Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common labels 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 blossoms are generally white or yellow (orange or red in garden types), with either even or contrasting colored corona and tepals.
Narcissus were well known in historical civilisation, both medicinally and botanically, but formally defined by Linnaeus in his Varieties Plantarum (1753). The genus is generally considered to have about ten sections with around 50 species. The true amount of varieties has mixed, depending how they are categorized, credited to similarity between types and hybridization. The genus arose some time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise origins of the name Narcissus is unidentified, but it is associated with a Greek word 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 produced from "asphodel", with which it was compared commonly.
The species are indigenous to meadows and woods in southern European countries and North Africa with a center of diversity in the Traditional western Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were created into the Far East to the tenth century 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, mites and nematodes. Some Narcissus species have become extinct, while others are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the earliest 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 primarily on the Netherlands. Today narcissi are popular as chop plants and as ornamental vegetation in private and general population gardens. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering a wide range of shapes and colours. Like other members of their family, narcissi create a true number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested unintentionally. 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 fine art and books, narcissi are associated with a true number of themes in several cultures, ranging from loss of life to good fortune, and as icons of springtime. The daffodil is the national blossom of Wales and the symbol of tumors charities in many countries. The appearance of the crazy flowers in spring is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to the underground storage light. They regrow in the following year from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm depending on species. Dwarf types such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may expand as extra tall as 80 cm.
The crops are scapose, having a single central leafless hollow flower stem (scape). Several blue-green or green, narrow, strap-shaped leaves happen from the light bulb. The seed stem bears a solitary blossom, but sometimes a cluster of bouquets (umbel). The bouquets, that happen to be conspicuous and white or yellowish usually, sometimes both or rarely green, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an exterior ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical molded corona. The blossoms may hang down (pendent), or be erect. You will find six pollen bearing stamens encompassing a central style. The ovary is second-rate (below the floral parts) consisting of three chambers (trilocular). The fruit consists of a dry out capsule that splits (dehisces) liberating numerous black seed products.
The bulb is dormant after the leaves and flower stem die back again and has contractile origins that draw it down further into the soil. The rose stem and leaves form in the light bulb, to emerge the following season. Most species are dormant from summer months to later winter, flowering in the spring and coil, though a few varieties are fall flowering.
