Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common labels 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 by the cup- or trumpet-shaped corona. The flowers are generally white or yellowish (orange or green in garden kinds), with either even or contrasting colored corona and tepals.
Narcissus were popular in traditional civilisation, both medicinally and botanically, but formally defined by Linnaeus in his Varieties Plantarum (1753). The genus is normally thought to have about ten areas with around 50 species. The amount of species has varied, depending on how they are categorized, 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 regions of southwest Europe. The exact origins of the name Narcissus is anonymous, but it is linked to a Greek expression for intoxicated (narcotic) and the myth of the junior of this name who fell in love with his own representation. The English expression 'daffodil' appears to be produced from "asphodel", with which it was likened commonly.
The kinds are indigenous to meadows and woods in southern European countries and North Africa with a centre of variety in the European Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were created into the ASIA to the tenth hundred years prior. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are insect-pollinated also. Known pests, diseases and disorders include viruses, fungi, the larvae of flies, nematodes and mites. Some Narcissus species have grown to be extinct, while others are threatened by increasing urbanisation and tourism.
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 century were an important commercial crop centred generally on the Netherlands. Narcissi are popular as slash flowers so when ornamental plants in private and general population gardens today. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering an array 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 ingested accidentally. This property has been exploited for medicinal use in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in artwork and books, narcissi are associated with a number of themes in several cultures, ranging from death to good fortune, and as icons of spring and coil. The daffodil is the countrywide blossom of Wales and the image of tumors charities in many countries. The looks of the outrageous flowers in spring and coil is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to the underground storage light. They regrow in the next 12 months from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm depending on species. Dwarf varieties such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may develop as high as 80 cm.
The crops are scapose, having a single central leafless hollow rose stem (scape). Several green or blue-green, small, strap-shaped leaves occur from the light. The seed stem bears a solitary rose, but once in a while a cluster of bouquets (umbel). The bouquets, which are conspicuous and white or yellow usually, sometimes both or seldom green, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an exterior ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical formed corona. The blossoms may suspend down (pendent), or be erect. You will discover six pollen bearing stamens encircling a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The berry consists of a dried capsule that splits (dehisces) liberating numerous black seed products.
The bulb is situated dormant after the leaves and bloom stem die again and has contractile root base that pull it down further in to the soil. The flower leaves and stem form in the bulb, to emerge the following season. Most species are dormant from summer to past due winter, flowering in the planting season, though a few species are fall flowering.
