Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common names 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 a cup- or trumpet-shaped corona. The blossoms are usually white or yellowish (orange or red in garden types), with either uniform or contrasting coloured corona and tepals.
Narcissus were well known in traditional civilisation, both and botanically medicinally, but formally described by Linnaeus in his Kinds Plantarum (1753). The genus is normally thought to have about ten parts with about 50 species. The true variety of species has varied, depending on how they are grouped, a consequence of to similarity between hybridization and varieties. The genus arose time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The exact source of the real name Narcissus is unknown, but it is often associated with a Greek phrase for intoxicated (narcotic) and the myth of the youngsters of that name who fell in love with his own representation. The English word 'daffodil' appears to be produced from "asphodel", with which it was commonly compared.
The types are local to meadows and woods in southern European countries and North Africa with a center of diversity in the Western Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were introduced into the Far East prior to the tenth century. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are insect-pollinated also. 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 urbanisation and tourism.
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 mostly on holland. Today narcissi are popular as slice plants so that as ornamental vegetation in private and public gardens. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a wide range of colours and shapes. Like other members with 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 utilization in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in books and art work, narcissi are associated with a number of themes in various cultures, ranging from fatality to fortune, and as icons of planting season. The daffodil is the nationwide flower of Wales and the mark of cancer tumor charities in many countries. The looks of the outrageous flowers in spring and coil is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to an underground storage bulb. They regrow in the following 12 months from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm depending on species. Dwarf types such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might develop as high as 80 cm.
The crops are scapose, having an individual central leafless hollow bloom stem (scape). Several green or blue-green, small, strap-shaped leaves come up from the light. The plant stem usually bears a solitary blossom, but sometimes a cluster of plants (umbel). The blooms, which can be usually conspicuous and white or yellow, sometimes both or seldom inexperienced, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outer ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical molded corona. The plants may suspend down (pendent), or be erect. A couple of six pollen bearing stamens adjoining a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The super fruit consists of a dry out capsule that splits (dehisces) liberating numerous black seed products.
The bulb is situated dormant after the leaves and bloom stem die back and has contractile roots that pull it down further in to the soil. The bloom stem and leaves form in the light bulb, to emerge the following season. Most types are dormant from summer to late winter, flowering in the spring and coil, though a few kinds are fall flowering.
