Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common titles 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 way of a cup- or trumpet-shaped corona. The bouquets are usually white or yellowish (orange or red in garden types), with either standard or contrasting colored corona and tepals.
Narcissus were popular in historical civilisation, both medicinally and botanically, but formally referred to by Linnaeus in his Types Plantarum (1753). The genus is generally considered to have about ten sections with around 50 species. The true quantity of species has assorted, depending on how they are labeled, due to similarity between hybridization and species. 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 origins of the name Narcissus is mysterious, but it is often linked to a Greek phrase for intoxicated (narcotic) and the myth of the junior of that name who fell deeply in love with his own representation. The English term 'daffodil' appears to be derived from "asphodel", with which it was commonly likened.
The varieties are local to meadows and woods in southern European countries and North Africa with a centre 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 some are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the earliest 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 generally on the Netherlands. Today narcissi are popular as slash flowers and as ornamental vegetation in private and public gardens. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a variety of colours and shapes. Like other members of the family, narcissi produce a true number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested unintentionally. This property has been exploited for medicinal use in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in literature and art work, narcissi are associated with a true number of themes in several cultures, ranging from loss of life to fortune, and as symbols of springtime. The daffodil is the nationwide flower of Wales and the sign of cancer tumor charities in many countries. The appearance of the outrageous flowers in spring 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 bulb. They regrow in the next season from brown-skinned ovoid bulbs with pronounced necks, and reach heights 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 increase as large as 80 cm.
The crops are scapose, having a single central leafless hollow bloom stem (scape). Several green or blue-green, narrow, strap-shaped leaves come up from the light bulb. The flower stem bears a solitary rose, but sometimes a cluster of plants (umbel). The blossoms, which can be conspicuous and white or yellowish usually, 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 exterior ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical shaped corona. The blooms may suspend down (pendent), or be erect. You will find six pollen bearing stamens adjoining a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The fruit contains a dry out capsule that splits (dehisces) liberating numerous black seed products.
The bulb is situated dormant following the leaves and bloom stem die back again and has contractile root base that pull it down further into the soil. The bloom stem and leaves form in the bulb, to emerge the next season. Most types are dormant from summer time to late winter, flowering in the planting season, though a few varieties are fall months flowering.
