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 by a cup- or trumpet-shaped corona. The flowers are usually white or yellowish (orange or red in garden varieties), with either uniform or contrasting colored tepals and corona.
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 considered to have about ten sections with about 50 species. The true range of varieties has varied, depending on how they are classified, thanks to similarity between hybridization and kinds. 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 real name Narcissus is unfamiliar, but it is often linked to a Greek expression for intoxicated (narcotic) and the myth of the youngsters of that name who fell in love with his own representation. The English term 'daffodil' is apparently derived from "asphodel", with which it was commonly compared.
The varieties are local to meadows and woods in southern Europe and North Africa with a center of diversity in the American Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were introduced in to the Far East prior to the tenth century. Narcissi tend 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 become extinct, while some are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the initial 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 mainly on the Netherlands. Today narcissi are popular as lower flowers as ornamental vegetation in private and general public gardens. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering an array of colours and shapes. Like other members of the family, narcissi create 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 utilization in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in skill and literature, narcissi are associated with a true number of themes in several cultures, ranging from loss of life to good fortune, and as icons of spring and coil. The daffodil is the national bloom of Wales and the image of tumor charities in many countries. The looks of the wild flowers in springtime is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering with an underground storage light. They regrow in the following season from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm with respect to the species. Dwarf types such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may grow as high as 80 cm.
The vegetation are scapose, having an individual central leafless hollow rose stem (scape). Several blue-green or green, narrow, strap-shaped leaves happen from the bulb. The vegetable stem usually bears a solitary rose, but sometimes a cluster of flowers (umbel). The plants, which can be conspicuous and white or yellowish usually, both or rarely renewable sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an external ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical designed corona. The blossoms may hang down (pendent), or be erect. You can find six pollen bearing stamens adjoining a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The super fruit contains a dried up capsule that splits (dehisces) launching numerous black seeds.
The bulb is dormant after the leaves and bloom stem die back and has contractile root base that yank it down further into the soil. The rose leaves and stem form in the light, to emerge the next season. Most species are dormant from summertime to overdue winter, flowering in the spring and coil, though a few varieties are fall months flowering.
