Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common names 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 way of a cup- or trumpet-shaped corona. The bouquets are usually white or yellow (orange or pink in garden kinds), with either standard or contrasting coloured tepals and corona.
Narcissus were well known in old civilisation, both and botanically medicinally, but formally described by Linnaeus in his Kinds Plantarum (1753). The genus is normally thought to have about ten parts with about 50 species. The number of kinds has mixed, depending how they are categorised, credited to similarity between varieties and hybridization. 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 origin of the name Narcissus is unidentified, but it is linked to a Greek term for intoxicated (narcotic) and the myth of the children of this name who fell in love with his own reflection. The English word 'daffodil' is apparently derived from "asphodel", with which it was commonly compared.
The kinds are local to meadows and woods in southern Europe and North Africa with a centre 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 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, 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 ever more popular in Europe following the 16th hundred years and by the late 19th hundred years were an important commercial crop centred mainly on the Netherlands. Narcissi are popular as slash bouquets as ornamental vegetation in private and general population gardens today. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering an array of shapes and colours. Like other members of their family, narcissi create a number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested inadvertently. This property has been exploited for medicinal use within traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in books and art work, narcissi are associated with a number of themes in different cultures, ranging from loss of life to good fortune, and as icons of springtime. The daffodil is the countrywide flower of Wales and the icon of cancers charities in many countries. The appearance 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 with an underground storage light. They regrow in the next calendar year from brown-skinned ovoid 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 elevation of 5-8 cm, while Narcissus tazetta might develop as extra tall as 80 cm.
The vegetation are scapose, having an individual central leafless hollow blossom stem (scape). Several blue-green or green, slim, strap-shaped leaves come up from the light. The place stem usually bears a solitary bloom, but once in a while a cluster of bouquets (umbel). The plants, that happen to be conspicuous and white or yellow usually, both or rarely renewable sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outer ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical shaped corona. The flowers may hang up down (pendent), or be erect. You can find six pollen bearing stamens surrounding a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The fruit includes a dried up capsule that splits (dehisces) launching numerous black seeds.
The bulb lays dormant following the leaves and flower stem die back again and has contractile roots that take it down further in to the soil. The flower stem and leaves form in the bulb, to emerge the following season. Most species are dormant from summer to overdue winter, flowering in the spring and coil, though a few varieties are fall months flowering.
