Narcissus /n?:r's?s?s/ is a genus of mainly 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 blooms are usually white or yellowish (orange or red in garden kinds), with either standard or contrasting colored tepals and corona.
Narcissus were popular in ancient civilisation, both and botanically medicinally, but formally explained by Linnaeus in his Kinds Plantarum (1753). The genus is generally thought to have about ten portions with approximately 50 species. The true volume of types has mixed, depending on how they are categorized, a consequence of to similarity between hybridization and species. The genus arose some right time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The exact source of the real name Narcissus is unknown, but it is linked to a Greek term for intoxicated (narcotic) and the misconception of the young ones of that name who fell deeply in love with his own reflection. The English term 'daffodil' appears to be derived from "asphodel", with which it was likened commonly.
The varieties are native to meadows and woods in southern Europe and North Africa with a centre of diversity in the Traditional western Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were presented into the ASIA to the tenth hundred years prior. 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 tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the initial times, but became ever more popular in Europe following the 16th century and by the past due 19th hundred years were an important commercial crop centred mainly on the Netherlands. Today narcissi are popular as chop blossoms and as ornamental crops in private and general population gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering a variety of shapes and colours. Like other members of these 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 use in 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 various cultures, ranging from loss of life to fortune, and as symbols of planting season. The daffodil is the nationwide blossom of Wales and the mark of tumor charities in many countries. The appearance of the outrageous flowers in spring and coil is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering for an underground storage light bulb. They regrow in the next year from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm depending on species. Dwarf kinds such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may grow as large as 80 cm.
The vegetation are scapose, having an individual central leafless hollow rose stem (scape). Several blue-green or green, narrow, strap-shaped leaves occur from the light bulb. The flower stem usually bears a solitary flower, but occasionally a cluster of blooms (umbel). The flowers, which can be conspicuous and white or yellow usually, sometimes both or almost never green, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an external ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical shaped corona. The plants may hang down (pendent), or be erect. A couple of six pollen bearing stamens encircling a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The fruit includes a dried up capsule that splits (dehisces) releasing numerous black seed products.
The bulb is dormant after the leaves and blossom stem die back again and has contractile roots that take it down further in to the soil. The blossom leaves and stem form in the bulb, to emerge the following season. Most species are dormant from summer to late winter, flowering in the springtime, though a few species are fall flowering.
