Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common labels 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 way of a cup- or trumpet-shaped corona. The blooms are generally white or yellowish (orange or red in garden kinds), with either uniform or contrasting coloured corona and tepals.

Narcissus were popular in traditional civilisation, both medicinally and botanically, but formally identified by Linnaeus in his Types Plantarum (1753). The genus is generally thought to have about ten portions with around 50 species. The number of types has assorted, depending about how they are categorised, scheduled to similarity between varieties and hybridization. The genus arose some right amount of time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact origins of the true name Narcissus is undiscovered, but it is often linked to a Greek word for intoxicated (narcotic) and the myth of the youth of this name who fell in love with his own reflection. The English term 'daffodil' appears to be derived from "asphodel", with which it was commonly likened.

The varieties are local to meadows and woods in southern European countries and North Africa with a centre of diversity in the Western Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were released in to 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, diseases and disorders 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 initial times, but became increasingly popular in Europe following the 16th century and by the past due 19th hundred years were an important commercial crop centred generally on holland. Narcissi are popular as slice blooms so that as ornamental plants in private and general population gardens today. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering an array of colours and shapes. Like other members of these family, narcissi create 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 used in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in artwork and literature, narcissi are associated with a number of themes in various cultures, ranging from fatality to good fortune, and as icons of springtime. The daffodil is the national bloom of Wales and the icon of tumor charities in many countries. The looks of the outrageous flowers in spring and coil is associated with celebrations in many places.

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

The plant life are scapose, having a single central leafless hollow bloom stem (scape). Several green or blue-green, slim, strap-shaped leaves occur from the light. The vegetable stem bears a solitary flower, but sometimes a cluster of blossoms (umbel). The blossoms, that are conspicuous and white or yellowish usually, both or almost never green sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outside ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The bouquets may suspend down (pendent), or be erect. You will find six pollen bearing stamens adjoining a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The fruits includes a dried up capsule that splits (dehisces) launching numerous black seed products.

The bulb lies dormant following the leaves and flower stem die again and has contractile origins that take it down further in to the soil. The bloom stem and leaves form in the light, to emerge the following season. Most kinds are dormant from summer months to late winter, flowering in the springtime, though a few species are autumn flowering.
