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 being used to describe all or some members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by a cup- or trumpet-shaped corona. The flowers are usually white or yellowish (orange or red in garden types), with either even or contrasting coloured tepals and corona.
Narcissus were well known in old civilisation, both medicinally and botanically, but formally identified by Linnaeus in his Varieties Plantarum (1753). The genus is normally considered to have about ten parts with about 50 species. The true volume of varieties has varied, depending about how they are classified, a consequence of to similarity between hybridization and kinds. The genus arose some right amount of time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact origins of the real name Narcissus is unidentified, but it is linked to 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 word 'daffodil' is apparently derived from "asphodel", with which it was likened commonly.
The kinds are indigenous to meadows and woods in southern Europe and North Africa with a middle of diversity in the Traditional western Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were unveiled in to the ASIA to the tenth hundred years prior. Narcissi tend to be long-lived bulbs, which propagate by division, but are insect-pollinated also. Known pests, disorders and diseases include viruses, fungi, the larvae of flies, nematodes and mites. Some Narcissus species have become extinct, while others 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 hundred years and by the later 19th century were an important commercial crop centred generally on holland. Narcissi are popular as trim bouquets as ornamental crops 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 grouped into divisions, covering a wide range of shapes and colours. Like other members of these family, narcissi create a number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested accidentally. This property has been exploited for medicinal use within traditional healing and has led to 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 good fortune, and as icons of springtime. The daffodil is the countrywide flower of Wales and the symbol of cancers charities in many countries. The appearance of the outrageous flowers in spring is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to the underground storage bulb. They regrow in the next yr from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm with respect to the species. Dwarf types such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might increase as high as 80 cm.
The crops are scapose, having a single central leafless hollow bloom stem (scape). Several green or blue-green, thin, strap-shaped leaves occur from the light bulb. The flower stem usually bears a solitary bloom, but sometimes a cluster of blossoms (umbel). The flowers, which can be usually conspicuous and white or yellowish, 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 composed of six tepals (undifferentiated sepals and petals), and a central disc to conical formed corona. The plants may hang up down (pendent), or be erect. You can find six pollen bearing stamens adjoining a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The berries consists of a dried out capsule that splits (dehisces) liberating numerous black seed products.
The bulb is situated dormant after the leaves and flower stem die back and has contractile roots that take it down further in to the soil. The bloom leaves and stem form in the bulb, to emerge the following season. Most kinds are dormant from summer time to later winter, flowering in the planting season, though a few kinds are fall months flowering.
