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

Narcissus were well known in traditional civilisation, both and botanically medicinally, but formally detailed by Linnaeus in his Types Plantarum (1753). The genus is generally considered to have about ten parts with roughly 50 species. The amount of kinds has mixed, depending about how they are labeled, thanks to similarity between hybridization and varieties. The genus arose time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise origins of the name Narcissus is unfamiliar, but it is often linked to a Greek word for intoxicated (narcotic) and the myth of the youngsters of that name who fell in love with his own representation. The English expression 'daffodil' appears to be produced from "asphodel", with which it was commonly compared.

The kinds are local to meadows and woods in southern Europe and North Africa with a center of variety in the Western Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were introduced into the ASIA to the tenth hundred years 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 increasingly popular in Europe following the 16th century and by the overdue 19th hundred years were an important commercial crop centred generally on holland. Narcissi are popular as lower blooms and as ornamental crops in private and public gardens today. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering an array of colours and shapes. Like other members of their family, narcissi produce a true number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested accidentally. This property has been exploited for medicinal utilization in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in skill and books, narcissi are associated with a true number of themes in several cultures, ranging from loss of life to good fortune, and as icons of spring and coil. The daffodil is the national blossom of Wales and the sign of tumors charities in many countries. The appearance of the wild 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 for an underground storage bulb. They regrow in the following year from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf species such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might expand as tall as 80 cm.

The crops are scapose, having an individual central leafless hollow rose stem (scape). Several green or blue-green, slim, strap-shaped leaves occur from the light bulb. The seed stem bears a solitary bloom, but sometimes a cluster of blossoms (umbel). The blooms, which can be usually conspicuous and white or yellowish, sometimes both or hardly ever inexperienced, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an exterior ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The blossoms may hang up down (pendent), or be erect. You will discover six pollen bearing stamens encircling a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The fruits consists of a dry capsule that splits (dehisces) launching numerous black seeds.

The bulb is placed dormant following the leaves and bloom stem die back and has contractile roots that draw it down further in to the soil. The rose leaves and stem form in the bulb, to emerge the following season. Most types are dormant from summertime to later winter, flowering in the spring, though a few types are fall flowering.
