Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plant life 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 usually white or yellow (orange or red in garden kinds), with either uniform or contrasting colored tepals and corona.

Narcissus were popular in old civilisation, both and botanically medicinally, but formally referred to by Linnaeus in his Kinds Plantarum (1753). The genus is generally thought to have about ten areas with about 50 species. The number of varieties has assorted, depending on how they are classified, due to similarity between hybridization and species. The genus arose some right amount of time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The exact source of the name Narcissus is undiscovered, but it is often linked to a Greek phrase for intoxicated (narcotic) and the myth of the children of that name who fell deeply in love with his own reflection. The English expression 'daffodil' appears to be produced from "asphodel", with which it was commonly likened.

The varieties are indigenous to meadows and woods in southern Europe and North Africa with a centre of variety in the American Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were created in to 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, 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 initial times, but became ever more popular in Europe after the 16th century and by the later 19th century were an important commercial crop centred primarily on holland. Today narcissi are popular as trim flowers and as ornamental crops in private and general population gardens. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are categorised 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 accidentally. This property has been exploited for medicinal use in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in books and art, narcissi are associated with a number of themes in several cultures, ranging from fatality to fortune, and as icons of spring and coil. The daffodil is the countrywide flower of Wales and the sign of tumor charities in many countries. The looks of the crazy flowers in spring and coil is associated with festivals in many places.

Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering with an underground storage light bulb. They regrow in the following yr from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm depending on species. Dwarf kinds such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might develop as high as 80 cm.

The crops are scapose, having a single central leafless hollow flower stem (scape). Several green or blue-green, narrow, strap-shaped leaves come up from the bulb. The plant stem bears a solitary blossom, but once in a while a cluster of blossoms (umbel). The bouquets, which can be conspicuous and white or yellowish usually, sometimes both or seldom renewable, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an exterior ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical molded corona. The flowers may suspend down (pendent), or be erect. You will find six pollen bearing stamens bordering a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The super fruit consists of a dried capsule that splits (dehisces) liberating numerous black seed products.

The bulb sits dormant following the leaves and rose stem die back and has contractile origins that draw it down further into the soil. The bloom leaves and stem form in the bulb, to emerge the next season. Most types are dormant from summertime to late winter, flowering in the springtime, though a few types are fall months flowering.
