Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common names 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 with a cup- or trumpet-shaped corona. The plants are generally white or yellowish (orange or pink in garden varieties), with either even or contrasting coloured corona and tepals.

Narcissus were well known in traditional civilisation, both and botanically medicinally, but formally referred to by Linnaeus in his Species Plantarum (1753). The genus is normally considered to have about ten portions with around 50 species. The amount of types has assorted, depending how they are labeled, thanks to similarity between hybridization and types. 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 exact origin of the name Narcissus is anonymous, but it is often associated with a Greek phrase for intoxicated (narcotic) and the misconception of the youngsters of this name who fell in love with his own representation. The English word 'daffodil' appears to be derived from "asphodel", with which it was commonly likened.

The species are native to meadows and woods in southern Europe and North Africa with a centre of diversity in the European Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were unveiled into the Far East to the tenth century prior. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are insect-pollinated also. Known pests, disorders and diseases include viruses, fungi, the larvae of flies, mites and nematodes. 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 after the 16th hundred years and by the overdue 19th hundred years were an important commercial crop centred mainly on the Netherlands. Narcissi are popular as lower plants so when ornamental crops in private and general public gardens today. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a wide range of colours and shapes. Like other members of the 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 use within traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in artwork and literature, narcissi are associated with a true number of themes in several cultures, ranging from fatality to fortune, and as icons of spring. The daffodil is the countrywide bloom of Wales and the sign of cancers charities in many countries. The appearance of the untamed flowers in planting season is associated with festivals in many places.

Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering to a underground storage light bulb. They regrow in the following season from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf varieties such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may expand as tall as 80 cm.

The plants are scapose, having an individual central leafless hollow bloom stem (scape). Several green or blue-green, small, strap-shaped leaves happen from the light. The herb stem usually bears a solitary rose, but sometimes a cluster of blooms (umbel). The flowers, that are conspicuous and white or yellow usually, sometimes both or rarely inexperienced, contain 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 shaped corona. The blooms may suspend down (pendent), or be erect. You will find six pollen bearing stamens encompassing a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The berries includes a dried out capsule that splits (dehisces) liberating numerous black seeds.

The bulb is dormant after the leaves and bloom stem die again and has contractile origins that take it down further in to the soil. The flower leaves and stem form in the light, to emerge the next season. Most varieties are dormant from summertime to later winter, flowering in the spring, though a few kinds are fall flowering.
