Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common titles 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 with a cup- or trumpet-shaped corona. The flowers are usually white or yellow (orange or red in garden types), with either even or contrasting colored tepals and corona.
Narcissus were popular in old civilisation, both and botanically medicinally, but formally explained by Linnaeus in his Types Plantarum (1753). The genus is normally thought to have about ten areas with around 50 species. The amount of types has varied, depending on how they are categorized, due 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 undiscovered, but it is often linked to a Greek expression for intoxicated (narcotic) and the myth of the youth of this name who fell in love with his own representation. The English term 'daffodil' is apparently derived from "asphodel", with which it was compared commonly.
The types are local to meadows and woods in southern European countries and North Africa with a centre of diversity in the European Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were presented 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 also insect-pollinated. Known pests, disorders and diseases include viruses, fungi, the larvae of flies, mites and nematodes. 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 ever more popular in Europe after the 16th hundred years and by the later 19th hundred years were an important commercial crop centred mainly on the Netherlands. Today narcissi are popular as cut blossoms as ornamental crops 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 categorised into divisions, covering a variety of shapes and colours. Like other members of their family, narcissi produce a true 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 in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in art work and books, narcissi are associated with a true number of themes in several cultures, ranging from fatality to good fortune, and as symbols of planting season. The daffodil is the nationwide bloom of Wales and the mark of cancer charities in many countries. The appearance of the outrageous flowers in springtime is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering with an underground storage bulb. They regrow in the next 12 months from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm depending on species. Dwarf kinds such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may expand as high as 80 cm.
The plant life are scapose, having a single central leafless hollow flower stem (scape). Several green or blue-green, small, strap-shaped leaves occur from the light bulb. The place stem bears a solitary flower, but once in a while a cluster of blossoms (umbel). The blossoms, that happen to be conspicuous and white or yellowish usually, 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 exterior ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The blossoms may suspend down (pendent), or be erect. You will find six pollen bearing stamens adjoining a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The super fruit includes a dried up capsule that splits (dehisces) releasing numerous black seed products.
The bulb is placed dormant following the leaves and bloom stem die again and has contractile root base that move it down further into the soil. The bloom stem and leaves form in the bulb, to emerge the following season. Most kinds are dormant from warmer summer months to overdue winter, flowering in the spring and coil, though a few varieties are autumn flowering.
