Narcissus /n?:r's?s?s/ is a genus of predominantly 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 the cup- or trumpet-shaped corona. The flowers are usually white or yellowish (orange or green in garden varieties), with either even or contrasting colored corona and tepals.

Narcissus were popular in historical civilisation, both medicinally and botanically, but formally explained by Linnaeus in his Types Plantarum (1753). The genus is normally thought to have about ten sections with roughly 50 species. The number of kinds has mixed, depending about how they are labeled, scheduled to similarity between types and hybridization. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise origins of the true name Narcissus is unknown, but it is associated with a Greek word for intoxicated (narcotic) and the misconception of the youngsters of that name who fell in love with his own reflection. The English expression 'daffodil' appears to be produced from "asphodel", with which it was compared commonly.

The species are native 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 introduced into the Far East before the tenth century. Narcissi tend 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 tourism and urbanisation.

Historical accounts suggest narcissi have been cultivated from the earliest times, but became ever more popular in Europe after the 16th century and by the late 19th century were an important commercial crop centred primarily on holland. Narcissi are popular as lower bouquets and as ornamental vegetation 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 a wide range of shapes and colours. Like other members of these family, narcissi produce a true 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 use within traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in books and fine art, narcissi are associated with a number of themes in various cultures, ranging from loss of life to good fortune, and as symbols of planting season. The daffodil is the nationwide flower of Wales and the sign of cancer tumor charities in many countries. The appearance of the crazy flowers in planting season is associated with festivals in many places.

Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering to an underground storage light bulb. They regrow in the following year from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf types such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might develop as large as 80 cm.

The plants are scapose, having a single central leafless hollow bloom stem (scape). Several blue-green or green, thin, strap-shaped leaves occur from the bulb. The plant stem bears a solitary blossom, but sometimes a cluster of bouquets (umbel). The blooms, which are usually conspicuous and white or yellowish, sometimes both or hardly ever green, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube 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 hang down (pendent), or be erect. You can find six pollen bearing stamens surrounding a central style. The ovary is substandard (below the floral parts) consisting of three chambers (trilocular). The fruits includes a dry out capsule that splits (dehisces) launching numerous black seeds.

The bulb lays dormant following the leaves and bloom stem die again and has contractile root base that pull it down further into the soil. The rose leaves and stem form in the light, to emerge the next season. Most types are dormant from summer season to overdue winter, flowering in the springtime, though a few varieties are autumn flowering.
