Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plants 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 members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by a cup- or trumpet-shaped corona. The plants are usually white or yellowish (orange or pink in garden kinds), with either uniform or contrasting coloured tepals and corona.
Narcissus were popular in ancient civilisation, both medicinally and botanically, but formally defined by Linnaeus in his Types Plantarum (1753). The genus is normally considered to have about ten portions with approximately 50 species. The amount of kinds has mixed, depending about how they are classified, anticipated to similarity between types and hybridization. The genus arose some right time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise origin of the name Narcissus is anonymous, but it is linked to a Greek expression for intoxicated (narcotic) and the misconception of the young ones of that name who fell in love with his own representation. The English expression 'daffodil' is apparently produced from "asphodel", with which it was likened commonly.
The varieties are indigenous to meadows and woods in southern European countries and North Africa with a centre of diversity in the European 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 also insect-pollinated. Known pests, diseases and disorders include viruses, fungi, the larvae of flies, nematodes and mites. 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 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 mainly on the Netherlands. Today narcissi are popular as slice blossoms so when ornamental plants in private and public gardens. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering an array of shapes and colours. Like other members with their family, narcissi produce a true 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 use within traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in fine art and literature, narcissi are associated with a number of themes in several cultures, ranging from loss of life to fortune, and as icons of spring. The daffodil is the national flower of Wales and the sign of cancers charities in many countries. The appearance of the crazy flowers in springtime is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to an underground storage light. They regrow in the next 12 months from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm depending on the species. Dwarf types such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might develop as tall as 80 cm.
The plants are scapose, having an individual central leafless hollow rose stem (scape). Several blue-green or green, thin, strap-shaped leaves come up from the light bulb. The seed stem bears a solitary bloom, but once in a while a cluster of blooms (umbel). The bouquets, which are conspicuous and white or yellowish usually, sometimes both or hardly ever inexperienced, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outside ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The flowers may suspend down (pendent), or be erect. You will discover six pollen bearing stamens encompassing a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The fruits consists of a dried capsule that splits (dehisces) liberating numerous black seed products.
The bulb sits dormant following the leaves and bloom stem die again and has contractile root base that draw it down further into the soil. The bloom leaves and stem form in the bulb, to emerge the following season. Most kinds are dormant from summer to later winter, flowering in the springtime, though a few types are autumn flowering.
