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 with a cup- or trumpet-shaped corona. The plants are usually white or yellowish (orange or pink in garden types), with either standard or contrasting coloured tepals and corona.
Narcissus were popular in old civilisation, both and botanically medicinally, but formally defined by Linnaeus in his Varieties Plantarum (1753). The genus is generally considered to have about ten sections with approximately 50 species. The true volume of kinds has varied, depending on how they are classified, due 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 exact origin of the name Narcissus is undiscovered, but it is linked to a Greek phrase for intoxicated (narcotic) and the misconception of the junior of this name who fell deeply in love with his own representation. The English word 'daffodil' appears to be derived from "asphodel", with which it was commonly likened.
The kinds are local to meadows and woods in southern European countries and North Africa with a middle of diversity in the Traditional western Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were introduced into the Far East prior to the tenth century. Narcissi tend to be long-lived bulbs, which propagate by division, but are insect-pollinated also. Known pests, disorders and diseases include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have become extinct, while others are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became ever more popular in Europe after the 16th hundred years and by the overdue 19th hundred years were an important commercial crop centred primarily on holland. Today narcissi are popular as cut blossoms and since ornamental plants in private and open public gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a wide range of colours and shapes. 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 ingested unintentionally. This property has been exploited for medicinal use in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in books and skill, narcissi are associated with a number of themes in various cultures, ranging from loss of life to fortune, and as icons of planting season. The daffodil is the national blossom of Wales and the sign of cancer tumor charities in many countries. The appearance of the crazy flowers in planting season is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering with an underground storage light. They regrow in the next year from brown-skinned ovoid bulbs with pronounced necks, and reach levels of 5-80 cm depending on the species. Dwarf species such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might grow as high as 80 cm.
The plants are scapose, having an individual central leafless hollow rose stem (scape). Several green or blue-green, narrow, strap-shaped leaves occur from the bulb. The plant stem bears a solitary flower, but sometimes a cluster of bouquets (umbel). The bouquets, which are conspicuous and white or yellow usually, sometimes both or rarely renewable, contain 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 shaped corona. The blossoms may hang 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 berries includes a dried out capsule that splits (dehisces) launching numerous black seed products.
The bulb is situated dormant after the leaves and blossom stem die back again and has contractile roots that draw it down further into the soil. The bloom leaves and stem form in the light bulb, to emerge the next season. Most varieties are dormant from summer season to later winter, flowering in the springtime, though a few species are fall flowering.
