Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial crops 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 bouquets are usually white or yellowish (orange or pink in garden varieties), with either even or contrasting colored corona and tepals.
Narcissus were well known in traditional civilisation, both and botanically medicinally, but formally defined by Linnaeus in his Species Plantarum (1753). The genus is normally thought to have about ten sections with approximately 50 species. The amount of species has varied, depending how they are grouped, due to similarity between species and hybridization. The genus arose some right amount of time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The exact source of the true name Narcissus is undiscovered, but it is associated with 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 phrase 'daffodil' appears to be derived from "asphodel", with which it was likened commonly.
The species are native to meadows and woods in southern Europe and North Africa with a center of diversity in the American Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were launched into the Far East to the tenth century prior. Narcissi tend 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 initial times, but became ever more popular in Europe following the 16th century and by the later 19th century were an important commercial crop centred mainly on the Netherlands. Today narcissi are popular as trim blossoms and since ornamental vegetation in private and general population gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering an array of shapes and colours. 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 ingested inadvertently. This property has been exploited for medicinal used in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in books and artwork, narcissi are associated with a true number of themes in different cultures, ranging from fatality to fortune, and as icons of spring. The daffodil is the national bloom of Wales and the image 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 a underground storage bulb. They regrow in the next season from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm depending on species. Dwarf kinds such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might grow as extra tall as 80 cm.
The crops are scapose, having a single central leafless hollow blossom stem (scape). Several green or blue-green, thin, strap-shaped leaves occur from the light. The flower stem usually bears a solitary blossom, but once in a while a cluster of blossoms (umbel). The bouquets, which are usually conspicuous and white or yellow, both or almost never inexperienced sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an exterior ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical designed corona. The blossoms may hang down (pendent), or be erect. You can find six pollen bearing stamens encircling a central style. The ovary is substandard (below the floral parts) consisting of three chambers (trilocular). The berries consists of a dry out capsule that splits (dehisces) launching numerous black seed products.
The bulb lies dormant after the leaves and rose stem die back and has contractile roots that yank it down further in to the soil. The rose leaves and stem form in the bulb, to emerge the following season. Most types are dormant from summer season to late winter, flowering in the planting season, though a few species are fall months flowering.
