Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common brands including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are used to describe all or some members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by the cup- or trumpet-shaped corona. The plants are usually white or yellowish (orange or green in garden kinds), with either even or contrasting coloured corona and tepals.
Narcissus were well known in old civilisation, both medicinally and botanically, but formally described by Linnaeus in his Species Plantarum (1753). The genus is normally thought to have about ten areas with about 50 species. The number of types has assorted, depending on how they are labeled, as a consequence to similarity between hybridization and kinds. The genus arose time 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 unknown, but it is linked to a Greek term for intoxicated (narcotic) and the myth of the youth of this name who fell in love with his own reflection. The English term 'daffodil' appears to be derived from "asphodel", with which it was commonly compared.
The types are indigenous to meadows and woods in southern European countries and North Africa with a middle of diversity in the American Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were launched into the Far East to the tenth century prior. Narcissi have a tendency 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, mites and nematodes. Some Narcissus species have grown to be extinct, while others 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 after the 16th hundred years and by the later 19th hundred years were an important commercial crop centred mainly on holland. Today narcissi are popular as slash blossoms so when ornamental vegetation in private and general population gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a wide range of shapes and colours. Like other members of these family, narcissi produce a true 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 within traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in skill and literature, narcissi are associated with a true number of themes in several cultures, ranging from loss of life to good fortune, and as symbols of spring and coil. The daffodil is the countrywide blossom of Wales and the icon of cancers charities in many countries. The looks of the wild flowers in springtime is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to an underground storage bulb. They regrow in the next yr from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf species such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might grow as high as 80 cm.
The vegetation are scapose, having a single central leafless hollow blossom stem (scape). Several blue-green or green, slim, strap-shaped leaves arise from the light bulb. The vegetable stem bears a solitary bloom, but occasionally a cluster of blooms (umbel). The flowers, that happen to be usually conspicuous and white or yellowish, sometimes both or seldom renewable, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outside ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical designed corona. The bouquets may suspend down (pendent), or be erect. There are six pollen bearing stamens bordering a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The berry involves a dried capsule that splits (dehisces) releasing numerous black seeds.
The bulb is situated dormant following the leaves and flower stem die back and has contractile origins that pull it down further in to the soil. The rose leaves and stem form in the light bulb, to emerge the following season. Most types are dormant from summertime to past due winter, flowering in the spring and coil, though a few types are autumn flowering.
