Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plant life 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 a cup- or trumpet-shaped corona. The blooms are generally white or yellow (orange or green in garden varieties), with either standard or contrasting colored tepals and corona.
Narcissus were well known in traditional civilisation, both and botanically medicinally, but formally defined by Linnaeus in his Kinds Plantarum (1753). The genus is generally considered to have about ten areas with approximately 50 species. The amount of species has assorted, depending about how they are grouped, as a consequence to similarity between hybridization and varieties. 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 unfamiliar, but it is often linked to a Greek phrase for intoxicated (narcotic) and the misconception of the young ones of that name who fell in love with his own reflection. The English word 'daffodil' appears to be derived from "asphodel", with which it was commonly compared.
The varieties are native 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 cultivated and wild plants have naturalised widely, and were introduced in to the Far East prior to the tenth century. 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, 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 later 19th century were an important commercial crop centred primarily on the Netherlands. Today narcissi are popular as slash blooms and since ornamental plant life 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 a variety of shapes and colours. Like other members of these family, narcissi create a true 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 utilization in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in literature and artwork, narcissi are associated with a true number of themes in different cultures, ranging from death to fortune, and as symbols of spring and coil. The daffodil is the countrywide blossom of Wales and the sign of cancer tumor charities in many countries. The appearance of the outdoors flowers in springtime 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 bulb. They regrow in the following 12 months from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf varieties such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may grow as large as 80 cm.
The plant life are scapose, having a single central leafless hollow blossom stem (scape). Several green or blue-green, small, strap-shaped leaves occur from the bulb. The place stem bears a solitary bloom, but sometimes a cluster of blossoms (umbel). The blooms, which are usually conspicuous and white or yellow, both or almost never green sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an external ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical shaped corona. The plants may suspend down (pendent), or be erect. You will find six pollen bearing stamens surrounding a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The fruits consists of a dried capsule that splits (dehisces) launching numerous black seeds.
The bulb lies dormant following the leaves and blossom stem die back and has contractile origins that pull it down further in to the soil. The flower stem and leaves form in the bulb, to emerge the next season. Most varieties are dormant from warmer summer months to later winter, flowering in the springtime, though a few varieties are autumn flowering.
