Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial crops 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 by the cup- or trumpet-shaped corona. The flowers are generally white or yellow (orange or green in garden varieties), with either uniform or contrasting coloured corona and tepals.

Narcissus were well known in historic civilisation, both and botanically medicinally, but formally defined by Linnaeus in his Types Plantarum (1753). The genus is normally considered to have about ten parts with approximately 50 species. The true range of varieties has varied, depending how they are classified, anticipated to similarity between kinds and hybridization. The genus arose some right time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise origin of the name Narcissus is unknown, but it is often associated with a Greek expression for intoxicated (narcotic) and the myth of the youngsters of this name who fell deeply in love with his own representation. The English phrase 'daffodil' appears to be produced from "asphodel", with which it was commonly compared.

The species are native 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 century 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, mites and nematodes. 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 after the 16th hundred years and by the past due 19th hundred years were an important commercial crop centred primarily on holland. Today narcissi are popular as slice blossoms as ornamental plant life in private and public gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering an array of shapes and colours. Like other members of these family, narcissi produce a number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested inadvertently. This property has been exploited for medicinal use within traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in art and literature, narcissi are associated with a true number of themes in different cultures, ranging from loss of life to fortune, and as symbols of spring and coil. The daffodil is the national blossom of Wales and the sign of cancers charities in many countries. The looks of the outdoors flowers in planting season is associated with festivals in many places.

Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering for an underground storage light bulb. They regrow in the next year 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 height of 5-8 cm, while Narcissus tazetta might increase as tall as 80 cm.

The vegetation are scapose, having a single central leafless hollow bloom stem (scape). Several green or blue-green, slim, strap-shaped leaves happen from the light. The vegetable stem bears a solitary rose, but once in a while a cluster of blossoms (umbel). The flowers, that happen to be usually conspicuous and white or yellow, sometimes both or hardly ever inexperienced, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outer ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The blossoms may suspend down (pendent), or be erect. There are six pollen bearing stamens encompassing a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The fruits contains a dry capsule that splits (dehisces) liberating numerous black seeds.

The bulb is dormant following the leaves and flower stem die again and has contractile root base that take it down further in to the soil. The bloom leaves and stem form in the bulb, to emerge the following season. Most kinds are dormant from summer season to overdue winter, flowering in the spring, though a few kinds are autumn flowering.
