Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common labels 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 the cup- or trumpet-shaped corona. The blooms are usually white or yellowish (orange or green in garden kinds), with either even or contrasting coloured tepals and corona.
Narcissus were popular in old civilisation, both medicinally and botanically, but formally explained by Linnaeus in his Varieties Plantarum (1753). The genus is generally considered to have about ten portions with roughly 50 species. The number of types has varied, depending on how they are categorized, credited to similarity between types and hybridization. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise origin of the name Narcissus is anonymous, but it is often linked to a Greek phrase for intoxicated (narcotic) and the myth of the youngsters of this name who fell deeply in love with his own reflection. The English expression 'daffodil' appears to be derived from "asphodel", with which it was compared commonly.
The species are native to meadows and woods in southern Europe and North Africa with a middle of diversity in the Western Mediterranean, the Iberian peninsula particularly. 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 become extinct, while others are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe after the 16th hundred years and by the past due 19th hundred years were an important commercial crop centred mostly on holland. Today narcissi are popular as slice flowers and as ornamental plants in private and general population gardens. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering a variety of shapes and colours. 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 treatment of Alzheimer's dementia. Long celebrated in art and books, narcissi are associated with a number of themes in various cultures, ranging from fatality to fortune, and as symbols of spring. The daffodil is the national blossom of Wales and the mark of cancers charities in many countries. The looks of the outdoors flowers in springtime is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering with an underground storage light. They regrow in the following calendar year from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm with respect to the species. Dwarf varieties such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may expand as extra tall as 80 cm.
The vegetation are scapose, having an individual central leafless hollow flower stem (scape). Several blue-green or green, small, strap-shaped leaves happen from the light. The flower stem bears a solitary flower, but occasionally a cluster of bouquets (umbel). The blooms, which are usually conspicuous and white or yellow, both or seldom inexperienced sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outside ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The blossoms may hang up down (pendent), or be erect. You will discover six pollen bearing stamens surrounding a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The berries involves a dried out capsule that splits (dehisces) liberating numerous black seed products.
The bulb is situated dormant after the leaves and flower stem die back again and has contractile roots that pull it down further in to the soil. The blossom stem and leaves form in the light bulb, to emerge the next season. Most types are dormant from summertime to overdue winter, flowering in the spring and coil, though a few species are autumn flowering.
