Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common brands including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are being used to describe all or some members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted with a cup- or trumpet-shaped corona. The blossoms are generally white or yellow (orange or green in garden types), with either even or contrasting coloured tepals and corona.
Narcissus were popular in ancient civilisation, both and botanically medicinally, but formally referred to by Linnaeus in his Species Plantarum (1753). The genus is generally thought to have about ten areas with around 50 species. The true number of types has mixed, depending about how they are labeled, credited to similarity between species and hybridization. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact origin of the real name Narcissus is unfamiliar, but it is associated with a Greek word for intoxicated (narcotic) and the myth of the young ones of that name who fell in love with his own representation. The English term 'daffodil' appears to be derived from "asphodel", with which it was commonly likened.
The types are local to meadows and woods in southern European countries and North Africa with a middle of variety in the Traditional western Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were released in to the ASIA to the tenth hundred years prior. Narcissi tend 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 tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe following the 16th hundred years and by the overdue 19th hundred years were an important commercial crop centred mostly on the Netherlands. Narcissi are popular as slash blossoms so that ornamental plants in private and open public gardens today. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering a variety of colours and shapes. Like other members with 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 utilization in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in art work and books, narcissi are associated with a number of themes in various cultures, ranging from loss of life to fortune, and as icons of spring. The daffodil is the national rose of Wales and the sign of cancers charities in many countries. The looks of the crazy flowers in springtime is associated with festivals 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 next calendar year from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm with respect to the species. Dwarf varieties such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might grow as large as 80 cm.
The plant life are scapose, having a single central leafless hollow bloom stem (scape). Several green or blue-green, small, strap-shaped leaves come up from the bulb. The seed stem bears a solitary bloom, but sometimes a cluster of flowers (umbel). The blossoms, that happen to be usually conspicuous and white or yellow, both or hardly ever green sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe 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 suspend down (pendent), or be erect. You will find six pollen bearing stamens surrounding a central style. The ovary is substandard (below the floral parts) consisting of three chambers (trilocular). The berry consists of a dry capsule that splits (dehisces) launching numerous black seeds.
The bulb is placed dormant after the leaves and rose stem die back and has contractile origins that draw it down further into the soil. The rose leaves and stem form in the light bulb, to emerge the following season. Most species are dormant from summer time to overdue winter, flowering in the spring, though a few kinds are fall flowering.
