Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common brands including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are 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 flowers are usually white or yellow (orange or green in garden varieties), with either even or contrasting coloured tepals and corona.
Narcissus were well known in ancient civilisation, both and botanically medicinally, but formally referred to by Linnaeus in his Varieties Plantarum (1753). The genus is normally considered to have about ten portions with around 50 species. The true volume of varieties has assorted, depending how they are categorised, scheduled to similarity between species and hybridization. The genus arose some time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact source of the name Narcissus is unknown, but it is linked to a Greek phrase for intoxicated (narcotic) and the misconception of the youngsters of this name who fell deeply in love with his own representation. The English word 'daffodil' is apparently produced from "asphodel", with which it was likened commonly.
The varieties are local to meadows and woods in southern Europe and North Africa with a center of variety in the American Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were released in to the ASIA to the tenth century prior. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are also insect-pollinated. 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 following the 16th hundred years and by the later 19th hundred years were an important commercial crop centred mostly on holland. Today narcissi are popular as trim flowers as ornamental plants in private and public gardens. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering an array of shapes and colours. 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 ingested unintentionally. This property has been exploited for medicinal use in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in books and skill, narcissi are associated with a true number of themes in different cultures, ranging from loss of life to fortune, and as icons of planting season. The daffodil is the countrywide flower of Wales and the mark of tumors charities in many countries. The appearance of the untamed flowers in planting season is associated with festivals 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 calendar year from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf kinds such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might develop as large as 80 cm.
The vegetation are scapose, having a single central leafless hollow rose stem (scape). Several blue-green or green, thin, strap-shaped leaves occur from the light. The place stem usually bears a solitary blossom, but occasionally a cluster of flowers (umbel). The bouquets, which are conspicuous and white or yellowish usually, sometimes both or hardly ever green, 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 flowers may suspend down (pendent), or be erect. You can find six pollen bearing stamens bordering a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The fruit contains a dried out capsule that splits (dehisces) releasing numerous black seeds.
The bulb is situated dormant after the leaves and rose stem die again and has contractile origins that yank it down further in to the soil. The bloom stem and leaves form in the bulb, to emerge the following season. Most species are dormant from summer season to past due winter, flowering in the spring and coil, though a few species are fall flowering.
