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 members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by a cup- or trumpet-shaped corona. The plants are generally white or yellowish (orange or red in garden kinds), with either uniform or contrasting colored corona and tepals.
Narcissus were well known in historical civilisation, both and botanically medicinally, but formally detailed by Linnaeus in his Varieties Plantarum (1753). The genus is generally considered to have about ten parts with about 50 species. The true volume of types has assorted, depending about how they are labeled, due to similarity between hybridization and kinds. The genus arose some right amount of time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact origins of the real name Narcissus is anonymous, but it is associated with a Greek expression for intoxicated (narcotic) and the myth of the junior of that name who fell deeply in love with his own reflection. The English word 'daffodil' appears to be derived from "asphodel", with which it was likened commonly.
The types are native to meadows and woods in southern Europe and North Africa with a center of variety in the Western 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, diseases and disorders include viruses, fungi, the larvae of flies, nematodes and mites. Some Narcissus species have become extinct, while others are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the initial times, but became ever more popular in Europe after the 16th hundred years and by the past due 19th hundred years were an important commercial crop centred mostly on holland. Today narcissi are popular as slice plants and as ornamental plants in private and general public gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering a wide range of colours and shapes. Like other members with their family, narcissi create a number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested accidentally. 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 art work and books, narcissi are associated with a true number of themes in various cultures, ranging from death to good fortune, and as symbols of planting season. The daffodil is the national blossom of Wales and the symbol of cancer tumor charities in many countries. The looks of the crazy 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 to an underground storage light bulb. They regrow in the next 12 months from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm with regards to the species. Dwarf species such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may grow as extra tall as 80 cm.
The vegetation are scapose, having an individual central leafless hollow blossom stem (scape). Several green or blue-green, narrow, strap-shaped leaves arise from the light bulb. The plant stem bears a solitary rose, but once in a while a cluster of blooms (umbel). The blooms, that happen to be conspicuous and white or yellowish usually, sometimes both or almost never renewable, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an external ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical formed corona. The blossoms may hang up down (pendent), or be erect. You will discover six pollen bearing stamens encircling a central style. The ovary is second-rate (below the floral parts) consisting of three chambers (trilocular). The berry involves a dry capsule that splits (dehisces) releasing numerous black seed products.
The bulb sits dormant after the leaves and bloom stem die back again and has contractile origins that move it down further in to the soil. The flower leaves and stem form in the light bulb, to emerge the next season. Most varieties are dormant from summer time to overdue winter, flowering in the spring, though a few species are autumn flowering.
