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 with a cup- or trumpet-shaped corona. The bouquets are usually white or yellowish (orange or red in garden types), with either uniform or contrasting colored tepals and corona.
Narcissus were popular in traditional civilisation, both and botanically medicinally, but formally defined by Linnaeus in his Varieties Plantarum (1753). The genus is generally considered to have about ten areas with approximately 50 species. The amount of types has varied, depending about how they are classified, anticipated to similarity between types and hybridization. The genus arose some right amount of time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise origin of the real name Narcissus is undiscovered, but it is often associated with a Greek term for intoxicated (narcotic) and the myth of the junior of this name who fell deeply in love with his own representation. The English word 'daffodil' is apparently derived from "asphodel", with which it was commonly compared.
The kinds are native to meadows and woods in southern European countries and North Africa with a middle of diversity in the American Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were released into the ASIA to the tenth century 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 tourism and urbanisation.
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 later 19th hundred years were an important commercial crop centred generally on the Netherlands. Narcissi are popular as cut flowers so when ornamental vegetation 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 labeled 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 inadvertently. This property has been exploited for medicinal use within traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in books and artwork, narcissi are associated with a number of themes in several cultures, ranging from fatality to good fortune, and as symbols of planting season. The daffodil is the countrywide rose of Wales and the sign of cancer charities in many countries. The looks of the wild flowers in spring 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 bulb. They regrow in the next season from brown-skinned ovoid bulbs with pronounced necks, and reach levels of 5-80 cm with respect to the species. Dwarf types such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might expand as high as 80 cm.
The plants are scapose, having a single central leafless hollow blossom stem (scape). Several green or blue-green, narrow, strap-shaped leaves come up from the light. The place stem usually bears a solitary rose, but occasionally a cluster of bouquets (umbel). The blooms, which can be usually conspicuous and white or yellow, both or seldom inexperienced sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an external ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical designed corona. The bouquets may hang down (pendent), or be erect. You can find six pollen bearing stamens bordering a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The super fruit includes a dry out capsule that splits (dehisces) liberating numerous black seeds.
The bulb lays dormant following the leaves and rose stem die back again and has contractile origins that pull it down further in to the soil. The blossom stem and leaves form in the light, to emerge the next season. Most species are dormant from summer to late winter, flowering in the spring, though a few types are fall flowering.
