Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common names 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 red in garden kinds), with either even or contrasting colored corona and tepals.
Narcissus were well known in historic civilisation, both and botanically medicinally, but formally explained by Linnaeus in his Types Plantarum (1753). The genus is generally considered to have about ten sections with approximately 50 species. The amount of types has assorted, depending on how they are grouped, due to similarity between varieties and hybridization. The genus arose time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The exact source of the true name Narcissus is unidentified, but it is often associated with a Greek term for intoxicated (narcotic) and the myth of the children of that name who fell in love with his own representation. The English term 'daffodil' appears to be derived from "asphodel", with which it was likened commonly.
The varieties are indigenous to meadows and woods in southern Europe and North Africa with a middle 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 to the tenth century prior. Narcissi tend to be long-lived bulbs, which propagate by division, but are also insect-pollinated. Known pests, diseases and disorders include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have grown to be 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 after the 16th hundred years and by the overdue 19th hundred years were an important commercial crop centred mostly on the Netherlands. Narcissi are popular as trim blooms and as ornamental vegetation in private and general population gardens today. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a wide range of shapes and colours. Like other members of 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 treating Alzheimer's dementia. Long celebrated in books and fine art, narcissi are associated with a number of themes in various cultures, ranging from death to fortune, and as icons of planting season. The daffodil is the national bloom of Wales and the icon of cancers charities in many countries. The looks of the crazy flowers in planting season is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to an underground storage light bulb. They regrow in the next yr from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm with regards to the species. Dwarf varieties such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may develop as tall as 80 cm.
The vegetation are scapose, having a single central leafless hollow flower stem (scape). Several green or blue-green, small, strap-shaped leaves come up from the light. The herb stem bears a solitary rose, but occasionally a cluster of flowers (umbel). The plants, 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 outside ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical shaped corona. The flowers may hang up down (pendent), or be erect. You can find six pollen bearing stamens adjoining a central style. The ovary is second-rate (below the floral parts) consisting of three chambers (trilocular). The fruits involves a dried out capsule that splits (dehisces) launching numerous black seed products.
The bulb lays dormant following the leaves and bloom stem die back again and has contractile roots that yank it down further in to the soil. The bloom leaves and stem form in the bulb, to emerge the next season. Most varieties are dormant from summertime to overdue winter, flowering in the spring, though a few types are fall months flowering.
