Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial vegetation 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 members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by the cup- or trumpet-shaped corona. The plants are usually white or yellowish (orange or pink in garden types), with either standard or contrasting colored corona and tepals.
Narcissus were popular in traditional civilisation, both and botanically medicinally, but formally explained by Linnaeus in his Varieties Plantarum (1753). The genus is normally considered to have about ten parts with around 50 species. The number of species has assorted, depending how they are categorized, due to similarity between hybridization and kinds. 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 origin of the name Narcissus is undiscovered, but it is associated with a Greek phrase for intoxicated (narcotic) and the myth of the youngsters of that name who fell in love with his own representation. The English expression 'daffodil' appears to be produced from "asphodel", with which it was compared commonly.
The types are local to meadows and woods in southern European countries and North Africa with a centre of variety in the Traditional western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild 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 also insect-pollinated. 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 tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe after the 16th century and by the past due 19th century were an important commercial crop centred generally on holland. Today narcissi are popular as slash blossoms as ornamental crops in private and general population gardens. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering an array of colours and shapes. Like other members with their family, narcissi create a number of different alkaloids, which provide some protection for the plant, but may be poisonous if accidentally ingested. This property has been exploited for medicinal utilization in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in books and skill, narcissi are associated with a number of themes in various cultures, ranging from fatality to good fortune, and as icons of spring. The daffodil is the national rose of Wales and the sign of cancers charities in many countries. The appearance 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 after flowering to a underground storage bulb. They regrow in the next time from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm with regards to the species. Dwarf kinds such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may increase as tall as 80 cm.
The plant life are scapose, having an individual central leafless hollow blossom stem (scape). Several green or blue-green, thin, strap-shaped leaves happen from the bulb. The herb stem bears a solitary rose, but sometimes a cluster of blooms (umbel). The plants, that happen to be conspicuous and white or yellow usually, sometimes both or rarely green, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outside ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical designed corona. The blooms may suspend down (pendent), or be erect. A couple of six pollen bearing stamens encompassing a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The fruit contains a dry out capsule that splits (dehisces) liberating numerous black seed products.
The bulb lies dormant following the leaves and bloom stem die again and has contractile origins that pull it down further into the soil. The bloom stem and leaves form in the light bulb, to emerge the next season. Most kinds are dormant from summer season to past due winter, flowering in the planting season, though a few types are fall months flowering.
