Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common titles including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are being used to describe all or some known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by way of a cup- or trumpet-shaped corona. The bouquets are generally white or yellowish (orange or red in garden varieties), with either even or contrasting colored corona and tepals.

Narcissus were well known in historic civilisation, both medicinally and botanically, but formally explained by Linnaeus in his Kinds Plantarum (1753). The genus is generally thought to have about ten areas with roughly 50 species. The true amount of kinds has assorted, depending about how they are classified, thanks to similarity between hybridization and varieties. 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 origins of the name Narcissus is anonymous, but it is linked to a Greek expression for intoxicated (narcotic) and the myth of the youth of that name who fell in love with his own reflection. The English expression 'daffodil' is apparently derived from "asphodel", with which it was compared commonly.

The species are local 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 also insect-pollinated. Known pests, diseases and disorders 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 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 the Netherlands. Narcissi are popular as slice plants and since ornamental vegetation in private and general population gardens today. The long history of breeding has led to thousands 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 produce 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 utilization in traditional healing and has led to 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 various cultures, ranging from death to fortune, and as icons of spring and coil. The daffodil is the national bloom of Wales and the image of tumors charities in many countries. The appearance of the untamed flowers in planting season is associated with celebrations in many places.

Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering with an underground storage bulb. They regrow in the following 12 months from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm with respect to the species. Dwarf species such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may increase as extra tall as 80 cm.

The plants are scapose, having an individual central leafless hollow bloom stem (scape). Several blue-green or green, small, strap-shaped leaves occur from the light. The place stem usually bears a solitary rose, but occasionally a cluster of blooms (umbel). The blossoms, which are usually conspicuous and white or yellowish, sometimes both or almost never renewable, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outside ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The plants may hang up down (pendent), or be erect. You can find six pollen bearing stamens adjoining a central style. The ovary is substandard (below the floral parts) consisting of three chambers (trilocular). The super fruit contains 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 roots that take it down further in to the soil. The flower stem and leaves form in the bulb, to emerge the following season. Most kinds are dormant from summer months to later winter, flowering in the spring and coil, though a few types are fall flowering.
