Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common brands 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 with a cup- or trumpet-shaped corona. The blooms are generally white or yellowish (orange or pink in garden varieties), with either even or contrasting coloured corona and tepals.
Narcissus were well known in ancient civilisation, both and botanically medicinally, but formally referred to by Linnaeus in his Species Plantarum (1753). The genus is normally considered to have about ten areas with roughly 50 species. The number of species has assorted, depending on how they are grouped, anticipated to similarity between types and hybridization. The genus arose some right time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The exact origin of the true name Narcissus is unidentified, but it is often linked to a Greek expression for intoxicated (narcotic) and the misconception of the children of that name who fell deeply in love with his own reflection. The English expression 'daffodil' is apparently derived from "asphodel", with which it was likened commonly.
The species are local to meadows and woods in southern Europe and North Africa with a centre of variety in the European Mediterranean, particularly the Iberian peninsula. Both cultivated and wild 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 insect-pollinated also. Known pests, diseases and disorders include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have become extinct, while others are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became ever more popular in Europe following the 16th hundred years and by the late 19th century were an important commercial crop centred mainly on the Netherlands. Today narcissi are popular as chop bouquets so when 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 categorised into divisions, covering a variety 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 in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in fine art and books, narcissi are associated with a number of themes in different cultures, ranging from loss of life to fortune, and as icons of spring and coil. The daffodil is the national bloom of Wales and the sign of cancers charities in many countries. The appearance of the outrageous flowers in spring and coil is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering with an underground storage light bulb. They regrow in the following yr from brown-skinned ovoid bulbs with pronounced necks, and reach levels of 5-80 cm depending on species. Dwarf kinds such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may develop as large as 80 cm.
The plant life are scapose, having a single central leafless hollow blossom stem (scape). Several green or blue-green, slim, strap-shaped leaves come up from the light bulb. The herb stem usually bears a solitary bloom, but occasionally a cluster of blooms (umbel). The bouquets, that are conspicuous and white or yellow usually, both or almost never green sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outer ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical formed corona. The bouquets may hang up down (pendent), or be erect. You will find six pollen bearing stamens surrounding a central style. The ovary is substandard (below the floral parts) consisting of three chambers (trilocular). The berry includes a dry capsule that splits (dehisces) liberating numerous black seed products.
The bulb lays dormant following the leaves and bloom stem die back again and has contractile root base that move it down further into the soil. The rose stem and leaves form in the light, to emerge the following season. Most varieties are dormant from summer time to overdue winter, flowering in the springtime, though a few species are fall flowering.
