Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plants 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 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 varieties), with either standard or contrasting coloured corona and tepals.
Narcissus were popular in historic civilisation, both and botanically medicinally, but formally referred to by Linnaeus in his Kinds Plantarum (1753). The genus is normally considered to have about ten parts with about 50 species. The true range of varieties has assorted, depending how they are grouped, a consequence of to similarity between hybridization and types. The genus arose some right amount of time 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 anonymous, but it is often linked to a Greek expression for intoxicated (narcotic) and the myth of the junior of this name who fell in love with his own reflection. The English word 'daffodil' appears to be derived from "asphodel", with which it was commonly compared.
The kinds are native to meadows and woods in southern Europe and North Africa with a center of diversity in the European Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were launched into the Far East to the tenth hundred years prior. Narcissi have a tendency 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 grown to be extinct, while others are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe after the 16th hundred years and by the past due 19th hundred years were an important commercial crop centred mainly on holland. Today narcissi are popular as chop bouquets so when ornamental vegetation in private and public gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a variety of shapes and colours. Like other members of these family, narcissi create 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 treatment of Alzheimer's dementia. Long celebrated in books and art, narcissi are associated with a true number of themes in several cultures, ranging from death to good fortune, and as symbols of spring and coil. The daffodil is the nationwide blossom of Wales and the mark of cancers charities in many countries. The appearance of the crazy flowers in spring and coil is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to the underground storage light. They regrow in the next time from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm with respect to the species. Dwarf types such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might develop as high as 80 cm.
The crops are scapose, having a single central leafless hollow blossom stem (scape). Several blue-green or green, thin, strap-shaped leaves arise from the light. The vegetable stem bears a solitary flower, but sometimes a cluster of blossoms (umbel). The blossoms, which can be usually conspicuous and white or yellowish, both or almost never renewable sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outer ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical molded corona. The flowers may hang down (pendent), or be erect. You will discover six pollen bearing stamens encircling a central style. The ovary is inferior (below the floral parts) consisting of three chambers (trilocular). The fruits contains a dried capsule that splits (dehisces) releasing numerous black seed products.
The bulb is dormant following the leaves and rose stem die again and has contractile origins that take it down further in to the soil. The flower leaves and stem form in the light, to emerge the following season. Most types are dormant from summer time to late winter, flowering in the spring and coil, though a few varieties are fall flowering.
