Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common brands 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 blossoms are generally white or yellowish (orange or red in garden kinds), with either standard or contrasting coloured tepals and corona.
Narcissus were well known in traditional civilisation, both medicinally and botanically, but formally identified by Linnaeus in his Kinds Plantarum (1753). The genus is normally considered to have about ten parts with approximately 50 species. The true volume of types has assorted, depending how they are classified, a consequence of to similarity between hybridization and kinds. The genus arose some time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The exact origins of the name Narcissus is unknown, but it is often linked to a Greek term for intoxicated (narcotic) and the misconception of the youngsters of that name who fell in love with his own reflection. The English expression 'daffodil' appears to be derived from "asphodel", with which it was commonly likened.
The types are native to meadows and woods in southern Europe and North Africa with a center of variety in the Traditional 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, mites and nematodes. 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 initial times, but became ever more 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. Narcissi are popular as trim blossoms as ornamental crops in private and public gardens today. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a wide range of shapes and colours. 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 ingested unintentionally. This property has been exploited for medicinal use within traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in skill and books, narcissi are associated with a number of themes in various cultures, ranging from loss of life to fortune, and as symbols of springtime. The daffodil is the countrywide blossom of Wales and the mark of tumor charities in many countries. The looks of the outdoors flowers in planting season is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering to an underground storage light. They regrow in the following 12 months from brown-skinned ovoid 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 tall as 80 cm.
The plants are scapose, having a single central leafless hollow bloom stem (scape). Several blue-green or green, narrow, strap-shaped leaves occur from the bulb. The herb stem usually bears a solitary blossom, but occasionally a cluster of bouquets (umbel). The flowers, which are conspicuous and white or yellow usually, both or almost never renewable sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outside ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical designed corona. The blooms may hang down (pendent), or be erect. There are six pollen bearing stamens bordering a central style. The ovary is inferior (below the floral parts) consisting of three chambers (trilocular). The fruits consists of a dried up capsule that splits (dehisces) launching numerous black seed products.
The bulb sits dormant following the leaves and flower stem die back and has contractile origins that draw it down further in to the soil. The bloom stem and leaves form in the bulb, to emerge the next season. Most types are dormant from summer season to past due winter, flowering in the springtime, though a few varieties are fall months flowering.
