Narcissus /n?:r's?s?s/ is a genus of mostly 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 by way of a cup- or trumpet-shaped corona. The plants are generally white or yellow (orange or green in garden types), with either even or contrasting colored corona and tepals.
Narcissus were well known in historical civilisation, both and botanically medicinally, but formally defined by Linnaeus in his Varieties Plantarum (1753). The genus is generally thought to have about ten areas with approximately 50 species. The amount of types has assorted, depending about how they are categorized, scheduled to similarity between kinds and hybridization. The genus arose some right amount of time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The exact origins of the name Narcissus is mysterious, but it is often associated with a Greek phrase for intoxicated (narcotic) and the myth of the junior of that name who fell in love with his own representation. The English expression 'daffodil' is apparently 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 variety in the Traditional western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were unveiled in to the ASIA to the tenth hundred years prior. 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 tourism and urbanisation.
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 past due 19th century were an important commercial crop centred mostly on holland. Narcissi are popular as lower blooms and since ornamental plants in private and general public gardens today. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering an array of colours and shapes. Like other members of the family, narcissi produce 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 used in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in skill and literature, narcissi are associated with a true number of themes in various cultures, ranging from loss of life to good fortune, and as symbols of spring and coil. The daffodil is the national bloom of Wales and the symbol of cancer tumor charities in many countries. The appearance of the outdoors flowers in spring and coil is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to an underground storage light. They regrow in the next yr from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf types such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might increase as extra tall as 80 cm.
The vegetation are scapose, having an individual central leafless hollow blossom stem (scape). Several blue-green or green, small, strap-shaped leaves occur from the light bulb. The flower stem usually bears a solitary bloom, but once in a while a cluster of plants (umbel). The flowers, that are conspicuous and white or yellowish usually, sometimes both or seldom green, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an external ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical molded corona. The blossoms may suspend down (pendent), or be erect. There are six pollen bearing stamens encompassing a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The berry includes a dried out capsule that splits (dehisces) liberating numerous black seed products.
The bulb sits dormant after the leaves and flower stem die again and has contractile origins that pull it down further into the soil. The blossom stem and leaves form in the light, to emerge the following season. Most types are dormant from summer time to late winter, flowering in the planting season, though a few kinds are fall months flowering.
