Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common names including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are being used to describe all or some known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted with a cup- or trumpet-shaped corona. The blossoms are usually white or yellowish (orange or red in garden kinds), with either even or contrasting colored tepals and corona.
Narcissus were popular in ancient civilisation, both medicinally and botanically, but formally described by Linnaeus in his Varieties Plantarum (1753). The genus is generally thought to have about ten parts with roughly 50 species. The true quantity of species has assorted, depending how they are classified, scheduled to similarity between kinds and hybridization. The genus arose some right time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise source of the name Narcissus is unidentified, but it is associated with a Greek expression for intoxicated (narcotic) and the misconception of the young ones of that name who fell in love with his own reflection. The English term 'daffodil' is apparently produced from "asphodel", with which it was likened commonly.
The types are native to meadows and woods in southern Europe and North Africa with a centre of variety in the American Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were released into the Far East to the tenth century 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 grown to be extinct, while some are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became ever more popular in Europe following the 16th century and by the later 19th century were an important commercial crop centred generally on the Netherlands. Today narcissi are popular as slash blossoms and since ornamental crops in private and general population gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering a wide range of shapes and colours. Like other members with their family, narcissi create a 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 treating Alzheimer's dementia. Long celebrated in literature and artwork, narcissi are associated with a number of themes in different cultures, ranging from fatality to fortune, and as icons of springtime. The daffodil is the countrywide bloom of Wales and the icon of tumor charities in many countries. The appearance of the outdoors flowers in spring and coil is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering for an underground storage light bulb. They regrow in the next yr from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm with regards to the species. Dwarf kinds such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might increase as large as 80 cm.
The plant life are scapose, having an individual central leafless hollow rose stem (scape). Several blue-green or green, small, strap-shaped leaves arise from the light bulb. The flower stem usually bears a solitary blossom, but occasionally a cluster of bouquets (umbel). The flowers, which are usually conspicuous and white or yellow, sometimes both or seldom renewable, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an external ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical shaped corona. The blossoms may suspend down (pendent), or be erect. A couple of six pollen bearing stamens bordering a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The fruits contains a dry out capsule that splits (dehisces) releasing numerous black seed products.
The bulb is dormant following the leaves and blossom stem die back again and has contractile root base that yank it down further in to the soil. The rose stem and leaves form in the light, to emerge the next season. Most varieties are dormant from warmer summer months to late winter, flowering in the springtime, though a few species are fall months flowering.
