Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common brands 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 usually white or yellowish (orange or red in garden types), with either uniform or contrasting coloured tepals and corona.
Narcissus were popular in ancient civilisation, both and botanically medicinally, but formally explained by Linnaeus in his Kinds Plantarum (1753). The genus is normally thought to have about ten portions with approximately 50 species. The number of kinds has varied, depending how they are classified, scheduled to similarity between varieties and hybridization. The genus arose some right amount of time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact source of the real name Narcissus is unidentified, but it is linked to a Greek term for intoxicated (narcotic) and the misconception of the youngsters of this name who fell deeply in love with his own representation. The English word 'daffodil' appears to be derived from "asphodel", with which it was likened commonly.
The types are indigenous to meadows and woods in southern Europe and North Africa with a middle of variety in the Traditional western Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were created into the Far East 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, disorders and diseases include viruses, fungi, the larvae of flies, nematodes and mites. Some Narcissus species have become extinct, while others are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the initial times, but became ever more popular in Europe following the 16th hundred years and by the late 19th hundred years were an important commercial crop centred primarily on holland. Today narcissi are popular as cut plants so that as ornamental vegetation in private and 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 shapes and colours. 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 resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in literature and fine art, narcissi are associated with a true number of themes in several cultures, ranging from fatality to good fortune, and as symbols of spring. The daffodil is the nationwide rose of Wales and the mark of tumor charities in many countries. The appearance of the outdoors flowers in springtime 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 next year 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 elevation of 5-8 cm, while Narcissus tazetta might increase as high as 80 cm.
The plants are scapose, having a single central leafless hollow flower stem (scape). Several blue-green or green, small, strap-shaped leaves occur from the bulb. The plant stem bears a solitary rose, but once in a while a cluster of plants (umbel). The plants, which are usually conspicuous and white or yellowish, both or almost never green sometimes, contain 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 shaped corona. The blossoms may suspend down (pendent), or be erect. You will find six pollen bearing stamens encompassing a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The fruits consists of a dry out capsule that splits (dehisces) launching numerous black seeds.
The bulb is placed dormant after the leaves and flower stem die back and has contractile origins that move it down further into the soil. The bloom stem and leaves form in the bulb, to emerge the following season. Most varieties are dormant from summer to later winter, flowering in the planting season, though a few varieties are fall flowering.
