Narcissus triandrus EngelstränenNarzisse

Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial crops 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 a cup- or trumpet-shaped corona. The plants are usually white or yellow (orange or pink in garden kinds), with either standard or contrasting colored tepals and corona.

Narcissus were popular in old civilisation, both medicinally and botanically, but formally defined by Linnaeus in his Species Plantarum (1753). The genus is normally considered to have about ten sections with roughly 50 species. The true number of types has mixed, depending on how they are categorized, a consequence of to similarity between hybridization and species. The genus arose time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise source of the true name Narcissus is anonymous, but it is associated with a Greek phrase for intoxicated (narcotic) and the myth of the youngsters of this name who fell in love with his own reflection. The English phrase 'daffodil' appears to be derived from "asphodel", with which it was compared commonly.

The species are local to meadows and woods in southern Europe and North Africa with a centre of variety in the European Mediterranean, the Iberian peninsula particularly. Both wild and cultivated 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 insect-pollinated also. Known pests, disorders and diseases include viruses, fungi, the larvae of flies, nematodes and mites. Some Narcissus species have become extinct, while others are threatened by increasing urbanisation and tourism.

Historical accounts suggest narcissi have been cultivated from the initial times, but became ever more popular in Europe following the 16th century and by the overdue 19th hundred years were an important commercial crop centred generally on the Netherlands. Narcissi are popular as trim blooms so when ornamental plant life in private and general population gardens today. The long history of breeding has led to 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 produce 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 within traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in literature and art work, narcissi are associated with a true number of themes in several cultures, ranging from loss of life to fortune, and as icons of spring and coil. The daffodil is the countrywide blossom of Wales and the image of cancers charities in many countries. The looks of the untamed flowers in springtime 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. They regrow in the following calendar year from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm with respect to the species. Dwarf species such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may grow as large as 80 cm.

The plant life are scapose, having a single central leafless hollow bloom stem (scape). Several blue-green or green, thin, strap-shaped leaves come up from the light bulb. The seed stem bears a solitary flower, but once in a while a cluster of bouquets (umbel). The blossoms, that are conspicuous and white or yellowish 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 exterior ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical molded corona. The blooms may hang up down (pendent), or be erect. A couple of six pollen bearing stamens encircling a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The berry involves a dry capsule that splits (dehisces) liberating numerous black seed products.

The bulb is situated dormant after the leaves and blossom stem die back and has contractile roots that move it down further in to the soil. The flower leaves and stem form in the bulb, to emerge the next season. Most kinds are dormant from summer months to overdue winter, flowering in the springtime, though a few types are fall months flowering.
