Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common names 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 with a cup- or trumpet-shaped corona. The blossoms are generally white or yellowish (orange or pink in garden types), with either standard or contrasting colored tepals and corona.
Narcissus were popular in historic civilisation, both medicinally and botanically, but formally detailed by Linnaeus in his Kinds Plantarum (1753). The genus is normally thought to have about ten sections with approximately 50 species. The amount of types has mixed, depending how they are labeled, a consequence of to similarity between hybridization and types. 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 origins of the true name Narcissus is mysterious, but it is associated with a Greek expression for intoxicated (narcotic) and the myth of the youth of this name who fell in love with his own reflection. The English phrase 'daffodil' appears to be derived from "asphodel", with which it was likened commonly.
The types are native to meadows and woods in southern European countries and North Africa with a middle of variety in the American Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were introduced in to the Far East before the tenth century. 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 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 increasingly popular in Europe following the 16th century and by the later 19th century were an important commercial crop centred generally on the Netherlands. Today narcissi are popular as slice flowers 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 classified into divisions, covering a wide range of colours and shapes. Like other members of the family, narcissi create 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 use in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in literature and skill, narcissi are associated with a number of themes in several cultures, ranging from death to fortune, and as icons of spring. The daffodil is the nationwide bloom of Wales and the sign of malignancy charities in many countries. The appearance of the crazy flowers in spring and coil is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering with an underground storage light bulb. They regrow in the following 12 months from brown-skinned ovoid bulbs with pronounced necks, and reach levels of 5-80 cm depending on the species. Dwarf kinds such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may develop as large as 80 cm.
The plants are scapose, having a single central leafless hollow bloom stem (scape). Several blue-green or green, small, strap-shaped leaves arise from the light bulb. The flower stem bears a solitary rose, but once in a while a cluster of bouquets (umbel). The blossoms, that happen to be usually conspicuous and white or yellow, both or rarely renewable sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outside ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical formed corona. The bouquets may hang down (pendent), or be erect. There are six pollen bearing stamens encompassing a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The berry contains a dried out capsule that splits (dehisces) releasing numerous black seed products.
The bulb is situated dormant after the leaves and blossom stem die again and has contractile origins that yank it down further in to the soil. The flower leaves and stem form in the light bulb, to emerge the following season. Most kinds are dormant from summer to late winter, flowering in the springtime, though a few species are autumn flowering.
