Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common labels including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are used to describe all or some 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 red in garden varieties), with either even or contrasting coloured corona and tepals.
Narcissus were well known in old civilisation, both and botanically medicinally, but formally identified by Linnaeus in his Varieties Plantarum (1753). The genus is normally thought to have about ten sections with approximately 50 species. The amount of kinds has varied, depending about how they are categorised, due 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 areas of southwest Europe. The precise origins of the true name Narcissus is unknown, but it is linked to a Greek phrase for intoxicated (narcotic) and the misconception of the junior of this name who fell deeply in love with his own reflection. The English phrase 'daffodil' appears to be produced from "asphodel", with which it was likened commonly.
The types are local to meadows and woods in southern Europe and North Africa with a center of diversity in the Western Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were introduced into the Far East before the tenth century. Narcissi have a tendency 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, mites and nematodes. Some Narcissus species have grown to be extinct, while others 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 following the 16th century and by the late 19th hundred years were an important commercial crop centred mostly on the Netherlands. Today narcissi are popular as lower flowers as ornamental vegetation in private and general 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 an array of shapes and colours. Like other members with 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 literature and art work, narcissi are associated with a number of themes in different cultures, ranging from fatality to good fortune, and as symbols of planting season. The daffodil is the countrywide rose of Wales and the icon of cancers charities in many countries. The looks of the outrageous flowers in spring is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering for an underground storage light. They regrow in the following season from brown-skinned ovoid bulbs with pronounced necks, and reach levels of 5-80 cm depending on the species. Dwarf kinds such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might grow as tall as 80 cm.
The plant life are scapose, having a single central leafless hollow flower stem (scape). Several blue-green or green, slim, strap-shaped leaves come up from the bulb. The place stem bears a solitary blossom, but once in a while a cluster of blooms (umbel). The plants, which can be conspicuous and white or yellowish usually, both or rarely renewable sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outer ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The blooms may suspend down (pendent), or be erect. There are six pollen bearing stamens adjoining a central style. The ovary is substandard (below the floral parts) consisting of three chambers (trilocular). The fruit contains a dry capsule that splits (dehisces) liberating numerous black seeds.
The bulb lays dormant following the leaves and blossom stem die again and has contractile origins that pull it down further into the soil. The blossom leaves and stem form in the light, to emerge the next season. Most varieties are dormant from warmer summer months to past due winter, flowering in the springtime, though a few types are autumn flowering.
