Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common titles including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are used to describe all or some known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by the cup- or trumpet-shaped corona. The bouquets are usually white or yellow (orange or green in garden varieties), with either even or contrasting colored corona and tepals.
Narcissus were well known in early civilisation, both medicinally and botanically, but formally explained by Linnaeus in his Types Plantarum (1753). The genus is generally considered to have about ten parts with approximately 50 species. The true volume of kinds has mixed, depending how they are grouped, as a consequence 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 areas of southwest Europe. The exact origin of the real name Narcissus is undiscovered, but it is linked to a Greek term for intoxicated (narcotic) and the misconception of the children of this name who fell deeply in love with his own representation. The English expression 'daffodil' is apparently derived from "asphodel", with which it was commonly compared.
The types are indigenous to meadows and woods in southern Europe and North Africa with a center of diversity in the Western Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were created into the Far East to the tenth century prior. 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 become 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 following the 16th hundred years and by the past due 19th century were an important commercial crop centred generally on the Netherlands. Narcissi are popular as cut plants as ornamental plants in private and public gardens today. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a wide range of colours and shapes. Like other members with 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 fine art and books, narcissi are associated with a number of themes in various cultures, ranging from death to fortune, and as icons of spring. The daffodil is the countrywide flower of Wales and the icon of tumors charities in many countries. The appearance of the outrageous flowers in spring is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering to an underground storage light bulb. They regrow in the next year from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm depending on species. Dwarf varieties such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might expand as large as 80 cm.
The plant life are scapose, having an individual central leafless hollow blossom stem (scape). Several green or blue-green, thin, strap-shaped leaves occur from the bulb. The place stem usually bears a solitary bloom, but once in a while a cluster of blossoms (umbel). The blooms, which can be usually conspicuous and white or yellow, 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 outer ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical formed corona. The blooms may hang down (pendent), or be erect. You will discover six pollen bearing stamens encircling a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The fruits involves a dry capsule that splits (dehisces) releasing numerous black seeds.
The bulb is dormant after the leaves and blossom stem die back again and has contractile roots that take it down further in to the soil. The flower leaves and stem form in the light, to emerge the following season. Most types are dormant from summer to later winter, flowering in the spring and coil, though a few kinds are autumn flowering.
