Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plant life 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 with a cup- or trumpet-shaped corona. The blossoms are generally white or yellow (orange or green in garden kinds), with either standard or contrasting colored tepals and corona.
Narcissus were well known in early civilisation, both and botanically medicinally, but formally detailed by Linnaeus in his Varieties Plantarum (1753). The genus is generally considered to have about ten sections with around 50 species. The amount of types has mixed, depending on how they are categorized, scheduled to similarity between species and hybridization. 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 origins of the true name Narcissus is unknown, but it is associated with a Greek phrase 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' appears to be derived from "asphodel", with which it was compared commonly.
The types are local to meadows and woods in southern European countries and North Africa with a centre of diversity in the American Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were created into the ASIA to the tenth hundred years prior. 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, nematodes and mites. 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 hundred years and by the late 19th hundred years were an important commercial crop centred primarily on holland. Today narcissi are popular as slash plants and since ornamental plant life in private and general public gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering a wide range of colours and shapes. Like other members with their family, narcissi produce a 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 used in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in literature and skill, narcissi are associated with a true number of themes in different cultures, ranging from death to good fortune, and as icons of springtime. The daffodil is the countrywide blossom of Wales and the mark of tumor charities in many countries. The appearance of the outdoors flowers in springtime is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to a underground storage light. They regrow in the following year from brown-skinned ovoid bulbs with pronounced necks, and reach levels of 5-80 cm with respect to the species. Dwarf species such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might grow as extra tall as 80 cm.
The plant life are scapose, having a single central leafless hollow flower stem (scape). Several green or blue-green, narrow, strap-shaped leaves occur from the bulb. The herb stem bears a solitary rose, but sometimes a cluster of blossoms (umbel). The bouquets, that are usually conspicuous and white or yellowish, sometimes both or rarely renewable, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outside ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical designed corona. The blossoms may suspend down (pendent), or be erect. There are six pollen bearing stamens adjoining a central style. The ovary is substandard (below the floral parts) consisting of three chambers (trilocular). The berries includes a dried capsule that splits (dehisces) releasing numerous black seeds.
The bulb is situated dormant following the leaves and blossom stem die again and has contractile root base that pull it down further into the soil. The rose leaves and stem form in the light bulb, to emerge the next season. Most species are dormant from summer to overdue winter, flowering in the spring, though a few species are fall months flowering.
