Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common labels 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 plants are usually white or yellowish (orange or red in garden varieties), with either uniform or contrasting coloured corona and tepals.

Narcissus were well known in ancient civilisation, both medicinally and botanically, but formally detailed by Linnaeus in his Varieties Plantarum (1753). The genus is normally thought to have about ten parts with roughly 50 species. The true quantity of types has varied, depending about how they are labeled, due to similarity between hybridization and kinds. 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 true name Narcissus is unknown, but it is often linked to a Greek expression for intoxicated (narcotic) and the misconception of the youth of that name who fell deeply in love with his own representation. The English term 'daffodil' appears to be derived from "asphodel", with which it was likened commonly.

The types are indigenous to meadows and woods in southern Europe and North Africa with a center of variety in the American Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were introduced into the ASIA to the tenth hundred years prior. Narcissi tend 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 grown to be extinct, while others 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 following the 16th century and by the late 19th century were an important commercial crop centred mostly on holland. Narcissi are popular as slice blooms and since ornamental vegetation in private and general public gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering an array of shapes and colours. 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 ingested unintentionally. This property has been exploited for medicinal used in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in books and art work, narcissi are associated with a number of themes in several cultures, ranging from loss of life to good fortune, and as icons of springtime. The daffodil is the nationwide rose of Wales and the image of malignancy charities in many countries. The appearance of the untamed flowers in spring is associated with celebrations in many places.

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

The vegetation are scapose, having a single central leafless hollow rose stem (scape). Several blue-green or green, thin, strap-shaped leaves happen from the light. The flower stem usually bears a solitary blossom, but sometimes a cluster of plants (umbel). The bouquets, which are usually conspicuous and white or yellow, both or seldom renewable sometimes, 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 disc to conical designed corona. The blossoms may suspend down (pendent), or be erect. You will discover six pollen bearing stamens bordering a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The berries consists of a dry out capsule that splits (dehisces) releasing numerous black seed products.

The bulb is placed dormant following the leaves and flower stem die back and has contractile roots that pull 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 summer to later winter, flowering in the spring, though a few varieties are fall months flowering.
