Narcissus Sir Winston Churchill, Landscape Size

Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common names including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are used to describe all or some known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by a cup- or trumpet-shaped corona. The bouquets are usually white or yellowish (orange or red in garden kinds), with either standard or contrasting coloured tepals and corona.

Narcissus were well known in historic civilisation, both and botanically medicinally, but formally described by Linnaeus in his Varieties Plantarum (1753). The genus is generally thought to have about ten sections with about 50 species. The number of types has varied, depending on how they are grouped, as a consequence to similarity between hybridization and kinds. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact origin of the true name Narcissus is unfamiliar, but it is associated with a Greek word for intoxicated (narcotic) and the misconception of the youth 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 commonly compared.

The kinds are native to meadows and woods in southern European countries and North Africa with a center of diversity in the European Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were presented in to the Far East to the tenth hundred years 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 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 following the 16th hundred years and by the later 19th century were an important commercial crop centred mainly on holland. Today narcissi are popular as cut plants and as 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 grouped into divisions, covering a wide range 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 use in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in literature and fine art, narcissi are associated with a true number of themes in different cultures, ranging from fatality to fortune, and as icons of springtime. The daffodil is the national rose of Wales and the sign of tumor charities in many countries. The looks of the outrageous flowers in springtime is associated with festivals in many places.

Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to a underground storage light bulb. They regrow in the next year from brown-skinned ovoid light bulbs 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 grow as high as 80 cm.

The vegetation are scapose, having a single central leafless hollow blossom stem (scape). Several green or blue-green, slim, strap-shaped leaves come up from the light bulb. The flower stem bears a solitary blossom, but occasionally a cluster of plants (umbel). The blooms, which can be conspicuous and white or yellow usually, sometimes both or rarely renewable, 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 molded corona. The flowers may hang up down (pendent), or be erect. You will discover six pollen bearing stamens surrounding a central style. The ovary is substandard (below the floral parts) consisting of three chambers (trilocular). The berries contains a dry out capsule that splits (dehisces) launching numerous black seed products.

The bulb lays dormant after the leaves and blossom stem die again and has contractile origins that move it down further in to the soil. The blossom leaves and stem form in the light bulb, to emerge the next season. Most varieties are dormant from warmer summer months to past due winter, flowering in the spring and coil, though a few types are fall flowering.
