Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial crops 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 a cup- or trumpet-shaped corona. The flowers are usually white or yellow (orange or green in garden varieties), with either standard or contrasting coloured corona and tepals.
Narcissus were well known in old civilisation, both and botanically medicinally, but formally explained by Linnaeus in his Types Plantarum (1753). The genus is generally thought to have about ten portions with approximately 50 species. The number of kinds has mixed, depending how they are classified, as a consequence to similarity between hybridization and types. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise origin of the name Narcissus is unknown, but it is linked to a Greek phrase for intoxicated (narcotic) and the myth of the young ones of that name who fell deeply in love with his own reflection. The English term 'daffodil' appears to be derived from "asphodel", with which it was commonly compared.
The kinds are local to meadows and woods in southern European countries and North Africa with a centre of variety in the Western Mediterranean, the Iberian peninsula particularly. Both cultivated and wild 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, diseases and disorders include viruses, fungi, the larvae of flies, nematodes and mites. 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 past due 19th hundred years were an important commercial crop centred mostly on the Netherlands. Today narcissi are popular as cut blooms and as ornamental vegetation in private and open 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 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 utilization in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in art work and literature, narcissi are associated with a true number of themes in several cultures, ranging from death to good fortune, and as icons of planting season. The daffodil is the countrywide bloom of Wales and the mark of malignancy charities in many countries. The looks 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 season from brown-skinned ovoid lights 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 grow as tall as 80 cm.
The crops are scapose, having an individual central leafless hollow rose stem (scape). Several green or blue-green, slim, strap-shaped leaves happen from the light bulb. The plant stem usually bears a solitary blossom, but once in a while a cluster of bouquets (umbel). The bouquets, that happen to be conspicuous and white or yellow usually, both or almost never inexperienced sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an exterior ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical shaped corona. The plants may hang up down (pendent), or be erect. You will discover six pollen bearing stamens adjoining a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The berries involves a dried capsule that splits (dehisces) launching numerous black seeds.
The bulb is situated dormant after the leaves and bloom stem die back again and has contractile root base that take it down further into the soil. The blossom stem and leaves form in the light bulb, to emerge the following season. Most kinds are dormant from summer time to overdue winter, flowering in the spring, though a few types are autumn flowering.
