Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common brands including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are 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 flowers are usually white or yellowish (orange or green in garden kinds), with either standard or contrasting coloured corona and tepals.
Narcissus were popular in early civilisation, both and botanically medicinally, but formally detailed by Linnaeus in his Kinds Plantarum (1753). The genus is generally considered to have about ten sections with about 50 species. The true amount of types has varied, depending on how they are grouped, 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 areas of southwest Europe. The exact origin of the name Narcissus is anonymous, but it is often associated with a Greek expression for intoxicated (narcotic) and the misconception of the youth of that name who fell deeply in love with his own representation. The English phrase 'daffodil' appears to be derived from "asphodel", with which it was commonly likened.
The varieties are native to meadows and woods in southern Europe and North Africa with a center of diversity in the European Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were introduced in to the ASIA to the tenth hundred years prior. 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, 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 increasingly popular in Europe following the 16th century and by the late 19th century were an important commercial crop centred primarily on the Netherlands. Today narcissi are popular as slice flowers so that as ornamental plants in private and public gardens. The long history of breeding has led to thousands 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 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 treating Alzheimer's dementia. Long celebrated in books and artwork, narcissi are associated with a number of themes in several cultures, ranging from loss of life to good fortune, and as symbols of spring. The daffodil is the countrywide blossom of Wales and the image of cancer charities in many countries. The appearance of the wild flowers in spring is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering to an underground storage light. They regrow in the following season from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm depending on species. Dwarf species such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might develop as high as 80 cm.
The crops are scapose, having a single central leafless hollow flower stem (scape). Several blue-green or green, thin, strap-shaped leaves occur from the bulb. The flower stem usually bears a solitary blossom, but once in a while a cluster of plants (umbel). The bouquets, which can be conspicuous and white or yellow usually, both or almost never inexperienced sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an exterior ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical shaped corona. The blooms may hang up down (pendent), or be erect. There are six pollen bearing stamens encompassing a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The super fruit consists of a dry out capsule that splits (dehisces) launching numerous black seed products.
The bulb sits dormant after the leaves and rose stem die again and has contractile roots that yank it down further in to the soil. The blossom stem and leaves form in the light, to emerge the next season. Most species are dormant from summer time to late winter, flowering in the spring and coil, though a few types are fall months flowering.
