Narcissus Sun Disc

Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common names 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 plants are generally white or yellow (orange or pink in garden kinds), with either uniform or contrasting coloured corona and tepals.

Narcissus were well known in historical civilisation, both and botanically medicinally, but formally explained by Linnaeus in his Species Plantarum (1753). The genus is generally considered to have about ten areas with roughly 50 species. The true range of varieties has varied, depending on how they are categorised, thanks to similarity between hybridization and species. The genus arose some right time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise source of the name Narcissus is mysterious, but it is often linked to a Greek expression for intoxicated (narcotic) and the myth of the youth of that name who fell deeply in love with his own reflection. The English expression '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 middle of diversity 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, 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 tourism and urbanisation.

Historical accounts suggest narcissi have been cultivated from the initial times, but became ever more popular in Europe following the 16th hundred years and by the late 19th century were an important commercial crop centred mainly on the Netherlands. Narcissi are popular as cut blooms so that ornamental plants in private and open public gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering a variety of shapes and colours. Like other members of the family, narcissi create a true number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested accidentally. This property has been exploited for medicinal utilization in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in books and artwork, narcissi are associated with a true number of themes in different cultures, ranging from fatality to good fortune, and as symbols of spring. The daffodil is the countrywide blossom of Wales and the icon of tumors charities in many countries. The looks of the wild flowers in spring is associated with festivals in many places.

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

The crops are scapose, having a single central leafless hollow blossom stem (scape). Several green or blue-green, thin, strap-shaped leaves occur from the light. The plant stem bears a solitary blossom, but occasionally a cluster of blossoms (umbel). The blooms, which are usually conspicuous and white or yellowish, sometimes both or almost never renewable, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outside ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The plants may suspend down (pendent), or be erect. You can find six pollen bearing stamens adjoining a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The fruit includes a dried up capsule that splits (dehisces) liberating numerous black seed products.

The bulb is situated dormant following the leaves and blossom stem die again and has contractile origins that yank it down further in to the soil. The blossom stem and leaves form in the bulb, to emerge the next season. Most varieties are dormant from summer to later winter, flowering in the planting season, though a few species are autumn flowering.
