Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common labels 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 usually white or yellowish (orange or green in garden types), with either even or contrasting colored tepals and corona.
Narcissus were well known in historic civilisation, both medicinally and botanically, but formally defined by Linnaeus in his Species Plantarum (1753). The genus is generally thought to have about ten parts with around 50 species. The true volume of varieties has assorted, depending about how they are categorized, thanks 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 areas of southwest Europe. The exact source of the name Narcissus is unknown, but it is associated with a Greek word for intoxicated (narcotic) and the myth of the junior of this name who fell in love with his own reflection. The English expression 'daffodil' appears to be produced from "asphodel", with which it was commonly likened.
The types are indigenous to meadows and woods in southern Europe and North Africa with a centre of variety in the Traditional western Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were introduced in to the Far East before the tenth century. Narcissi tend 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 become extinct, while some are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe following the 16th century and by the overdue 19th hundred years were an important commercial crop centred mostly on holland. Narcissi are popular as chop blossoms so that ornamental plant life in private and public 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 variety of colours and shapes. Like other members of the family, narcissi produce a 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 art and books, narcissi are associated with a true number of themes in several cultures, ranging from death to fortune, and as icons of springtime. The daffodil is the nationwide blossom of Wales and the image of malignancy charities in many countries. The looks of the outdoors flowers in planting season is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to an underground storage bulb. They regrow in the following yr from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm with respect to the species. Dwarf kinds such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might grow as large as 80 cm.
The vegetation are scapose, having an individual central leafless hollow flower stem (scape). Several blue-green or green, narrow, strap-shaped leaves arise from the light. The seed stem bears a solitary bloom, but occasionally a cluster of blooms (umbel). The plants, that are conspicuous and white or yellowish usually, both or almost never green sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outer ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical shaped corona. The flowers may suspend 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 berries contains a dried up capsule that splits (dehisces) launching numerous black seeds.
The bulb sits dormant following the leaves and rose stem die back again and has contractile roots that draw it down further in to the soil. The bloom leaves and stem form in the bulb, to emerge the following season. Most kinds are dormant from summer season to past due winter, flowering in the spring, though a few kinds are fall flowering.
