Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial vegetation 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 way of a cup- or trumpet-shaped corona. The plants are generally white or yellowish (orange or pink in garden kinds), with either standard or contrasting coloured corona and tepals.
Narcissus were popular in ancient civilisation, both and botanically medicinally, but formally referred to by Linnaeus in his Kinds Plantarum (1753). The genus is normally thought to have about ten parts with roughly 50 species. The amount of types has mixed, depending on how they are classified, thanks to similarity between hybridization and varieties. The genus arose a while 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 undiscovered, but it is associated with a Greek phrase for intoxicated (narcotic) and the myth of the youth of this name who fell in love with his own reflection. The English phrase 'daffodil' appears to be derived from "asphodel", with which it was commonly likened.
The varieties are indigenous to meadows and woods in southern European countries and North Africa with a middle of variety in the 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 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 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 ever more popular in Europe after the 16th century and by the later 19th century were an important commercial crop centred primarily on holland. Narcissi are popular as slice bouquets and as ornamental crops in private and general public gardens today. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering a wide range of colours and shapes. 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 ingested inadvertently. This property has been exploited for medicinal utilization in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in books and art work, narcissi are associated with a number of themes in different cultures, ranging from loss of life to fortune, and as icons of planting season. The daffodil is the nationwide blossom of Wales and the sign of cancer charities in many countries. The appearance 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 again after flowering to the underground storage light bulb. They regrow in the next time from brown-skinned ovoid bulbs with pronounced necks, and reach levels of 5-80 cm depending on species. Dwarf kinds such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might develop as extra tall as 80 cm.
The plants are scapose, having an individual central leafless hollow bloom stem (scape). Several blue-green or green, thin, strap-shaped leaves happen from the light bulb. The place stem usually bears a solitary bloom, but sometimes a cluster of plants (umbel). The blossoms, that happen to be usually conspicuous and white or yellowish, sometimes both or hardly ever renewable, 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 disc to conical molded corona. The blossoms may suspend down (pendent), or be erect. You will find six pollen bearing stamens surrounding a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The super fruit involves a dried up capsule that splits (dehisces) releasing numerous black seeds.
The bulb is placed dormant following the leaves and rose stem die again and has contractile roots that pull it down further into the soil. The blossom stem and leaves form in the light, to emerge the next season. Most varieties are dormant from summer time to overdue winter, flowering in the springtime, though a few varieties are autumn flowering.
