Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common titles 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 flowers are usually white or yellow (orange or pink in garden kinds), with either standard or contrasting coloured tepals and corona.
Narcissus were popular in historic civilisation, both medicinally and botanically, but formally explained by Linnaeus in his Kinds Plantarum (1753). The genus is generally considered to have about ten portions with around 50 species. The number of kinds has mixed, depending about how they are labeled, scheduled 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 regions of southwest Europe. The precise origin of the name Narcissus is mysterious, but it is associated with a Greek phrase for intoxicated (narcotic) and the myth of the youngsters of that name who fell in love with his own representation. The English term 'daffodil' is apparently produced from "asphodel", with which it was commonly compared.
The varieties are native to meadows and woods in southern European countries and North Africa with a middle of diversity in the European Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were introduced into the Far East before the tenth century. Narcissi tend 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, mites and nematodes. Some Narcissus species have grown to be extinct, while some are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became ever more popular in Europe after the 16th century and by the late 19th hundred years were an important commercial crop centred primarily on the Netherlands. Narcissi are popular as trim flowers and as ornamental plant life in private and general public gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering a variety of colours and shapes. Like other members of these family, narcissi create a true 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 used in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in art work and books, narcissi are associated with a true number of themes in various cultures, ranging from loss of life to fortune, and as icons of spring. The daffodil is the countrywide bloom of Wales and the mark of tumor charities in many countries. The looks of the wild flowers in planting season 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. They regrow in the following 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 level of 5-8 cm, while Narcissus tazetta may grow as large as 80 cm.
The vegetation are scapose, having a single central leafless hollow flower stem (scape). Several blue-green or green, thin, strap-shaped leaves arise from the light. The plant stem bears a solitary rose, but occasionally a cluster of bouquets (umbel). The plants, which are usually conspicuous and white or yellowish, sometimes both or almost never green, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outside ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical designed corona. The blossoms may hang down (pendent), or be erect. You will discover six pollen bearing stamens encircling a central style. The ovary is inferior (below the floral parts) consisting of three chambers (trilocular). The fruit includes a dried out capsule that splits (dehisces) launching numerous black seeds.
The bulb is dormant following the leaves and bloom stem die back again and has contractile roots that yank it down further into the soil. The bloom stem and leaves form in the light, to emerge the following season. Most kinds are dormant from summer season to later winter, flowering in the planting season, though a few types are autumn flowering.
