Narcissus /n?:r's?s?s/ is a genus of mostly 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 members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by the cup- or trumpet-shaped corona. The bouquets are usually white or yellow (orange or green in garden varieties), with either uniform or contrasting colored tepals and corona.
Narcissus were popular in historical civilisation, both and botanically medicinally, but formally defined by Linnaeus in his Kinds Plantarum (1753). The genus is generally considered to have about ten sections with around 50 species. The amount of species has assorted, depending about how they are grouped, credited to similarity between varieties and hybridization. The genus arose time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact origins of the true name Narcissus is unidentified, but it is often linked to a Greek term for intoxicated (narcotic) and the misconception of the junior of this name who fell deeply in love with his own representation. The English expression 'daffodil' is apparently produced from "asphodel", with which it was commonly likened.
The kinds are local to meadows and woods in southern Europe and North Africa with a middle of diversity in the European Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were presented in to 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 become extinct, while some are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe following the 16th century and by the past due 19th hundred years were an important commercial crop centred mainly on the Netherlands. Narcissi are popular as lower blooms so that as ornamental vegetation in private and open public gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a wide range of shapes and colours. Like other members of their family, narcissi produce 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 use in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in literature and art work, narcissi are associated with a true number of themes in several cultures, ranging from loss of life to good fortune, and as icons of spring and coil. The daffodil is the countrywide blossom of Wales and the symbol of cancer charities in many countries. The appearance of the untamed 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 bulb. They regrow in the next calendar year from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm depending on species. Dwarf kinds such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may develop as large as 80 cm.
The plants are scapose, having a single central leafless hollow flower stem (scape). Several blue-green or green, small, strap-shaped leaves occur from the light bulb. The place stem usually bears a solitary bloom, but sometimes a cluster of blossoms (umbel). The flowers, that happen to be conspicuous and white or yellowish usually, both or seldom inexperienced sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outside ring composed 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 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 up capsule that splits (dehisces) liberating numerous black seed products.
The bulb is dormant following the leaves and bloom stem die back again and has contractile origins that pull it down further in to the soil. The rose leaves and stem form in the light, to emerge the next season. Most varieties are dormant from warmer summer months to late winter, flowering in the planting season, though a few varieties are fall months flowering.
