Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial vegetation 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 a cup- or trumpet-shaped corona. The plants are generally white or yellowish (orange or pink in garden types), with either standard or contrasting colored corona and tepals.

Narcissus were well known in traditional civilisation, both and botanically medicinally, but formally described by Linnaeus in his Kinds Plantarum (1753). The genus is generally considered to have about ten portions with roughly 50 species. The amount of varieties has varied, depending how they are grouped, scheduled to similarity between kinds and hybridization. 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 exact source of the name Narcissus is unidentified, but it is often associated with a Greek word for intoxicated (narcotic) and the myth of the children of that name who fell in love with his own representation. The English phrase 'daffodil' appears to be produced from "asphodel", with which it was compared commonly.

The varieties are local 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 ASIA to the tenth hundred years prior. Narcissi tend to be long-lived bulbs, which propagate by division, but are insect-pollinated also. 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 urbanisation and tourism.

Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe after the 16th century and by the late 19th century were an important commercial crop centred generally on holland. Today narcissi are popular as slash flowers and since ornamental crops in private and public gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering a variety of colours and shapes. Like other members with their family, narcissi create a true number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested inadvertently. 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 art work and literature, narcissi are associated with a number of themes in several cultures, ranging from loss of life to good fortune, and as symbols of spring. The daffodil is the countrywide blossom of Wales and the mark of malignancy charities in many countries. The looks of the crazy flowers in springtime is associated with celebrations in many places.

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

The vegetation are scapose, having an individual central leafless hollow bloom stem (scape). Several green or blue-green, small, strap-shaped leaves come up from the light bulb. The flower stem bears a solitary bloom, but sometimes a cluster of bouquets (umbel). The flowers, that happen to be conspicuous and white or yellowish usually, sometimes both or almost never inexperienced, contain 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 disc to conical formed corona. The flowers may hang down (pendent), or be erect. You will find six pollen bearing stamens encircling a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The super fruit includes a dry out capsule that splits (dehisces) launching numerous black seeds.

The bulb is placed dormant after the leaves and rose stem die again and has contractile roots that pull it down further into the soil. The blossom leaves and stem form in the bulb, to emerge the next season. Most kinds are dormant from summer to overdue winter, flowering in the springtime, though a few types are autumn flowering.
