Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common names including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are 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 usually white or yellowish (orange or red in garden kinds), with either even or contrasting coloured corona and tepals.
Narcissus were popular in old civilisation, both and botanically medicinally, but formally identified by Linnaeus in his Types Plantarum (1753). The genus is normally thought to have about ten portions with around 50 species. The true number of types has assorted, depending on how they are categorized, anticipated to similarity between types 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 name Narcissus is undiscovered, but it is linked to a Greek phrase for intoxicated (narcotic) and the misconception of the junior of this name who fell in love with his own representation. The English word 'daffodil' is apparently derived from "asphodel", with which it was commonly compared.
The species are local to meadows and woods in southern European countries and North Africa with a center of diversity in the Traditional western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild 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, disorders and diseases include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have become extinct, while some 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 generally on holland. Today narcissi are popular as slice blooms so that ornamental plant life 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 colours and shapes. 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 accidentally ingested. This property has been exploited for medicinal utilization in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in books and fine art, narcissi are associated with a true number of themes in different cultures, ranging from death to fortune, and as symbols of planting season. The daffodil is the nationwide rose of Wales and the mark of cancers charities in many countries. The appearance of the untamed flowers in planting season 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 bulb. They regrow in the following time from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm depending on species. Dwarf types such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may develop as high as 80 cm.
The plant life are scapose, having a single central leafless hollow rose stem (scape). Several green or blue-green, small, strap-shaped leaves occur from the light. The herb stem usually bears a solitary blossom, but once in a while a cluster of plants (umbel). The blooms, which are usually conspicuous and white or yellow, both or almost never inexperienced sometimes, 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 molded corona. The blooms may hang down (pendent), or be erect. You will find six pollen bearing stamens encircling a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The fruits includes a dried capsule that splits (dehisces) releasing numerous black seed products.
The bulb is situated dormant following the leaves and bloom stem die again and has contractile root base that draw it down further in to the soil. The blossom leaves and stem form in the light bulb, to emerge the next season. Most varieties are dormant from summer months to overdue winter, flowering in the spring and coil, though a few species are fall flowering.
