Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common titles 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 plants are generally white or yellow (orange or green in garden types), with either even or contrasting coloured corona and tepals.

Narcissus were popular in ancient civilisation, both medicinally and botanically, but formally detailed by Linnaeus in his Species Plantarum (1753). The genus is normally considered to have about ten areas with approximately 50 species. The amount of kinds has assorted, depending about how they are labeled, credited to similarity between species 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 unfamiliar, but it is often associated with a Greek term for intoxicated (narcotic) and the misconception of the children of this name who fell deeply in love with his own representation. The English term 'daffodil' is apparently derived from "asphodel", with which it was likened commonly.

The kinds are local to meadows and woods in southern European countries and North Africa with a middle of variety in the European Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were introduced in to the Far East before the tenth century. Narcissi have a tendency 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 others are threatened by increasing urbanisation and tourism.

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 mainly on the Netherlands. Narcissi are popular as chop flowers as ornamental plant life in private and general public gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering an array of colours and shapes. Like other members of their 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 use in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in artwork and literature, narcissi are associated with a true number of themes in several cultures, ranging from fatality to fortune, and as symbols of springtime. The daffodil is the national flower of Wales and the mark of cancer tumor charities in many countries. The appearance of the wild 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 a underground storage light bulb. They regrow in the following time from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm with respect to the species. Dwarf types such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might expand as tall 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 occur from the light. The seed stem usually bears a solitary flower, but sometimes a cluster of blossoms (umbel). The flowers, which are conspicuous and white or yellow usually, sometimes both or seldom inexperienced, contain 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 molded corona. The plants may hang down (pendent), or be erect. You will discover six pollen bearing stamens surrounding a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The fruits involves a dry capsule that splits (dehisces) liberating numerous black seed products.

The bulb is situated dormant following the leaves and blossom stem die again and has contractile root base that draw it down further into the soil. The blossom leaves and stem form in the bulb, to emerge the following season. Most varieties are dormant from summer months to later winter, flowering in the springtime, though a few species are fall flowering.
