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 used to describe all or some 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 generally white or yellowish (orange or red in garden kinds), with either even or contrasting colored tepals and corona.
Narcissus were well known in traditional civilisation, both and botanically medicinally, but formally identified by Linnaeus in his Types Plantarum (1753). The genus is generally thought to have about ten portions with around 50 species. The number of varieties has mixed, depending how they are labeled, a consequence of to similarity between hybridization and types. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The exact source of the name Narcissus is mysterious, but it is often associated with a Greek phrase for intoxicated (narcotic) and the myth of the children of this name who fell in love with his own reflection. The English term 'daffodil' is apparently produced from "asphodel", with which it was commonly likened.
The kinds are local to meadows and woods in southern Europe 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 have a tendency to be long-lived bulbs, which propagate by division, but are insect-pollinated also. Known pests, diseases and disorders include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have grown to be extinct, while some 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 late 19th century were an important commercial crop centred mainly on holland. Today narcissi are popular as trim blossoms so that ornamental plant life in private and general public gardens. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering a wide range of colours and shapes. Like other members of their family, narcissi produce 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 use within traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in books and art work, narcissi are associated with a true number of themes in several cultures, ranging from death to fortune, and as symbols of spring. The daffodil is the nationwide rose of Wales and the mark of malignancy charities in many countries. The looks of the outrageous flowers in springtime is associated with festivals 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 next calendar year 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 elevation of 5-8 cm, while Narcissus tazetta may grow as tall as 80 cm.
The crops are scapose, having a single central leafless hollow rose stem (scape). Several green or blue-green, slim, strap-shaped leaves arise from the light. The flower stem usually bears a solitary rose, but occasionally a cluster of blooms (umbel). The blooms, which can be usually conspicuous and white or yellowish, sometimes both or almost never renewable, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outer ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical designed corona. The blooms may suspend down (pendent), or be erect. You can find six pollen bearing stamens encircling a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The berries involves a dried up capsule that splits (dehisces) liberating numerous black seed products.
The bulb is dormant following the leaves and blossom stem die back again and has contractile roots that pull it down further into the soil. The bloom leaves and stem form in the light bulb, to emerge the following season. Most kinds are dormant from summer season to later winter, flowering in the planting season, though a few kinds are fall flowering.
