Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common brands including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are being used to describe all or some known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by way of a cup- or trumpet-shaped corona. The plants are usually white or yellow (orange or red in garden types), with either even or contrasting colored tepals and corona.
Narcissus were well known in ancient civilisation, both and botanically medicinally, but formally referred to by Linnaeus in his Species Plantarum (1753). The genus is normally considered to have about ten parts with approximately 50 species. The true quantity of species has mixed, depending how they are grouped, a consequence of 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 origins of the true name Narcissus is anonymous, but it is linked to a Greek phrase for intoxicated (narcotic) and the myth of the children of this name who fell in love with his own reflection. The English word 'daffodil' appears to be derived from "asphodel", with which it was compared commonly.
The types are native to meadows and woods in southern Europe and North Africa with a centre of diversity in the Western Mediterranean, the Iberian peninsula particularly. 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, 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 increasingly popular in Europe following the 16th hundred years and by the overdue 19th hundred years were an important commercial crop centred mainly on holland. Narcissi are popular as chop bouquets so that as ornamental plants in private and public gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering a variety of shapes and colours. Like other members with their family, narcissi create 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 use within traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in literature and fine art, narcissi are associated with a number of themes in various cultures, ranging from fatality to fortune, and as symbols of springtime. The daffodil is the national blossom of Wales and the sign of cancer tumor charities in many countries. The appearance of the wild flowers in springtime is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering with an underground storage light. They regrow in the following calendar year from brown-skinned ovoid bulbs with pronounced necks, and reach levels of 5-80 cm depending on the species. Dwarf species such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might increase as tall as 80 cm.
The plant life are scapose, having a single central leafless hollow rose stem (scape). Several green or blue-green, small, strap-shaped leaves come up from the light bulb. The vegetable stem bears a solitary rose, but occasionally a cluster of plants (umbel). The bouquets, that happen to be usually conspicuous and white or yellow, sometimes both or almost never green, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outside ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical molded corona. The blooms may hang down (pendent), or be erect. You will discover six pollen bearing stamens adjoining a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The super fruit involves a dried capsule that splits (dehisces) releasing numerous black seeds.
The bulb is placed dormant following the leaves and flower stem die back again and has contractile origins that draw it down further into the soil. The blossom leaves and stem form in the light bulb, to emerge the next season. Most species are dormant from summertime to late winter, flowering in the spring, though a few species are fall months flowering.
