Narcissus /n?:r's?s?s/ is a genus of predominantly 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 way of a cup- or trumpet-shaped corona. The plants are usually white or yellowish (orange or pink in garden types), with either standard or contrasting colored corona and tepals.
Narcissus were well known in old civilisation, both medicinally and botanically, but formally identified by Linnaeus in his Species Plantarum (1753). The genus is generally thought to have about ten areas with approximately 50 species. The true number of species has mixed, depending on how they are classified, scheduled 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 precise source of the name Narcissus is anonymous, but it is often associated with a Greek word for intoxicated (narcotic) and the misconception of the youngsters of this name who fell in love with his own representation. The English term 'daffodil' appears to be produced from "asphodel", with which it was commonly compared.
The types are native to meadows and woods in southern European countries and North Africa with a center of diversity in the Western Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were launched 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, diseases and disorders include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have become 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 following the 16th century and by the late 19th hundred years were an important commercial crop centred generally on holland. Narcissi are popular as slash bouquets and since ornamental vegetation in private and general public gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a wide range of shapes and colours. 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 ingested unintentionally. This property has been exploited for medicinal used in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in books and fine art, narcissi are associated with a number of themes in different cultures, ranging from fatality to fortune, and as symbols of planting season. The daffodil is the countrywide bloom of Wales and the symbol of malignancy charities in many countries. The appearance of the crazy flowers in spring is associated with celebrations 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 next yr from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm depending on the species. Dwarf kinds such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may expand as high as 80 cm.
The plants are scapose, having a single central leafless hollow bloom stem (scape). Several blue-green or green, small, strap-shaped leaves happen from the bulb. The flower stem usually bears a solitary flower, but occasionally a cluster of flowers (umbel). The bouquets, that are usually conspicuous and white or yellow, sometimes both or hardly ever inexperienced, 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 disc 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 second-rate (below the floral parts) comprising three chambers (trilocular). The fruits includes a dried capsule that splits (dehisces) launching numerous black seeds.
The bulb is placed dormant after the leaves and flower stem die back again and has contractile root base that pull it down further in to the soil. The flower stem and leaves form in the bulb, to emerge the next season. Most types are dormant from summertime to past due winter, flowering in the spring, though a few kinds are fall flowering.
