Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common brands 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 by way of a cup- or trumpet-shaped corona. The bouquets are generally white or yellowish (orange or red in garden kinds), with either standard or contrasting coloured corona and tepals.
Narcissus were popular in old civilisation, both and botanically medicinally, but formally identified by Linnaeus in his Varieties Plantarum (1753). The genus is normally considered to have about ten sections with around 50 species. The amount of varieties has varied, depending how they are classified, a consequence of to similarity between hybridization and varieties. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise origins of the name Narcissus is undiscovered, but it is often associated with a Greek expression for intoxicated (narcotic) and the myth of the children 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 native to meadows and woods in southern European countries and North Africa with a middle of variety in the American Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were introduced into the Far East prior to 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, mites and nematodes. Some Narcissus species have grown to be extinct, while some are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the initial times, but became ever more popular in Europe following the 16th century and by the later 19th century were an important commercial crop centred mostly on the Netherlands. Today narcissi are popular as slash plants so when ornamental vegetation in private and general population gardens. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering an array 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 accidentally. This property has been exploited for medicinal use within traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in art work and books, narcissi are associated with a true number of themes in various cultures, ranging from loss of life to good fortune, and as icons of spring and coil. The daffodil is the countrywide bloom of Wales and the sign of tumors charities in many countries. The looks of the outrageous flowers in planting season 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 bulb. They regrow in the following 12 months from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm with respect to the species. Dwarf species such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might develop as high as 80 cm.
The crops are scapose, having an individual central leafless hollow rose stem (scape). Several blue-green or green, slim, strap-shaped leaves happen from the light. The herb stem usually bears a solitary flower, but occasionally a cluster of flowers (umbel). The flowers, which are usually conspicuous and white or yellowish, both or seldom renewable sometimes, contain 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 disc to conical formed corona. The bouquets may hang up down (pendent), or be erect. You will discover six pollen bearing stamens encircling a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The fruit includes a dried up capsule that splits (dehisces) launching numerous black seeds.
The bulb lays dormant following the leaves and flower stem die again and has contractile root base that yank it down further into the soil. The bloom leaves and stem form in the light bulb, to emerge the next season. Most varieties are dormant from summer to past due winter, flowering in the spring and coil, though a few kinds are fall flowering.
