Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plant life 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 the cup- or trumpet-shaped corona. The plants are generally white or yellowish (orange or green in garden types), with either standard or contrasting colored corona and tepals.
Narcissus were well known in ancient civilisation, both and botanically medicinally, but formally referred to by Linnaeus in his Kinds Plantarum (1753). The genus is normally considered to have about ten parts with roughly 50 species. The true number of types has assorted, depending how they are classified, anticipated to similarity between types and hybridization. The genus arose some right time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact origins of the real name Narcissus is undiscovered, but it is associated with a Greek term for intoxicated (narcotic) and the myth of the children of this name who fell deeply in love with his own representation. The English expression 'daffodil' is apparently produced from "asphodel", with which it was likened commonly.
The varieties are indigenous to meadows and woods in southern European countries and North Africa with a center of diversity in the European Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were introduced in to the Far East prior to the tenth century. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are insect-pollinated also. Known pests, diseases and disorders include viruses, fungi, the larvae of flies, mites and nematodes. 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 ever more popular in Europe following the 16th century and by the later 19th hundred years were an important commercial crop centred mainly on holland. Narcissi are popular as slash blooms so that ornamental plants in private and general population gardens today. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering a wide range of shapes and colours. Like other members of the family, narcissi produce a true number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested unintentionally. This property has been exploited for medicinal use in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in books and art, narcissi are associated with a true number of themes in various cultures, ranging from fatality to good fortune, and as icons of springtime. The daffodil is the national blossom of Wales and the symbol of cancer charities in many countries. The appearance of the wild flowers in spring is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering to the underground storage bulb. They regrow in the following 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 height of 5-8 cm, while Narcissus tazetta may grow as extra tall as 80 cm.
The crops are scapose, having a single central leafless hollow flower stem (scape). Several blue-green or green, slim, strap-shaped leaves arise from the bulb. The vegetable stem bears a solitary blossom, but once in a while a cluster of blooms (umbel). The bouquets, which can be conspicuous and white or yellowish usually, sometimes both or rarely inexperienced, 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 disk to conical formed corona. The bouquets may suspend down (pendent), or be erect. A couple of six pollen bearing stamens surrounding a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The berries consists of a dried out capsule that splits (dehisces) launching numerous black seeds.
The bulb is dormant following the leaves and bloom stem die again and has contractile roots that move it down further in to the soil. The bloom stem and leaves form in the light, to emerge the following season. Most species are dormant from summer time to late winter, flowering in the spring and coil, though a few species are fall flowering.
