Narcissus /n?:r's?s?s/ is a genus of predominantly 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 flowers are usually white or yellowish (orange or pink in garden types), with either even or contrasting coloured tepals and corona.
Narcissus were well known in ancient civilisation, both and botanically medicinally, but formally detailed by Linnaeus in his Species Plantarum (1753). The genus is generally thought to have about ten sections with approximately 50 species. The number of kinds has varied, depending about how they are grouped, scheduled to similarity between varieties and hybridization. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The exact source of the true name Narcissus is unknown, but it is often associated with a Greek phrase for intoxicated (narcotic) and the myth of the young ones of this name who fell in love with his own reflection. The English expression 'daffodil' is apparently produced from "asphodel", with which it was likened commonly.
The species are indigenous to meadows and woods in southern European countries and North Africa with a middle of variety in the Traditional western Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were released into the Far East to the tenth hundred years prior. Narcissi tend 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 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 increasingly popular in Europe after the 16th century and by the past due 19th century were an important commercial crop centred primarily on holland. Narcissi are popular as slash blooms as ornamental vegetation in private and general public 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 variety of shapes and colours. 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 led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in skill and books, narcissi are associated with a true number of themes in different cultures, ranging from loss of life to fortune, and as icons of spring. The daffodil is the countrywide flower of Wales and the image of malignancy charities in many countries. The looks of the outdoors flowers in springtime is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to an underground storage light. They regrow in the following yr from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm depending on the species. Dwarf species such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may develop as tall as 80 cm.
The plant life are scapose, having a single central leafless hollow flower stem (scape). Several green or blue-green, thin, strap-shaped leaves arise from the bulb. The place stem bears a solitary rose, but occasionally a cluster of blossoms (umbel). The plants, which are conspicuous and white or yellow usually, sometimes both or seldom inexperienced, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outside ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical molded corona. The flowers may suspend down (pendent), or be erect. You can find six pollen bearing stamens encompassing a central style. The ovary is inferior (below the floral parts) consisting of three chambers (trilocular). The berry contains a dried up capsule that splits (dehisces) liberating numerous black seed products.
The bulb lies dormant after the leaves and rose stem die back and has contractile origins that pull it down further into the soil. The flower stem and leaves form in the light, to emerge the next season. Most species are dormant from summertime to late winter, flowering in the spring and coil, though a few varieties are fall flowering.
