Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plants 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 with a cup- or trumpet-shaped corona. The bouquets are generally white or yellow (orange or red in garden kinds), with either standard or contrasting colored tepals and corona.
Narcissus were popular in historic civilisation, both and botanically medicinally, but formally detailed by Linnaeus in his Kinds Plantarum (1753). The genus is normally considered to have about ten sections with around 50 species. The true variety of species has mixed, depending about how they are categorized, credited to similarity between species 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 exact source of the name Narcissus is unidentified, but it is associated with a Greek phrase for intoxicated (narcotic) and the misconception of the junior of that name who fell deeply in love with his own reflection. The English word 'daffodil' is apparently produced from "asphodel", with which it was compared commonly.
The types are indigenous to meadows and woods in southern European countries and North Africa with a center of variety in the European Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were launched into 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, 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 after the 16th century and by the overdue 19th hundred years were an important commercial crop centred generally on holland. Today narcissi are popular as cut plants as ornamental plant life in private and public gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a wide range of colours and shapes. Like other members of these 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 use within traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in artwork and literature, narcissi are associated with a true number of themes in various cultures, ranging from death to fortune, and as icons of springtime. The daffodil is the national bloom of Wales and the mark of cancer tumor charities in many countries. The appearance of the outrageous 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 the underground storage bulb. They regrow in the following year from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm with regards 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 blossom stem (scape). Several green or blue-green, small, strap-shaped leaves happen from the light bulb. The place stem usually bears a solitary blossom, but sometimes a cluster of bouquets (umbel). The blossoms, which can be conspicuous and white or yellow usually, both or almost never green sometimes, consist of 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 disc to conical designed corona. The blossoms may hang down (pendent), or be erect. You can find six pollen bearing stamens encompassing a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The berries involves a dried out capsule that splits (dehisces) liberating numerous black seed products.
The bulb is situated dormant after the leaves and blossom stem die back and has contractile roots that move it down further into the soil. The bloom stem and leaves form in the bulb, to emerge the following season. Most types are dormant from summer months to late winter, flowering in the spring and coil, though a few varieties are autumn flowering.
