Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common titles including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are used to describe all or some known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by the cup- or trumpet-shaped corona. The bouquets are usually white or yellowish (orange or pink in garden kinds), with either uniform or contrasting coloured corona and tepals.
Narcissus were well known in historic civilisation, both medicinally and botanically, but formally explained by Linnaeus in his Species Plantarum (1753). The genus is generally thought to have about ten sections with approximately 50 species. The number of kinds has assorted, depending on how they are labeled, as a consequence to similarity between hybridization and types. 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 precise origins of the true name Narcissus is unfamiliar, but it is often associated with a Greek phrase for intoxicated (narcotic) and the misconception of the junior of that name who fell in love with his own representation. The English word 'daffodil' is apparently produced from "asphodel", with which it was commonly compared.
The varieties are indigenous to meadows and woods in southern European countries and North Africa with a centre of diversity in the American Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were unveiled in to the Far East to the tenth hundred years prior. Narcissi tend 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 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 late 19th hundred years were an important commercial crop centred generally on holland. Narcissi are popular as chop bouquets and since ornamental plants in private and open public gardens today. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering an array of shapes and colours. 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 accidentally ingested. 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 number of themes in various cultures, ranging from death to good fortune, and as symbols of planting season. The daffodil is the national flower of Wales and the symbol of cancers charities in many countries. The appearance of the untamed flowers in spring and coil is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to the underground storage bulb. They regrow in the following time from brown-skinned ovoid bulbs with pronounced necks, and reach heights 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 increase as high as 80 cm.
The vegetation are scapose, having a single central leafless hollow flower stem (scape). Several blue-green or green, narrow, strap-shaped leaves happen from the bulb. The place stem usually bears a solitary bloom, but sometimes a cluster of plants (umbel). The blossoms, which can be usually conspicuous and white or yellowish, both or hardly ever inexperienced sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outside ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical designed corona. The plants may suspend down (pendent), or be erect. You will discover six pollen bearing stamens surrounding a central style. The ovary is inferior (below the floral parts) consisting of three chambers (trilocular). The berry includes a dry capsule that splits (dehisces) launching numerous black seeds.
The bulb lies dormant following the leaves and rose stem die back and has contractile origins that move it down further in to the soil. The bloom leaves and stem form in the bulb, to emerge the next season. Most kinds are dormant from summer season to overdue winter, flowering in the spring, though a few kinds are autumn flowering.
