Narcissus Jonquilla Narcissus jonquilla

Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plant life 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 with a cup- or trumpet-shaped corona. The plants are generally white or yellow (orange or red in garden varieties), with either even or contrasting colored tepals and corona.

Narcissus were popular in historical civilisation, both medicinally and botanically, but formally detailed by Linnaeus in his Kinds Plantarum (1753). The genus is generally thought to have about ten sections with around 50 species. The number of types has varied, depending on how they are classified, credited to similarity between varieties and hybridization. The genus arose some time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise origin of the true name Narcissus is anonymous, but it is often linked to a Greek word for intoxicated (narcotic) and the myth of the junior of that name who fell in love with his own representation. The English phrase 'daffodil' appears to be derived from "asphodel", with which it was compared commonly.

The kinds are indigenous to meadows and woods in southern European countries and North Africa with a center of variety in the American 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 also insect-pollinated. Known pests, diseases and disorders include viruses, fungi, the larvae of flies, nematodes and mites. Some Narcissus species have grown to be extinct, while some 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 past due 19th century were an important commercial crop centred generally on holland. Today narcissi are popular as cut flowers and since ornamental plants in private and public gardens. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering an array of shapes and colours. 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 used in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in books and artwork, narcissi are associated with a true number of themes in several cultures, ranging from death to fortune, and as icons of spring. The daffodil is the nationwide rose of Wales and the sign of cancer tumor charities in many countries. The appearance of the outrageous flowers in spring is associated with festivals in many places.

Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to a underground storage light bulb. They regrow in the following 12 months from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf kinds such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might increase as extra tall as 80 cm.

The plant life are scapose, having an individual central leafless hollow flower stem (scape). Several blue-green or green, small, strap-shaped leaves occur from the bulb. The vegetable stem usually bears a solitary flower, but occasionally a cluster of flowers (umbel). The blooms, which can be conspicuous and white or yellow usually, both or seldom renewable sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outer ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical shaped corona. The blooms may hang up down (pendent), or be erect. There are six pollen bearing stamens encircling a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The berries contains a dried capsule that splits (dehisces) liberating numerous black seeds.

The bulb is situated dormant following the leaves and blossom stem die back and has contractile origins that take it down further into the soil. The bloom leaves and stem form in the bulb, to emerge the next season. Most types are dormant from warmer summer months to past due winter, flowering in the spring, though a few kinds are fall flowering.
