Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plants 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 known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by a cup- or trumpet-shaped corona. The blooms are usually white or yellowish (orange or red in garden kinds), with either even or contrasting coloured tepals and corona.
Narcissus were well known in old civilisation, both and botanically medicinally, but formally described by Linnaeus in his Types Plantarum (1753). The genus is generally considered to have about ten sections with around 50 species. The true variety of varieties has mixed, depending on how they are classified, credited to similarity between kinds 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 precise origins of the name Narcissus is unidentified, but it is often associated with a Greek phrase for intoxicated (narcotic) and the misconception of the junior of that name who fell in love with his own reflection. The English expression 'daffodil' is apparently produced from "asphodel", with which it was commonly likened.
The species are indigenous to meadows and woods in southern Europe and North Africa with a centre of diversity in the Traditional western Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were introduced in to the Far East before the tenth century. 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, mites and nematodes. Some Narcissus species have become extinct, while others are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became ever more popular in Europe following the 16th hundred years and by the later 19th century were an important commercial crop centred mainly on the Netherlands. Today narcissi are popular as lower flowers as ornamental vegetation 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 a wide range of colours and shapes. Like other members of their 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 within traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in artwork and books, narcissi are associated with a true number of themes in different 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 tumors charities in many countries. The appearance of the crazy flowers in planting season 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 bulb. They regrow in the following time from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf varieties such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might increase as extra tall as 80 cm.
The crops are scapose, having a single central leafless hollow rose stem (scape). Several blue-green or green, narrow, strap-shaped leaves arise from the bulb. The flower stem usually bears a solitary flower, but occasionally a cluster of blooms (umbel). The bouquets, which can be conspicuous and white or yellow usually, sometimes both or rarely renewable, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an exterior ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical shaped corona. The bouquets may hang down (pendent), or be erect. You will find six pollen bearing stamens bordering a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The fruit contains a dried capsule that splits (dehisces) launching numerous black seed products.
The bulb is dormant after the leaves and bloom stem die back again and has contractile roots that take it down further into the soil. The blossom leaves and stem form in the light, to emerge the next season. Most types are dormant from summertime to overdue winter, flowering in the spring, though a few kinds are autumn flowering.
