Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common names 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 flowers are generally white or yellowish (orange or red in garden kinds), with either standard or contrasting coloured tepals and corona.
Narcissus were well known in historic civilisation, both medicinally and botanically, but formally identified by Linnaeus in his Types Plantarum (1753). The genus is normally considered to have about ten areas with roughly 50 species. The number of species has mixed, depending about how they are categorized, a consequence of to similarity between hybridization and kinds. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact origins of the true name Narcissus is anonymous, but it is often linked to a Greek term for intoxicated (narcotic) and the misconception of the young ones of this name who fell deeply in love with his own representation. The English expression 'daffodil' appears to be derived from "asphodel", with which it was commonly compared.
The types are indigenous to meadows and woods in southern Europe and North Africa with a middle of variety in the Western Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were introduced into the Far East before the tenth century. Narcissi tend to be long-lived bulbs, which propagate by division, but are also insect-pollinated. Known pests, disorders and diseases include viruses, fungi, the larvae of flies, nematodes and mites. 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 following the 16th century and by the overdue 19th century were an important commercial crop centred primarily on the Netherlands. Narcissi are popular as chop blossoms and as ornamental plant life in private and general public gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering an array 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 inadvertently. This property has been exploited for medicinal use within traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in art work and literature, narcissi are associated with a number of themes in several cultures, ranging from loss of life to fortune, and as icons of planting season. The daffodil is the national flower of Wales and the symbol of tumor charities in many countries. The looks of the wild flowers in planting season is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering to a underground storage light. They regrow in the following 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 elevation of 5-8 cm, while Narcissus tazetta may grow as extra tall as 80 cm.
The plants are scapose, having an individual central leafless hollow flower stem (scape). Several green or blue-green, slim, strap-shaped leaves arise from the light. The flower stem usually bears a solitary bloom, but occasionally a cluster of blossoms (umbel). The plants, that happen to be usually conspicuous and white or yellowish, both or seldom inexperienced sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outer ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical shaped corona. The blooms may hang down (pendent), or be erect. You will find six pollen bearing stamens encircling a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The berries consists of a dry capsule that splits (dehisces) releasing numerous black seed products.
The bulb is dormant following the leaves and flower stem die back and has contractile roots that pull it down further in to the soil. The rose leaves and stem form in the bulb, to emerge the next season. Most species are dormant from summer to late winter, flowering in the spring, though a few species are autumn flowering.
