Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial vegetation 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 with a cup- or trumpet-shaped corona. The bouquets are usually white or yellowish (orange or red in garden varieties), with either even or contrasting coloured corona and tepals.
Narcissus were popular in ancient civilisation, both and botanically medicinally, but formally referred to by Linnaeus in his Kinds Plantarum (1753). The genus is generally considered to have about ten sections with roughly 50 species. The amount of varieties has assorted, depending how they are classified, due to similarity between hybridization and types. The genus arose time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise source of the true name Narcissus is unfamiliar, but it is often linked to 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 term 'daffodil' is apparently derived from "asphodel", with which it was compared commonly.
The species are indigenous to meadows and woods in southern Europe 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 released into the ASIA to the tenth century prior. Narcissi tend to be long-lived bulbs, which propagate by division, but are also insect-pollinated. Known pests, diseases and disorders include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have become 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 after the 16th hundred years and by the later 19th century were an important commercial crop centred primarily on the Netherlands. Narcissi are popular as slash bouquets and since ornamental plant life 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 labeled into divisions, covering a wide range of colours and shapes. Like other members of their family, narcissi produce 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 use in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in skill and books, narcissi are associated with a number of themes in various cultures, ranging from death to fortune, and as symbols of spring and coil. The daffodil is the national rose of Wales and the symbol of tumors charities in many countries. The looks of the outdoors flowers in planting season is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering to a underground storage bulb. They regrow in the next year from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf varieties such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might increase as tall as 80 cm.
The crops are scapose, having a single central leafless hollow bloom stem (scape). Several green or blue-green, slim, strap-shaped leaves come up from the light. The seed stem usually bears a solitary flower, but sometimes a cluster of bouquets (umbel). The plants, which can be conspicuous and white or yellowish usually, sometimes both or seldom 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 designed corona. The flowers may hang up down (pendent), or be erect. You will discover six pollen bearing stamens encompassing a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The fruits contains a dried capsule that splits (dehisces) launching numerous black seeds.
The bulb lies dormant after the leaves and flower stem die back again and has contractile origins that move it down further in to the soil. The bloom stem and leaves form in the bulb, to emerge the next season. Most varieties are dormant from summertime to past due winter, flowering in the springtime, though a few species are autumn flowering.
