Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial crops 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 a cup- or trumpet-shaped corona. The blossoms are generally white or yellow (orange or green in garden varieties), with either even or contrasting colored corona and tepals.
Narcissus were popular in historical civilisation, both and botanically medicinally, but formally explained by Linnaeus in his Types Plantarum (1753). The genus is generally thought to have about ten areas with around 50 species. The true volume of types has varied, depending about how they are classified, thanks to similarity between hybridization and species. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact origin of the name Narcissus is undiscovered, but it is linked to a Greek word for intoxicated (narcotic) and the misconception of the children of that name who fell deeply in love with his own reflection. The English word 'daffodil' is apparently produced from "asphodel", with which it was likened commonly.
The species are local to meadows and woods in southern European countries and North Africa with a middle of diversity in the Western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were introduced into 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 grown to be extinct, while some are threatened by increasing urbanisation and tourism.
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 overdue 19th century were an important commercial crop centred mostly on the Netherlands. Today narcissi are popular as lower blooms and since ornamental plants in private and public gardens. The long history of breeding has resulted in 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 create 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 treating Alzheimer's dementia. Long celebrated in literature and skill, narcissi are associated with a true number of themes in different cultures, ranging from death to good fortune, and as icons of spring. The daffodil is the national bloom of Wales and the image of tumor charities in many countries. The appearance of the outdoors flowers in spring and coil is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering to an underground storage light bulb. They regrow in the next time from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm depending on the species. Dwarf species such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may expand as large as 80 cm.
The plants are scapose, having a single central leafless hollow bloom stem (scape). Several green or blue-green, small, strap-shaped leaves come up from the bulb. The seed stem usually bears a solitary flower, but sometimes a cluster of bouquets (umbel). The bouquets, which can be usually conspicuous and white or yellowish, sometimes both or hardly ever green, contain 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 disc to conical designed corona. The bouquets may suspend down (pendent), or be erect. A couple of six pollen bearing stamens adjoining a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The fruit contains a dry capsule that splits (dehisces) launching numerous black seeds.
The bulb is placed dormant following the leaves and flower stem die back and has contractile roots that pull it down further into the soil. The rose stem and leaves form in the light, to emerge the next season. Most types are dormant from warmer summer months to later winter, flowering in the planting season, though a few species are fall months flowering.
