Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common labels including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are being used to describe all or some known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted with a cup- or trumpet-shaped corona. The plants are usually white or yellow (orange or pink in garden kinds), with either standard or contrasting coloured corona and tepals.
Narcissus were popular in historical civilisation, both medicinally and botanically, but formally described by Linnaeus in his Species Plantarum (1753). The genus is generally thought to have about ten areas with about 50 species. The amount of varieties has assorted, depending about how they are categorised, thanks 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 areas of southwest Europe. The exact origin of the name Narcissus is unfamiliar, but it is often associated with a Greek term for intoxicated (narcotic) and the misconception of the children of that name who fell in love with his own reflection. The English word 'daffodil' appears to be derived from "asphodel", with which it was commonly likened.
The varieties are local to meadows and woods in southern European countries and North Africa with a center of diversity in the Western Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were created in to the Far East to the tenth hundred years prior. Narcissi tend 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, 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 increasingly popular in Europe following the 16th century and by the later 19th century were an important commercial crop centred primarily on holland. Today narcissi are popular as lower flowers so when ornamental vegetation in private and general public gardens. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering an array of shapes and colours. 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 inadvertently. This property has been exploited for medicinal use within traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in art work and literature, narcissi are associated with a true number of themes in various cultures, ranging from death to good fortune, and as symbols of planting season. The daffodil is the countrywide flower of Wales and the sign of cancer charities in many countries. The appearance of the wild flowers in springtime is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering with an underground storage light. They regrow in the next time from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm depending on the species. Dwarf types such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might expand as large as 80 cm.
The plants are scapose, having a single central leafless hollow bloom stem (scape). Several green or blue-green, small, strap-shaped leaves occur from the light bulb. The flower stem usually bears a solitary rose, but sometimes a cluster of blooms (umbel). The blooms, that are conspicuous and white or yellowish usually, sometimes both or hardly ever renewable, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an exterior ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical shaped corona. The bouquets may suspend down (pendent), or be erect. You can find six pollen bearing stamens encircling a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The berries consists of a dry out capsule that splits (dehisces) releasing numerous black seeds.
The bulb sits dormant after the leaves and rose stem die back again and has contractile roots that take it down further in to the soil. The rose stem and leaves form in the light bulb, to emerge the following season. Most varieties are dormant from summer season to past due winter, flowering in the planting season, though a few types are autumn flowering.
