Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common labels including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are 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 flowers are usually white or yellowish (orange or green in garden kinds), with either standard or contrasting coloured tepals and corona.
Narcissus were popular in ancient civilisation, both and botanically medicinally, but formally referred to by Linnaeus in his Varieties Plantarum (1753). The genus is normally considered to have about ten areas with roughly 50 species. The number of varieties has varied, depending about how they are classified, anticipated to similarity between kinds and hybridization. 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 precise source of the true name Narcissus is unfamiliar, but it is linked to a Greek expression for intoxicated (narcotic) and the myth of the children of that name who fell in love with his own representation. The English term 'daffodil' appears to be derived from "asphodel", with which it was commonly likened.
The species are native to meadows and woods in southern Europe and North Africa with a centre of variety in the Western Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were created into the Far East to the tenth hundred years prior. Narcissi tend to be long-lived bulbs, which propagate by division, but are also insect-pollinated. Known pests, disorders and diseases include viruses, fungi, the larvae of flies, nematodes and mites. Some Narcissus species have become extinct, while others are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe after the 16th century and by the past due 19th hundred years were an important commercial crop centred generally on the Netherlands. Today narcissi are popular as trim flowers so that as ornamental crops in private and open public gardens. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering a variety of colours and shapes. Like other members of their family, narcissi create 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 resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in art and books, narcissi are associated with a true number of themes in different cultures, ranging from loss of life to fortune, and as symbols of planting season. The daffodil is the national rose of Wales and the icon of cancers charities in many countries. The appearance of the untamed 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 bulb. They regrow in the following calendar year from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm with respect to the species. Dwarf varieties such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might grow as high as 80 cm.
The crops are scapose, having an individual central leafless hollow blossom stem (scape). Several blue-green or green, narrow, strap-shaped leaves happen from the bulb. The plant stem bears a solitary rose, but sometimes a cluster of flowers (umbel). The bouquets, that happen to be usually conspicuous and white or yellow, both or hardly ever green sometimes, contain 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 disk to conical formed corona. The blooms may suspend down (pendent), or be erect. There are six pollen bearing stamens adjoining a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The fruit consists of a dry capsule that splits (dehisces) launching numerous black seed products.
The bulb sits dormant after the leaves and blossom stem die again and has contractile roots that pull it down further into the soil. The bloom leaves and stem form in the light, to emerge the following season. Most types are dormant from summer season to late winter, flowering in the spring and coil, though a few kinds are fall months flowering.
