Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plant life 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 known 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 green in garden varieties), with either uniform or contrasting coloured corona and tepals.
Narcissus were well known in traditional civilisation, both and botanically medicinally, but formally explained by Linnaeus in his Types Plantarum (1753). The genus is generally thought to have about ten areas with about 50 species. The true range of kinds has varied, depending on how they are labeled, a consequence of to similarity between hybridization and types. 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 origin of the name Narcissus is anonymous, but it is linked to a Greek term for intoxicated (narcotic) and the myth of the young ones of that name who fell in love with his own reflection. The English word 'daffodil' appears to be produced from "asphodel", with which it was commonly likened.
The types are indigenous to meadows and woods in southern European countries and North Africa with a middle of diversity in the Western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were released into the ASIA to the tenth century prior. Narcissi tend to be long-lived bulbs, which propagate by division, but are insect-pollinated also. 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 urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe after the 16th hundred years and by the overdue 19th hundred years were an important commercial crop centred generally on holland. Narcissi are popular as slash blossoms so that as ornamental crops in private and general population gardens today. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering an array of colours and shapes. Like other members of their family, narcissi produce a number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested accidentally. This property has been exploited for medicinal use within traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in books and skill, narcissi are associated with a true number of themes in several cultures, ranging from fatality to good fortune, and as symbols of spring and coil. The daffodil is the nationwide rose of Wales and the mark of cancer charities in many countries. The looks of the outdoors flowers in spring and coil is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to a underground storage light bulb. They regrow in the next yr from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm depending on species. Dwarf types such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might increase as extra tall as 80 cm.
The crops are scapose, having an individual central leafless hollow blossom stem (scape). Several green or blue-green, slim, strap-shaped leaves arise from the bulb. The seed stem bears a solitary bloom, but once in a while a cluster of flowers (umbel). The plants, that happen to be conspicuous and white or yellowish usually, sometimes both or almost never green, 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 bouquets may hang up down (pendent), or be erect. You can find six pollen bearing stamens adjoining a central style. The ovary is inferior (below the floral parts) consisting of three chambers (trilocular). The fruit contains a dry capsule that splits (dehisces) launching numerous black seeds.
The bulb sits dormant following the leaves and rose stem die back and has contractile origins that draw it down further into the soil. The bloom stem and leaves form in the light bulb, to emerge the next season. Most types are dormant from summertime to later winter, flowering in the spring and coil, though a few types are fall flowering.
