Narcissus viridiflorus Flower

Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plants 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 the cup- or trumpet-shaped corona. The blooms are usually white or yellowish (orange or pink in garden varieties), with either even or contrasting coloured corona and tepals.

Narcissus were popular in early civilisation, both medicinally and botanically, but formally detailed by Linnaeus in his Varieties Plantarum (1753). The genus is normally thought to have about ten areas with around 50 species. The true number of species has mixed, depending on how they are categorised, anticipated to similarity between kinds 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 exact origins of the true name Narcissus is undiscovered, but it is associated with a Greek phrase for intoxicated (narcotic) and the misconception of the junior of this name who fell in love with his own reflection. The English word 'daffodil' appears to be produced from "asphodel", with which it was compared commonly.

The varieties are native to meadows and woods in southern European countries and North Africa with a center of variety in the American 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, 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 tourism and urbanisation.

Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe after the 16th hundred years and by the later 19th hundred years were an important commercial crop centred primarily on holland. Narcissi are popular as cut flowers and as ornamental crops in private and open public gardens today. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a wide range of colours and shapes. Like other members of these family, narcissi produce a number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested unintentionally. This property has been exploited for medicinal utilization in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in art and literature, narcissi are associated with a number of themes in various cultures, ranging from loss of life to fortune, and as icons of spring and coil. The daffodil is the countrywide bloom of Wales and the symbol of cancer tumor charities in many countries. The looks of the crazy flowers in spring and coil 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 bulb. They regrow in the following time 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 might develop as extra tall as 80 cm.

The plant life are scapose, having an individual central leafless hollow bloom stem (scape). Several green or blue-green, small, strap-shaped leaves arise from the light. The herb stem bears a solitary bloom, but occasionally a cluster of plants (umbel). The flowers, which can be conspicuous and white or yellowish usually, both or hardly ever inexperienced sometimes, 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 disk to conical formed corona. The blooms may hang up down (pendent), or be erect. You can find six pollen bearing stamens encompassing a central style. The ovary is inferior (below the floral parts) consisting of three chambers (trilocular). The fruits contains a dried up capsule that splits (dehisces) liberating numerous black seed products.

The bulb lies dormant following the leaves and bloom stem die back again and has contractile root base that draw it down further in to the soil. The bloom stem and leaves form in the light, to emerge the following season. Most species are dormant from summertime to later winter, flowering in the planting season, though a few kinds are autumn flowering.
