Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common names including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are being 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 flowers are generally white or yellow (orange or pink in garden kinds), with either uniform or contrasting colored tepals and corona.
Narcissus were popular in ancient civilisation, both medicinally and botanically, but formally explained by Linnaeus in his Types Plantarum (1753). The genus is generally thought to have about ten parts with about 50 species. The number of varieties has varied, depending about how they are classified, thanks to similarity between hybridization and species. The genus arose time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact origin of the name Narcissus is anonymous, but it is associated with a Greek expression for intoxicated (narcotic) and the misconception of the youngsters of this 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 types are local to meadows and woods in southern European countries and North Africa with a middle of variety in the European Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were launched into the ASIA to the tenth hundred years prior. Narcissi tend 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 earliest times, but became increasingly popular in Europe after the 16th century and by the later 19th hundred years were an important commercial crop centred generally on holland. Today narcissi are popular as chop flowers so that as ornamental vegetation in private and general public gardens. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a variety of shapes and colours. Like other members of the 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 art and books, narcissi are associated with a number of themes in different cultures, ranging from fatality to fortune, and as symbols of spring and coil. The daffodil is the countrywide rose of Wales and the symbol of cancer charities in many countries. The appearance of the wild flowers in spring and coil is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering for an underground storage light. They regrow in the following year from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm with regards to the species. Dwarf kinds such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may expand as extra tall as 80 cm.
The vegetation are scapose, having a single central leafless hollow blossom stem (scape). Several blue-green or green, slim, strap-shaped leaves arise from the bulb. The flower stem usually bears a solitary blossom, but sometimes a cluster of blossoms (umbel). The flowers, which are conspicuous and white or yellow usually, sometimes both or almost never renewable, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outer ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical molded corona. The bouquets may hang down (pendent), or be erect. You can find six pollen bearing stamens adjoining a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The berries involves a dry out capsule that splits (dehisces) liberating numerous black seed products.
The bulb sits dormant after the leaves and bloom stem die back again and has contractile roots that pull it down further into the soil. The blossom leaves and stem form in the light bulb, to emerge the next season. Most types are dormant from warmer summer months to late winter, flowering in the spring, though a few types are fall flowering.
