Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plant life 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 with a cup- or trumpet-shaped corona. The plants are usually white or yellow (orange or pink in garden kinds), with either standard or contrasting colored tepals and corona.
Narcissus were popular in historic civilisation, both medicinally and botanically, but formally identified by Linnaeus in his Varieties Plantarum (1753). The genus is generally thought to have about ten areas with roughly 50 species. The amount of species has assorted, depending on how they are grouped, a consequence of to similarity between hybridization and types. The genus arose some time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise origins of the true name Narcissus is unidentified, but it is associated with a Greek term for intoxicated (narcotic) and the misconception of the youth of this name who fell deeply in love with his own representation. The English word 'daffodil' is apparently derived from "asphodel", with which it was compared commonly.
The kinds are indigenous to meadows and woods in southern Europe and North Africa with a center of variety in the American Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were introduced into the Far East prior to the tenth century. Narcissi tend to be long-lived bulbs, which propagate by division, but are insect-pollinated also. Known pests, disorders and diseases include viruses, fungi, the larvae of flies, nematodes and mites. 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 initial times, but became increasingly popular in Europe after the 16th hundred years and by the late 19th hundred years were an important commercial crop centred mostly on holland. Narcissi are popular as trim blooms so that ornamental crops 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 categorized into divisions, covering a variety of shapes and colours. Like other members of the 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 utilization in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in books and artwork, narcissi are associated with a true number of themes in several cultures, ranging from loss of life to fortune, and as icons of spring and coil. The daffodil is the countrywide flower of Wales and the icon of cancers charities in many countries. The looks of the crazy 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 to a underground storage bulb. They regrow in the next year from brown-skinned ovoid bulbs with pronounced necks, and reach levels of 5-80 cm with regards to the species. Dwarf types such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might develop as extra tall as 80 cm.
The crops are scapose, having an individual central leafless hollow flower stem (scape). Several blue-green or green, small, strap-shaped leaves arise from the light bulb. The seed stem bears a solitary flower, but occasionally a cluster of plants (umbel). The blossoms, which are usually conspicuous and white or yellow, sometimes both or almost never green, 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 disk to conical formed corona. The blooms may hang up down (pendent), or be erect. You can find six pollen bearing stamens surrounding a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The berry involves a dried capsule that splits (dehisces) launching numerous black seeds.
The bulb is dormant after the leaves and blossom stem die again and has contractile root base that draw it down further into the soil. The rose stem and leaves form in the bulb, to emerge the next season. Most species are dormant from warmer summer months to late winter, flowering in the spring, though a few species are fall flowering.
