Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common labels 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 way of a cup- or trumpet-shaped corona. The plants are usually white or yellow (orange or red in garden varieties), with either standard or contrasting colored corona and tepals.
Narcissus were well known in early civilisation, both and botanically medicinally, but formally referred to by Linnaeus in his Kinds Plantarum (1753). The genus is generally thought to have about ten portions with approximately 50 species. The amount of kinds has mixed, depending how they are categorised, a consequence of to similarity between hybridization and varieties. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The exact source of the true name Narcissus is unidentified, but it is associated with a Greek phrase for intoxicated (narcotic) and the myth of the young ones of this name who fell in love with his own representation. The English phrase 'daffodil' is apparently derived from "asphodel", with which it was likened commonly.
The species are indigenous to meadows and woods in southern Europe and North Africa with a middle of variety in the European 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 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, nematodes and mites. 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 increasingly popular in Europe following the 16th century and by the past due 19th hundred years were an important commercial crop centred mainly on holland. Today narcissi are popular as chop flowers so when ornamental plant life in private and open public gardens. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering a variety of shapes and colours. Like other members of these family, narcissi produce a 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 utilization in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in art work and literature, narcissi are associated with a true number of themes in several cultures, ranging from loss of life to fortune, and as icons of springtime. The daffodil is the nationwide flower of Wales and the sign of malignancy charities in many countries. The looks of the untamed flowers in spring is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to an underground storage light. They regrow in the following time from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm with regards to the species. Dwarf species such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may develop as tall as 80 cm.
The plant life are scapose, having an individual central leafless hollow rose stem (scape). Several green or blue-green, small, strap-shaped leaves come up from the bulb. The place stem usually bears a solitary bloom, but once in a while a cluster of bouquets (umbel). The bouquets, that happen to be conspicuous and white or yellowish usually, both or rarely green sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an external ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical molded corona. The flowers may hang down (pendent), or be erect. You can find six pollen bearing stamens surrounding a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The fruit consists of a dry capsule that splits (dehisces) releasing numerous black seeds.
The bulb is situated dormant after the leaves and blossom stem die back and has contractile roots that yank it down further into the soil. The blossom stem and leaves form in the bulb, to emerge the next season. Most types are dormant from warmer summer months to late winter, flowering in the spring, though a few species are autumn flowering.
