Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common labels 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 plants are usually white or yellowish (orange or red in garden kinds), with either uniform or contrasting coloured tepals and corona.
Narcissus were popular in old civilisation, both medicinally and botanically, but formally explained by Linnaeus in his Kinds Plantarum (1753). The genus is generally considered to have about ten parts with about 50 species. The true variety of types has mixed, depending about how they are labeled, due to similarity between species and hybridization. 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 real name Narcissus is anonymous, but it is often linked to a Greek term for intoxicated (narcotic) and the myth of the junior of that name who fell in love with his own reflection. The English term 'daffodil' is apparently derived from "asphodel", with which it was commonly compared.
The species are native to meadows and woods in southern Europe and North Africa with a middle of diversity in the Traditional western Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were introduced into the Far East to the tenth century prior. Narcissi have a tendency 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, nematodes and mites. 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 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 the Netherlands. Today narcissi are popular as slash blossoms as ornamental vegetation 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 colours and shapes. Like other members of the family, narcissi create a number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested unintentionally. This property has been exploited for medicinal used in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in skill and books, narcissi are associated with a true number of themes in various cultures, ranging from death to fortune, and as icons of spring and coil. The daffodil is the countrywide blossom of Wales and the image of tumors charities in many countries. The looks of the untamed flowers in planting season is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering to a underground storage light bulb. They regrow in the following time from brown-skinned ovoid bulbs with pronounced necks, and reach levels of 5-80 cm depending on the species. Dwarf varieties such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might grow as high as 80 cm.
The plants are scapose, having an individual central leafless hollow bloom stem (scape). Several blue-green or green, thin, strap-shaped leaves arise from the light. The plant stem usually bears a solitary rose, but sometimes a cluster of blooms (umbel). The blossoms, which can be usually conspicuous and white or yellowish, both or hardly ever renewable sometimes, contain 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 disk to conical shaped corona. The bouquets may suspend down (pendent), or be erect. You will find six pollen bearing stamens encircling a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The berries contains a dry out capsule that splits (dehisces) releasing numerous black seeds.
The bulb is dormant after the leaves and flower stem die back again and has contractile origins that move it down further into the soil. The blossom leaves and stem form in the light, to emerge the following season. Most species are dormant from summertime to overdue winter, flowering in the planting season, though a few kinds are fall flowering.
