Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plants 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 by a cup- or trumpet-shaped corona. The blossoms are usually white or yellow (orange or pink in garden varieties), with either even or contrasting colored corona and tepals.
Narcissus were well known in ancient civilisation, both medicinally and botanically, but formally detailed by Linnaeus in his Species Plantarum (1753). The genus is generally thought to have about ten areas with around 50 species. The amount of kinds has mixed, depending about how they are categorized, due 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 regions of southwest Europe. The exact origins of the name Narcissus is unfamiliar, but it is linked to a Greek term for intoxicated (narcotic) and the myth of the junior of this name who fell in love with his own representation. The English term 'daffodil' is apparently derived from "asphodel", with which it was commonly likened.
The varieties are indigenous to meadows and woods in southern Europe and North Africa with a center of diversity in the Western Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were created into the Far East to the tenth hundred years prior. 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, mites and nematodes. Some Narcissus species have grown to be extinct, while others 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 century and by the later 19th hundred years were an important commercial crop centred mainly on the Netherlands. Today narcissi are popular as chop bouquets so when ornamental crops in private and public gardens. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering a variety 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 accidentally ingested. This property has been exploited for medicinal use within traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in books and art, narcissi are associated with a number of themes in different cultures, ranging from loss of life to good fortune, and as icons of planting season. The daffodil is the national flower of Wales and the image of cancer tumor charities in many countries. The appearance of the outrageous flowers in spring and coil is associated with celebrations 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 following time from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf types such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may develop as extra tall as 80 cm.
The crops are scapose, having a single central leafless hollow flower stem (scape). Several blue-green or green, slim, strap-shaped leaves happen from the light bulb. The plant stem bears a solitary bloom, but once in a while a cluster of blooms (umbel). The flowers, that happen to be conspicuous and white or yellowish usually, both or seldom renewable sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an external ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical shaped corona. The flowers may hang down (pendent), or be erect. You will find six pollen bearing stamens encompassing a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The fruit contains a dried capsule that splits (dehisces) launching numerous black seeds.
The bulb is dormant following the leaves and flower stem die back and has contractile origins that pull it down further in to the soil. The bloom stem and leaves form in the light, to emerge the following season. Most species are dormant from warmer summer months to later winter, flowering in the spring, though a few species are fall months flowering.
