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 the cup- or trumpet-shaped corona. The blooms are generally white or yellow (orange or green in garden types), with either even or contrasting colored tepals and corona.
Narcissus were well known in old civilisation, both medicinally and botanically, but formally detailed by Linnaeus in his Kinds Plantarum (1753). The genus is normally thought to have about ten portions with roughly 50 species. The true number of species has assorted, depending about how they are classified, credited to similarity between types and hybridization. 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 source of the real name Narcissus is anonymous, but it is associated with a Greek word for intoxicated (narcotic) and the myth of the children of that name who fell in love with his own representation. The English expression 'daffodil' is apparently produced from "asphodel", with which it was commonly compared.
The kinds are indigenous to meadows and woods in southern European countries and North Africa with a middle of variety in the Traditional western Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were created into the ASIA 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, nematodes and mites. Some Narcissus species have grown to be extinct, while others are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the initial times, but became ever more popular in Europe after the 16th hundred years and by the later 19th century were an important commercial crop centred mostly on holland. Today narcissi are popular as slice plants so that as ornamental plants in private and general public gardens. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering an array of colours and shapes. Like other members of these family, narcissi produce a true 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 use in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in literature and fine art, narcissi are associated with a true 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 rose of Wales and the sign of tumors charities in many countries. The appearance of the outdoors flowers in springtime is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to an underground storage light bulb. They regrow in the following 12 months from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm depending on the species. Dwarf varieties such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may expand as high as 80 cm.
The crops are scapose, having an individual central leafless hollow bloom stem (scape). Several blue-green or green, narrow, strap-shaped leaves come up from the light. The vegetable stem bears a solitary flower, but occasionally a cluster of bouquets (umbel). The blossoms, that are usually conspicuous and white or yellowish, both or rarely renewable sometimes, 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 bouquets may hang up down (pendent), or be erect. You can find six pollen bearing stamens encircling a central style. The ovary is inferior (below the floral parts) consisting of three chambers (trilocular). The fruits includes a dried out capsule that splits (dehisces) launching numerous black seed products.
The bulb lays dormant following the leaves and blossom stem die back again and has contractile origins that take it down further into the soil. The blossom stem and leaves form in the light bulb, 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 autumn flowering.
