Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common names 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 usually white or yellow (orange or green in garden varieties), with either uniform or contrasting coloured tepals and corona.

Narcissus were popular in old civilisation, both and botanically medicinally, but formally detailed by Linnaeus in his Types Plantarum (1753). The genus is generally considered to have about ten sections with about 50 species. The true range of species has assorted, 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 source of the name Narcissus is mysterious, but it is associated with a Greek word for intoxicated (narcotic) and the misconception of the junior of this name who fell in love with his own representation. The English expression 'daffodil' is apparently derived from "asphodel", with which it was commonly compared.

The kinds are native to meadows and woods in southern Europe and North Africa with a middle of variety in the European Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were created into the Far East to the tenth hundred years 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 tourism and urbanisation.

Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe following the 16th hundred years and by the late 19th century were an important commercial crop centred primarily on the Netherlands. Today narcissi are popular as trim bouquets and since ornamental plants in private and general population gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering a wide range of shapes and colours. Like other members with their family, narcissi create a true 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 resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in artwork and literature, narcissi are associated with a number of themes in various cultures, ranging from loss of life to fortune, and as icons of spring and coil. The daffodil is the nationwide flower of Wales and the icon of tumor charities in many countries. The appearance of the wild flowers in spring is associated with festivals in many places.

Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to a underground storage bulb. They regrow in the following 12 months from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm depending on species. Dwarf species such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might grow as large as 80 cm.

The crops are scapose, having a single central leafless hollow flower stem (scape). Several blue-green or green, narrow, strap-shaped leaves happen from the light. The herb stem usually bears a solitary bloom, but occasionally a cluster of blooms (umbel). The blooms, which can be conspicuous and white or yellowish usually, both or seldom inexperienced sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an exterior ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical molded corona. The plants may suspend down (pendent), or be erect. You can find six pollen bearing stamens adjoining a central style. The ovary is second-rate (below the floral parts) consisting of three chambers (trilocular). The berry includes a dried capsule that splits (dehisces) launching numerous black seeds.

The bulb sits dormant after the leaves and bloom stem die again and has contractile root base that pull it down further in to the soil. The flower leaves and stem form in the bulb, to emerge the following season. Most varieties are dormant from summer season to overdue winter, flowering in the spring, though a few species are fall months flowering.
