Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common brands 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 bouquets are generally white or yellow (orange or pink in garden kinds), with either even or contrasting coloured tepals and corona.
Narcissus were popular in ancient civilisation, both and botanically medicinally, but formally identified by Linnaeus in his Varieties Plantarum (1753). The genus is generally considered to have about ten parts with approximately 50 species. The amount of kinds has varied, depending on how they are categorised, thanks to similarity between hybridization and kinds. The genus arose time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise source of the true name Narcissus is unknown, but it is often linked to a Greek expression for intoxicated (narcotic) and the misconception of the children of that name who fell in love with his own reflection. The English expression 'daffodil' is apparently produced from "asphodel", with which it was compared commonly.
The types are local to meadows and woods in southern Europe and North Africa with a centre of diversity in the Traditional western Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were unveiled in to the Far East 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, diseases and disorders include viruses, fungi, the larvae of flies, nematodes and mites. Some Narcissus species have become extinct, while others are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe after the 16th hundred years and by the overdue 19th century were an important commercial crop centred mainly on the Netherlands. Today narcissi are popular as trim blooms so that as ornamental plant life 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 classified into divisions, covering a wide range of shapes and colours. 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 accidentally. 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 books and fine art, narcissi are associated with a true number of themes in various cultures, ranging from death to good fortune, and as symbols of spring and coil. The daffodil is the countrywide flower of Wales and the image of cancers 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 year from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf kinds such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may develop as large as 80 cm.
The crops are scapose, having a single central leafless hollow blossom stem (scape). Several blue-green or green, slim, strap-shaped leaves happen from the light. The herb stem bears a solitary blossom, but sometimes a cluster of plants (umbel). The bouquets, which are usually conspicuous and white or yellowish, sometimes both or seldom renewable, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outside ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical designed corona. The flowers may suspend down (pendent), or be erect. You can find six pollen bearing stamens bordering a central style. The ovary is second-rate (below the floral parts) consisting of three chambers (trilocular). The fruits involves a dried capsule that splits (dehisces) liberating numerous black seeds.
The bulb is dormant following the leaves and rose stem die again and has contractile root base that move it down further in to the soil. The flower leaves and stem form in the light bulb, to emerge the following season. Most types are dormant from summer time to later winter, flowering in the planting season, though a few species are autumn flowering.
