Signification de la couleur de la fleur de Narcisse

Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial vegetation 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 by way of a cup- or trumpet-shaped corona. The blossoms are generally white or yellow (orange or red in garden kinds), with either even or contrasting colored tepals and corona.

Narcissus were well known in historical civilisation, both medicinally and botanically, but formally defined by Linnaeus in his Varieties Plantarum (1753). The genus is normally considered to have about ten areas with roughly 50 species. The true range of species has varied, depending how they are categorised, anticipated to similarity between species and hybridization. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise origin of the name Narcissus is unidentified, but it is associated with a Greek term for intoxicated (narcotic) and the myth of the young ones of this name who fell in love with his own representation. The English word 'daffodil' is apparently produced from "asphodel", with which it was compared commonly.

The types are indigenous to meadows and woods in southern European countries and North Africa with a middle of diversity in the European Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were introduced into 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 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 later 19th hundred years were an important commercial crop centred mostly on the Netherlands. Today narcissi are popular as slice plants and as ornamental crops in private and general public gardens. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering an array of shapes and colours. Like other members of the family, narcissi produce 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 utilization in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in literature and art, narcissi are associated with a true number of themes in different cultures, ranging from death to fortune, and as icons of planting season. The daffodil is the countrywide rose of Wales and the sign of tumor charities in many countries. The looks of the wild flowers in springtime is associated with celebrations in many places.

Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to a underground storage light. They regrow in the next season from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm depending on the species. Dwarf kinds such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might grow as high as 80 cm.

The plant life are scapose, having a single central leafless hollow bloom stem (scape). Several green or blue-green, slim, strap-shaped leaves happen from the light bulb. The plant stem bears a solitary blossom, but occasionally a cluster of blossoms (umbel). The blossoms, which are usually conspicuous and white or yellowish, both or seldom green sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outside ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical shaped corona. The flowers may suspend down (pendent), or be erect. You will find six pollen bearing stamens bordering a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The berries involves a dry out capsule that splits (dehisces) liberating numerous black seeds.

The bulb is placed dormant after the leaves and rose stem die back again and has contractile origins that draw it down further into the soil. The flower stem and leaves form in the light, to emerge the following season. Most varieties are dormant from warmer summer months to later winter, flowering in the spring, though a few kinds are autumn flowering.
