Description Jonquilla daffodil narcissus var stratosphere 2.jpg

Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common titles 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 flowers are usually white or yellowish (orange or green in garden kinds), with either uniform or contrasting colored tepals and corona.

Narcissus were well known in early civilisation, both medicinally and botanically, but formally explained by Linnaeus in his Varieties Plantarum (1753). The genus is generally thought to have about ten areas with about 50 species. The true volume of kinds has mixed, depending about how they are categorised, thanks to similarity between hybridization and varieties. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise source of the name Narcissus is unidentified, but it is often associated with a Greek phrase for intoxicated (narcotic) and the misconception of the children of that name who fell in love with his own representation. The English phrase 'daffodil' is apparently produced from "asphodel", with which it was commonly likened.

The types 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 created into the ASIA to the tenth hundred years prior. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are insect-pollinated also. Known pests, disorders and diseases include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have grown to be 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 hundred years and by the later 19th hundred years were an important commercial crop centred generally on the Netherlands. Narcissi are popular as slash plants and since ornamental crops in private and open public gardens today. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering a wide range of colours and shapes. Like other members of these 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 literature and skill, narcissi are associated with a true number of themes in different cultures, ranging from loss of life to fortune, and as symbols of springtime. The daffodil is the nationwide rose of Wales and the image of tumor charities in many countries. The appearance of the outdoors flowers in planting season 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 bulb. They regrow in the following yr from brown-skinned ovoid bulbs with pronounced necks, and reach levels of 5-80 cm with respect to the species. Dwarf species such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might increase as high as 80 cm.

The crops are scapose, having an individual central leafless hollow rose stem (scape). Several green or blue-green, narrow, strap-shaped leaves happen from the light. The seed stem usually bears a solitary blossom, but once in a while a cluster of flowers (umbel). The bouquets, which are conspicuous and white or yellowish usually, sometimes both or rarely inexperienced, consist of 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. You will find six pollen bearing stamens bordering a central style. The ovary is second-rate (below the floral parts) consisting of three chambers (trilocular). The super fruit includes a dried up capsule that splits (dehisces) releasing numerous black seeds.

The bulb is placed dormant after the leaves and rose stem die back and has contractile root base that move it down further in to the soil. The rose leaves and stem form in the light, to emerge the next season. Most species are dormant from summer season to past due winter, flowering in the spring, though a few kinds are fall flowering.
