Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial vegetation 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 members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by way of a cup- or trumpet-shaped corona. The bouquets are usually white or yellowish (orange or green in garden varieties), with either even or contrasting colored corona and tepals.
Narcissus were popular in historical civilisation, both medicinally and botanically, but formally detailed by Linnaeus in his Varieties Plantarum (1753). The genus is generally considered to have about ten portions with approximately 50 species. The true quantity of types has varied, depending about how they are categorized, thanks to similarity between hybridization and varieties. The genus arose some right amount of time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise source of the true name Narcissus is unknown, but it is often associated with a Greek expression for intoxicated (narcotic) and the myth of the young ones of that name who fell in love with his own representation. The English term 'daffodil' appears to be derived from "asphodel", with which it was commonly likened.
The kinds are native to meadows and woods in southern Europe and North Africa with a center of diversity in the European Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were launched into the Far East 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, diseases and disorders include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have become extinct, while some are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe after the 16th century and by the later 19th hundred years were an important commercial crop centred primarily on holland. Today narcissi are popular as chop plants so when ornamental plants in private and open public gardens. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a wide range of shapes and colours. Like other members with their 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 use within traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in books and art work, narcissi are associated with a number of themes in several cultures, ranging from fatality to fortune, and as symbols of springtime. The daffodil is the national rose of Wales and the symbol of cancer tumor charities in many countries. The looks of the outdoors flowers in spring and coil is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to an underground storage bulb. They regrow in the next yr from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm with regards to the species. Dwarf varieties such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might increase as extra tall as 80 cm.
The vegetation are scapose, having a single central leafless hollow bloom stem (scape). Several green or blue-green, slim, strap-shaped leaves happen from the light bulb. The flower stem usually bears a solitary blossom, but occasionally a cluster of flowers (umbel). The blossoms, which can be usually conspicuous and white or yellow, sometimes both or hardly ever renewable, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an external ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical formed corona. The bouquets may suspend down (pendent), or be erect. You will discover six pollen bearing stamens encompassing a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The super fruit involves a dried out capsule that splits (dehisces) releasing numerous black seed products.
The bulb lays dormant after the leaves and blossom stem die back again and has contractile roots that yank it down further into the soil. The rose stem and leaves form in the light, to emerge the following season. Most types are dormant from summer season to later winter, flowering in the spring and coil, though a few varieties are autumn flowering.
