Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common labels 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 the cup- or trumpet-shaped corona. The bouquets are generally white or yellow (orange or red in garden types), with either even or contrasting coloured corona and tepals.
Narcissus were popular in early civilisation, both medicinally and botanically, but formally described by Linnaeus in his Species Plantarum (1753). The genus is generally thought to have about ten portions with approximately 50 species. The true quantity of kinds has assorted, depending on how they are categorised, thanks to similarity between hybridization and species. The genus arose some right 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 unknown, but it is linked to a Greek term for intoxicated (narcotic) and the myth of the youngsters of this name who fell deeply in love with his own reflection. The English term 'daffodil' is apparently produced from "asphodel", with which it was commonly compared.
The varieties are indigenous 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 presented in to the Far East to the tenth hundred years prior. Narcissi tend to be long-lived bulbs, which propagate by division, but are also insect-pollinated. Known pests, diseases and disorders include viruses, fungi, the larvae of flies, nematodes and mites. Some Narcissus species have grown to be extinct, while some are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the initial times, but became ever more popular in Europe after the 16th hundred years and by the past due 19th century were an important commercial crop centred primarily on the Netherlands. Narcissi are popular as trim blooms and as ornamental vegetation in private and public gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a wide range of shapes and colours. Like other members of their family, narcissi produce 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 used in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in artwork and literature, narcissi are associated with a true number of themes in various cultures, ranging from fatality to fortune, and as symbols of springtime. The daffodil is the nationwide rose of Wales and the symbol of malignancy 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 a underground storage bulb. They regrow in the next year from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf types such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might expand as large as 80 cm.
The crops are scapose, having an individual central leafless hollow bloom stem (scape). Several blue-green or green, narrow, strap-shaped leaves arise from the bulb. The plant stem bears a solitary flower, but once in a while a cluster of flowers (umbel). The bouquets, which are conspicuous and white or yellowish usually, both or almost never inexperienced sometimes, contain 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 designed corona. The bouquets may hang down (pendent), or be erect. You can find six pollen bearing stamens adjoining a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The berry consists of a dry capsule that splits (dehisces) launching numerous black seeds.
The bulb lies dormant following the leaves and rose stem die again and has contractile roots that yank it down further in to the soil. The flower stem and leaves form in the light bulb, to emerge the next season. Most kinds are dormant from summer to later winter, flowering in the planting season, though a few kinds are autumn flowering.
