Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plant life 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 with a cup- or trumpet-shaped corona. The blooms are usually white or yellow (orange or pink in garden varieties), with either standard or contrasting colored tepals and corona.
Narcissus were well known in traditional civilisation, both medicinally and botanically, but formally referred to by Linnaeus in his Species Plantarum (1753). The genus is normally thought to have about ten parts with around 50 species. The true number of varieties has varied, depending about how they are categorised, scheduled to similarity between kinds and hybridization. The genus arose some right time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact origin of the true name Narcissus is unfamiliar, but it is linked to a Greek word for intoxicated (narcotic) and the misconception of the youth of this name who fell in love with his own reflection. The English word 'daffodil' is apparently produced from "asphodel", with which it was likened commonly.
The varieties are local to meadows and woods in southern European countries and North Africa with a middle of variety in the European Mediterranean, the Iberian peninsula particularly. Both wild and cultivated 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 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 urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe following the 16th century and by the late 19th hundred years were an important commercial crop centred generally on the Netherlands. Narcissi are popular as lower blooms so when ornamental vegetation in private and open 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 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 utilization in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in literature and skill, narcissi are associated with a true number of themes in different cultures, ranging from fatality to fortune, and as icons of spring and coil. The daffodil is the countrywide bloom of Wales and the icon of malignancy charities in many countries. The looks of the outdoors flowers in spring and coil is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering with an underground storage light. They regrow in the following 12 months from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm with respect to the species. Dwarf kinds such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might expand as extra tall as 80 cm.
The plants are scapose, having a single central leafless hollow blossom stem (scape). Several blue-green or green, narrow, strap-shaped leaves arise from the light bulb. The vegetable stem bears a solitary rose, but sometimes a cluster of bouquets (umbel). The blooms, that are conspicuous and white or yellow usually, both or seldom green sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an exterior ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical designed corona. The blooms may hang down (pendent), or be erect. You will discover six pollen bearing stamens bordering a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The fruit includes a dried up capsule that splits (dehisces) liberating numerous black seed products.
The bulb lays dormant following the leaves and rose stem die back and has contractile roots that move it down further in to the soil. The blossom stem and leaves form in the bulb, to emerge the next season. Most varieties are dormant from summer months to past due winter, flowering in the springtime, though a few varieties are fall flowering.
