Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common brands 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 with a cup- or trumpet-shaped corona. The flowers are generally white or yellow (orange or green in garden kinds), with either even or contrasting coloured corona and tepals.
Narcissus were popular in early civilisation, both medicinally and botanically, but formally detailed by Linnaeus in his Species Plantarum (1753). The genus is generally thought to have about ten portions with around 50 species. The true volume of varieties has mixed, depending how they are labeled, credited 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 origins of the name Narcissus is unfamiliar, but it is often associated with a Greek term for intoxicated (narcotic) and the myth of the youth 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 varieties are indigenous to meadows and woods in southern European countries and North Africa with a center of variety in the European Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were created into the Far East to the tenth hundred years prior. 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 some 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 after the 16th hundred years and by the past due 19th hundred years were an important commercial crop centred generally on the Netherlands. Narcissi are popular as chop flowers and as ornamental plants in private and open public gardens today. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering an array of colours and shapes. Like other members of their family, narcissi create a number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested inadvertently. This property has been exploited for medicinal use in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in literature and skill, narcissi are associated with a number of themes in several cultures, ranging from loss of life to fortune, and as symbols of springtime. The daffodil is the countrywide flower of Wales and the mark of cancers charities in many countries. The looks of the outrageous flowers in springtime is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to a underground storage light bulb. They regrow in the next calendar year from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm with respect to the species. Dwarf kinds such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may increase as extra tall as 80 cm.
The plant life are scapose, having an individual central leafless hollow rose stem (scape). Several green or blue-green, narrow, strap-shaped leaves arise from the light. The flower stem usually bears a solitary rose, but once in a while a cluster of blossoms (umbel). The bouquets, that happen to be usually conspicuous and white or yellowish, sometimes both or hardly ever renewable, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an external ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical shaped corona. The flowers may hang down (pendent), or be erect. You will discover six pollen bearing stamens bordering a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The berry contains a dry out capsule that splits (dehisces) releasing numerous black seeds.
The bulb is placed dormant following the leaves and flower stem die back again and has contractile roots that move it down further in to the soil. The bloom stem and leaves form in the bulb, to emerge the next season. Most species are dormant from summer time to later winter, flowering in the spring and coil, though a few species are autumn flowering.
