Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common brands 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 blossoms are usually white or yellow (orange or red in garden types), with either uniform or contrasting coloured corona and tepals.
Narcissus were well known in historical civilisation, both medicinally and botanically, but formally detailed by Linnaeus in his Species Plantarum (1753). The genus is generally considered to have about ten areas with about 50 species. The number of kinds has assorted, depending how they are categorised, scheduled to similarity between kinds and hybridization. The genus arose some right time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise origin of the name Narcissus is mysterious, but it is associated with a Greek expression for intoxicated (narcotic) and the myth of the children of that name who fell in love with his own representation. The English word 'daffodil' appears to be produced from "asphodel", with which it was commonly compared.
The species are local to meadows and woods in southern European countries and North Africa with a centre of variety in the American Mediterranean, particularly the Iberian peninsula. 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 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 others are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became ever more popular in Europe following the 16th century and by the later 19th hundred years were an important commercial crop centred primarily on the Netherlands. Narcissi are popular as slash blossoms and as ornamental vegetation in private and general public gardens today. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering a wide range of colours and shapes. Like other members with their family, narcissi create 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 used in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in literature and art work, narcissi are associated with a number of themes in various cultures, ranging from death to good fortune, and as icons of spring and coil. The daffodil is the national flower of Wales and the mark of tumor charities in many countries. The appearance of the untamed flowers in springtime is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to an underground storage bulb. They regrow in the following season from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf types such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might develop as high as 80 cm.
The plant life are scapose, having an individual central leafless hollow flower stem (scape). Several blue-green or green, thin, strap-shaped leaves happen from the light. The seed stem bears a solitary blossom, but occasionally a cluster of plants (umbel). The blossoms, which can be conspicuous and white or yellowish usually, sometimes both or rarely inexperienced, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outside ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical shaped corona. The plants may hang down (pendent), or be erect. You can find six pollen bearing stamens encircling a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The fruits consists of a dried capsule that splits (dehisces) launching numerous black seeds.
The bulb is dormant after the leaves and bloom stem die again and has contractile roots that take it down further in to the soil. The bloom stem and leaves form in the light, to emerge the next season. Most types are dormant from summertime to late winter, flowering in the planting season, though a few varieties are fall months flowering.
