Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plant life 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 types), with either even or contrasting coloured corona and tepals.
Narcissus were popular in old civilisation, both and botanically medicinally, but formally referred to by Linnaeus in his Types Plantarum (1753). The genus is normally considered to have about ten parts with approximately 50 species. The amount of kinds has assorted, depending on how they are categorised, thanks to similarity between hybridization and species. The genus arose some time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise source of the true name Narcissus is unknown, but it is linked to a Greek phrase for intoxicated (narcotic) and the myth of the young ones of that name who fell in love with his own reflection. The English expression 'daffodil' appears to be produced from "asphodel", with which it was commonly likened.
The varieties are indigenous to meadows and woods in southern Europe and North Africa with a middle of diversity in the Western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were introduced into the Far East before the tenth century. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are also insect-pollinated. Known pests, diseases and disorders include viruses, fungi, the larvae of flies, nematodes and mites. Some Narcissus species have grown to be extinct, while some are threatened by increasing tourism and urbanisation.
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 mainly on the Netherlands. Today narcissi are popular as slice blooms and as ornamental vegetation in private and general public gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering a wide range of colours and shapes. Like other members of the family, narcissi produce a number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested accidentally. This property has been exploited for medicinal use in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in art and books, narcissi are associated with a number of themes in several cultures, ranging from loss of life to good fortune, and as symbols of planting season. The daffodil is the nationwide rose of Wales and the icon of malignancy charities in many countries. The looks of the wild flowers in planting season is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering to a underground storage bulb. They regrow in the following yr from brown-skinned ovoid 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 may grow as large as 80 cm.
The vegetation are scapose, having an individual central leafless hollow blossom stem (scape). Several blue-green or green, slim, strap-shaped leaves happen from the bulb. The vegetable stem usually bears a solitary blossom, but occasionally a cluster of blossoms (umbel). The plants, which can be usually conspicuous and white or yellow, both or hardly ever renewable sometimes, consist of 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 formed corona. The blossoms may hang up down (pendent), or be erect. You will find six pollen bearing stamens bordering a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The fruits consists of a dry out capsule that splits (dehisces) launching numerous black seeds.
The bulb lays dormant after the leaves and flower stem die back again and has contractile root base that move it down further in to the soil. The flower leaves and stem form in the light bulb, to emerge the next season. Most types are dormant from summer season to past due winter, flowering in the planting season, though a few kinds are fall months flowering.
