Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common names 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 way of a cup- or trumpet-shaped corona. The blooms are usually white or yellowish (orange or red in garden varieties), with either even or contrasting coloured corona and tepals.
Narcissus were well known in historic civilisation, both medicinally and botanically, but formally referred to by Linnaeus in his Types Plantarum (1753). The genus is generally thought to have about ten areas with roughly 50 species. The true number of kinds has mixed, depending about how they are grouped, as a consequence to similarity between hybridization and species. The genus arose some time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact source of the name Narcissus is mysterious, but it is associated with a Greek word for intoxicated (narcotic) and the myth of the youngsters of that name who fell in love with his own reflection. The English term 'daffodil' is apparently derived from "asphodel", with which it was likened commonly.
The species are local to meadows and woods in southern European countries and North Africa with a center of diversity in the American Mediterranean, particularly the Iberian peninsula. Both wild and cultivated 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 also insect-pollinated. Known pests, disorders and diseases 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 after the 16th century and by the past due 19th hundred years were an important commercial crop centred primarily on the Netherlands. Narcissi are popular as slice plants as ornamental plant life in private and general population gardens today. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering an array of colours and shapes. Like other members with their 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 use within traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in skill and books, narcissi are associated with a number of themes in different cultures, ranging from death to good fortune, and as symbols of spring. The daffodil is the national flower of Wales and the image of tumors charities in many countries. The appearance of the outrageous 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 to the underground storage bulb. They regrow in the next time from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm depending on the species. Dwarf kinds such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may develop as tall as 80 cm.
The plants are scapose, having an individual central leafless hollow flower stem (scape). Several green or blue-green, thin, strap-shaped leaves arise from the bulb. The flower stem bears a solitary blossom, but sometimes a cluster of flowers (umbel). The flowers, that are conspicuous and white or yellowish usually, sometimes both or almost never green, consist of 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 disk to conical shaped corona. The blooms may suspend down (pendent), or be erect. You will discover six pollen bearing stamens surrounding a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The super fruit involves a dry out capsule that splits (dehisces) liberating numerous black seeds.
The bulb is dormant following the leaves and blossom stem die back again and has contractile origins that pull it down further in to the soil. The rose leaves and stem form in the light bulb, to emerge the following season. Most species are dormant from warmer summer months to late winter, flowering in the springtime, though a few varieties are fall flowering.
