Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plants 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 by a cup- or trumpet-shaped corona. The flowers are generally white or yellow (orange or pink in garden kinds), with either uniform or contrasting colored corona and tepals.
Narcissus were well known in historic civilisation, both and botanically medicinally, but formally explained by Linnaeus in his Types Plantarum (1753). The genus is generally thought to have about ten parts with roughly 50 species. The true quantity of kinds has varied, depending on 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 precise source of the real name Narcissus is unidentified, but it is often associated with a Greek phrase for intoxicated (narcotic) and the misconception of the junior of this name who fell in love with his own reflection. The English expression 'daffodil' is apparently produced from "asphodel", with which it was commonly likened.
The varieties are native to meadows and woods in southern European countries and North Africa with a center of variety in the Traditional western Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were introduced in to the Far East before the tenth century. Narcissi tend 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 become extinct, while others are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe after the 16th century and by the past due 19th century were an important commercial crop centred mostly on the Netherlands. Narcissi are popular as chop plants so when ornamental vegetation in private and general population gardens today. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering a wide range of shapes and colours. Like other members with their family, narcissi produce 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 used in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in artwork and books, narcissi are associated with a number of themes in various cultures, ranging from loss of life to fortune, and as symbols of planting season. The daffodil is the nationwide bloom of Wales and the mark of tumor charities in many countries. The looks of the untamed flowers in spring is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering with an underground storage bulb. They regrow in the following calendar year from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf varieties such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may expand as high as 80 cm.
The plants 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 bulb. The plant stem bears a solitary blossom, but sometimes a cluster of flowers (umbel). The plants, which can be usually conspicuous and white or yellow, sometimes both or hardly ever inexperienced, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an exterior ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical molded corona. The plants may suspend down (pendent), or be erect. You can find six pollen bearing stamens surrounding a central style. The ovary is inferior (below the floral parts) consisting of three chambers (trilocular). The berries contains a dried up capsule that splits (dehisces) launching numerous black seeds.
The bulb lays dormant following the leaves and bloom stem die back again and has contractile roots that take it down further into the soil. The blossom stem and leaves form in the light, to emerge the next season. Most kinds are dormant from summer months to overdue winter, flowering in the springtime, though a few kinds are fall months flowering.
