Description Narcissus.jpg

Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common titles 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 way of a cup- or trumpet-shaped corona. The plants are generally white or yellowish (orange or green in garden kinds), with either even or contrasting colored tepals and corona.

Narcissus were well known in early civilisation, both medicinally and botanically, but formally referred to by Linnaeus in his Varieties Plantarum (1753). The genus is normally considered to have about ten sections with approximately 50 species. The number of types has assorted, depending how they are categorized, due to similarity between varieties and hybridization. The genus arose time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The exact origin of the name Narcissus is undiscovered, but it is often linked to a Greek phrase for intoxicated (narcotic) and the myth of the young ones of that name who fell in love with his own representation. The English term 'daffodil' appears to be produced from "asphodel", with which it was commonly compared.

The kinds are native to meadows and woods in southern European countries and North Africa with a centre of diversity in the European Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were created into the ASIA to the tenth century prior. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are insect-pollinated also. Known pests, diseases and disorders include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have become extinct, while some 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 past due 19th century were an important commercial crop centred mainly on holland. Today narcissi are popular as slash blossoms as ornamental plant life in private and general population gardens. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering a wide range 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 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 death to good fortune, and as icons of spring. The daffodil is the countrywide flower of Wales and the image of tumors charities in many countries. The appearance of the crazy flowers in planting season is associated with celebrations in many places.

Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering for an underground storage bulb. They regrow in the following 12 months from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf species such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may develop as large as 80 cm.

The vegetation are scapose, having an individual central leafless hollow rose stem (scape). Several blue-green or green, slim, strap-shaped leaves arise from the light. The plant stem usually bears a solitary flower, but occasionally a cluster of bouquets (umbel). The bouquets, that are conspicuous and white or yellow usually, sometimes both or seldom inexperienced, 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 blooms may hang up down (pendent), or be erect. A couple of six pollen bearing stamens encompassing a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The berry includes a dried capsule that splits (dehisces) liberating numerous black seeds.

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