Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common titles 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 by the cup- or trumpet-shaped corona. The blooms are generally white or yellowish (orange or green in garden kinds), with either standard or contrasting colored corona and tepals.
Narcissus were well known in historical civilisation, both and botanically medicinally, but formally defined by Linnaeus in his Varieties Plantarum (1753). The genus is normally thought to have about ten portions with approximately 50 species. The number of types has assorted, depending about how they are categorized, scheduled 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 areas of southwest Europe. The precise origin of the name Narcissus is undiscovered, but it is associated with a Greek term for intoxicated (narcotic) and the misconception of the children of this name who fell deeply in love with his own representation. The English term 'daffodil' appears to be derived from "asphodel", with which it was commonly compared.
The types are indigenous to meadows and woods in southern Europe and North Africa with a center of variety in the American Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were introduced in to the Far East prior to the tenth century. 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 some 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 hundred years and by the past due 19th hundred years were an important commercial crop centred generally on the Netherlands. Narcissi are popular as slice blossoms so that as ornamental plant life in private and public gardens today. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are classified 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 ingested inadvertently. 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 literature and art, narcissi are associated with a true number of themes in different cultures, ranging from fatality to fortune, and as icons of spring and coil. The daffodil is the nationwide bloom of Wales and the sign of tumor charities in many countries. The appearance of the crazy flowers in springtime 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 bulb. They regrow in the next year from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm depending on species. Dwarf kinds 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 rose stem (scape). Several green or blue-green, slim, strap-shaped leaves arise from the light bulb. The seed stem bears a solitary rose, but sometimes a cluster of plants (umbel). The plants, which can be usually conspicuous and white or yellowish, 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 outer ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The plants may hang down (pendent), or be erect. A couple of six pollen bearing stamens encompassing a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The super fruit includes a dried capsule that splits (dehisces) liberating numerous black seed products.
The bulb is situated dormant following the leaves and blossom stem die back again and has contractile origins that draw it down further into the soil. The bloom leaves and stem form in the light, to emerge the next season. Most kinds are dormant from summer months to overdue winter, flowering in the planting season, though a few types are autumn flowering.
