Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common labels 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 a cup- or trumpet-shaped corona. The plants are generally white or yellowish (orange or green in garden kinds), with either uniform or contrasting colored tepals and corona.
Narcissus were popular in historic civilisation, both and botanically medicinally, but formally explained by Linnaeus in his Varieties Plantarum (1753). The genus is generally thought to have about ten portions with approximately 50 species. The true quantity of kinds has varied, depending about how they are labeled, scheduled to similarity between kinds and hybridization. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise origin of the true name Narcissus is mysterious, but it is often linked to a Greek term for intoxicated (narcotic) and the misconception of the youngsters of that name who fell in love with his own reflection. The English word 'daffodil' appears to be produced from "asphodel", with which it was likened commonly.
The species are native to meadows and woods in southern European countries and North Africa with a center of variety in the Western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild 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, mites and nematodes. 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 initial times, but became increasingly popular in Europe following the 16th century and by the later 19th century were an important commercial crop centred mainly on holland. Narcissi are popular as cut bouquets and since 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 categorised into divisions, covering a variety of shapes and colours. Like other members of the 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 treatment of Alzheimer's dementia. Long celebrated in books and skill, narcissi are associated with a true number of themes in different cultures, ranging from death to fortune, and as symbols of planting season. The daffodil is the national flower of Wales and the symbol of tumors charities in many countries. The looks 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 back after flowering with an underground storage light bulb. They regrow in the next year from brown-skinned ovoid bulbs with pronounced necks, and reach levels of 5-80 cm depending on the species. Dwarf species such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may expand as extra tall as 80 cm.
The plant life are scapose, having a single central leafless hollow flower stem (scape). Several blue-green or green, small, strap-shaped leaves arise from the light bulb. The place stem usually bears a solitary bloom, but sometimes a cluster of bouquets (umbel). The blossoms, which can be 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 outside ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical shaped corona. The bouquets may hang down (pendent), or be erect. You will find six pollen bearing stamens adjoining a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The fruits consists of a dried up capsule that splits (dehisces) launching numerous black seeds.
The bulb is dormant following the leaves and bloom stem die back and has contractile root base that yank it down further into the soil. The blossom leaves and stem form in the light bulb, to emerge the next season. Most types are dormant from summer months to overdue winter, flowering in the spring and coil, though a few types are fall flowering.
