary blossom, but occasionally a cluster of blooms (umbel). The blooms, which can be conspicuous and white or yellowish usually, both or rarely renewable sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outer ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The blossoms may hang up down (pendent), or be erect. There are six pollen bearing stamens bordering a central style. The ovary is second-rate (below the floral parts) consisting of three chambers (trilocular). The fruit includes a dried capsule that splits (dehisces) liberating numerous black seeds.
The bulb is placed dormant after the leaves and flower stem die back again and has contractile roots that draw it down further in to the soil. The bloom stem and leaves form in the light, to emerge the next season. Most species are dormant from summer to overdue winter, flowering in the planting season, though a few types are fall flowering.
