Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common names including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are being 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 bouquets are usually white or yellowish (orange or green in garden types), with either uniform or contrasting coloured tepals and corona.

Narcissus were well known in old civilisation, both and botanically medicinally, but formally defined by Linnaeus in his Kinds Plantarum (1753). The genus is normally considered to have about ten areas with around 50 species. The true volume of varieties has assorted, depending on how they are categorized, thanks to similarity between hybridization and species. 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 precise origins of the name Narcissus is anonymous, but it is linked to a Greek word for intoxicated (narcotic) and the misconception of the youth of this name who fell deeply in love with his own reflection. The English term 'daffodil' appears to be produced from "asphodel", with which it was likened commonly.

The varieties are local to meadows and woods in southern European countries and North Africa with a middle of diversity in the Traditional western Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were created in to the Far East to the tenth century 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 tourism and urbanisation.

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 later 19th century were an important commercial crop centred mainly on holland. Today narcissi are popular as trim blooms so that ornamental crops in private and general public gardens. 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 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 artwork and books, narcissi are associated with a true number of themes in various cultures, ranging from loss of life to good fortune, and as icons of spring. The daffodil is the national flower of Wales and the symbol of tumor charities in many countries. The appearance of the wild flowers in planting season is associated with festivals in many places.

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

The plants are scapose, having a single central leafless hollow blossom stem (scape). Several green or blue-green, slim, strap-shaped leaves come up from the light. The plant stem usually bears a solitary rose, but once in a while a cluster of bouquets (umbel). The flowers, which are conspicuous and white or yellowish usually, sometimes both or hardly ever green, contain 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 disc to conical molded corona. The plants may suspend down (pendent), or be erect. You will discover six pollen bearing stamens adjoining a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The fruits consists of a dry capsule that splits (dehisces) launching numerous black seeds.

The bulb lies dormant following the leaves and bloom stem die back again and has contractile roots that yank it down further in to the soil. The rose stem and leaves form in the bulb, to emerge the next season. Most varieties are dormant from summer months to overdue winter, flowering in the spring and coil, though a few species are autumn flowering.
