Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial crops 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 the cup- or trumpet-shaped corona. The bouquets are generally white or yellowish (orange or pink in garden types), with either even or contrasting colored tepals and corona.
Narcissus were popular in old civilisation, both medicinally and botanically, but formally detailed by Linnaeus in his Kinds Plantarum (1753). The genus is normally thought to have about ten sections with approximately 50 species. The true number of varieties has mixed, depending about how they are categorised, anticipated to similarity between species and hybridization. The genus arose some right time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact origins of the true name Narcissus is unfamiliar, but it is often linked to a Greek expression for intoxicated (narcotic) and the misconception of the youngsters of this name who fell in love with his own representation. The English expression 'daffodil' is apparently produced from "asphodel", with which it was commonly likened.
The varieties are local to meadows and woods in southern Europe and North Africa with a center of diversity in the Traditional western Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were released in to the ASIA to the tenth hundred years prior. Narcissi have a tendency 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, 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 ever more popular in Europe following the 16th century and by the later 19th century were an important commercial crop centred mainly on the Netherlands. Today narcissi are popular as slash flowers as ornamental vegetation in private and open public gardens. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a variety of colours and shapes. Like other members of the family, narcissi produce a true number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested inadvertently. This property has been exploited for medicinal use in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in books and skill, narcissi are associated with a true number of themes in various cultures, ranging from loss of life to fortune, and as icons of spring and coil. The daffodil is the countrywide rose of Wales and the image of cancer tumor charities in many countries. The appearance of the wild flowers in springtime is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to a underground storage light bulb. They regrow in the following season from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm with regards to the species. Dwarf types such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may grow as tall as 80 cm.
The plants are scapose, having an individual central leafless hollow flower stem (scape). Several green or blue-green, narrow, strap-shaped leaves come up from the light bulb. The herb stem usually bears a solitary flower, but sometimes a cluster of blossoms (umbel). The blossoms, that are usually conspicuous and white or yellow, both or rarely green sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an exterior ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical molded corona. The bouquets may suspend down (pendent), or be erect. You will find six pollen bearing stamens adjoining a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The fruits involves a dried capsule that splits (dehisces) liberating numerous black seed products.
The bulb is dormant after the leaves and bloom stem die back again and has contractile root base that draw it down further in to the soil. The blossom stem and leaves form in the bulb, to emerge the following season. Most kinds are dormant from summer months to overdue winter, flowering in the spring and coil, though a few kinds are fall months flowering.
