Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common labels 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 a cup- or trumpet-shaped corona. The blossoms are usually white or yellow (orange or pink in garden types), with either standard or contrasting colored tepals and corona.
Narcissus were well known in early civilisation, both medicinally and botanically, but formally identified by Linnaeus in his Types Plantarum (1753). The genus is normally thought to have about ten areas with about 50 species. The true quantity of types has varied, depending on how they are grouped, thanks 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 origins of the real name Narcissus is unfamiliar, but it is often associated with a Greek term for intoxicated (narcotic) and the myth of the children of that name who fell in love with his own representation. The English word 'daffodil' is apparently produced from "asphodel", with which it was commonly compared.
The varieties are native to meadows and woods in southern Europe and North Africa with a centre of diversity in the European Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were unveiled 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, diseases and disorders include viruses, fungi, the larvae of flies, nematodes and mites. Some Narcissus species have become extinct, while some are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe following the 16th hundred years and by the past due 19th century were an important commercial crop centred primarily on the Netherlands. Narcissi are popular as trim bouquets so that ornamental plants in private and public gardens today. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a variety of colours and shapes. 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 accidentally ingested. This property has been exploited for medicinal used in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in books and art work, narcissi are associated with a number of themes in various cultures, ranging from fatality to good fortune, and as symbols of planting season. The daffodil is the nationwide bloom of Wales and the symbol of cancer tumor charities in many countries. The appearance of the crazy 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 the underground storage light. They regrow in the following calendar year from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm depending on species. Dwarf species such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may expand as high as 80 cm.
The vegetation are scapose, having an individual central leafless hollow flower stem (scape). Several green or blue-green, thin, strap-shaped leaves happen from the bulb. The herb stem usually bears a solitary bloom, but sometimes a cluster of blooms (umbel). The blooms, which are conspicuous and white or yellow usually, sometimes both or almost never renewable, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outer ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical molded corona. The plants may hang down (pendent), or be erect. You will discover six pollen bearing stamens adjoining a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The fruits involves a dried capsule that splits (dehisces) launching numerous black seed products.
The bulb is situated dormant after the leaves and blossom stem die back and has contractile origins that pull it down further in to the soil. The bloom leaves and stem form in the light bulb, to emerge the next season. Most kinds are dormant from summer to later winter, flowering in the spring and coil, though a few kinds are fall months flowering.
