Narcissus /n?:r's?s?s/ is a genus of predominantly 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 members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by the cup- or trumpet-shaped corona. The blooms are usually white or yellowish (orange or pink in garden varieties), with either even or contrasting colored tepals and corona.
Narcissus were popular in historical civilisation, both medicinally and botanically, but formally defined by Linnaeus in his Types Plantarum (1753). The genus is normally thought to have about ten areas with about 50 species. The number of kinds has assorted, depending how they are categorized, anticipated to similarity between kinds and hybridization. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise origin of the real name Narcissus is unknown, but it is associated with a Greek word for intoxicated (narcotic) and the myth of the junior of that name who fell deeply in love with his own reflection. The English expression 'daffodil' appears to be produced from "asphodel", with which it was compared commonly.
The varieties are native to meadows and woods in southern Europe and North Africa with a center of diversity in the Western Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were introduced into the Far East before the tenth century. Narcissi tend 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 century and by the overdue 19th century were an important commercial crop centred primarily on holland. Today narcissi are popular as chop flowers so that ornamental plants in private and public gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering a variety of colours and shapes. Like other members of these family, narcissi produce a 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 used in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in literature and art, narcissi are associated with a number of themes in various cultures, ranging from loss of life to good fortune, and as symbols of planting season. The daffodil is the national blossom of Wales and the image of tumors 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 bulb. They regrow in the next 12 months from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf species such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might grow as high as 80 cm.
The plants are scapose, having an individual central leafless hollow rose stem (scape). Several green or blue-green, narrow, strap-shaped leaves arise from the light bulb. The herb stem usually bears a solitary blossom, but occasionally a cluster of blooms (umbel). The blooms, that happen to be conspicuous and white or yellow usually, sometimes both or seldom inexperienced, 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 disk to conical designed corona. The blossoms may hang down (pendent), or be erect. You will find six pollen bearing stamens bordering a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The berry consists of a dry out capsule that splits (dehisces) liberating numerous black seed products.
The bulb is situated dormant following the leaves and flower stem die back again and has contractile root base that yank it down further into the soil. The bloom leaves and stem form in the light, to emerge the following season. Most types are dormant from summer season to past due winter, flowering in the spring, though a few species are fall months flowering.
