Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common brands 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 with a cup- or trumpet-shaped corona. The blooms are usually white or yellowish (orange or green in garden varieties), with either even or contrasting colored corona and tepals.
Narcissus were well known in historical civilisation, both medicinally and botanically, but formally defined by Linnaeus in his Varieties Plantarum (1753). The genus is generally considered to have about ten parts with about 50 species. The amount of species has assorted, depending how they are classified, thanks to similarity between hybridization and varieties. 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 source of the real name Narcissus is unidentified, but it is linked to a Greek phrase for intoxicated (narcotic) and the misconception of the children of that name who fell deeply in love with his own reflection. The English word 'daffodil' appears to be derived from "asphodel", with which it was likened commonly.
The species are indigenous to meadows and woods in southern Europe and North Africa with a middle of variety in the Western Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were introduced into the ASIA to the tenth hundred years prior. Narcissi tend to be long-lived bulbs, which propagate by division, but are insect-pollinated also. Known pests, diseases and disorders include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have grown to be extinct, while some are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe following the 16th century and by the overdue 19th century were an important commercial crop centred generally on the Netherlands. Narcissi are popular as slice blooms so that ornamental vegetation in private and general public gardens today. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are grouped 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 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 fine art and books, narcissi are associated with a true number of themes in several cultures, ranging from death to good fortune, and as icons of springtime. The daffodil is the nationwide rose of Wales and the mark of tumor charities in many countries. The appearance of the crazy flowers in spring is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering to a underground storage light. They regrow in the next 12 months from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm with respect to the species. Dwarf species such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may develop as extra tall as 80 cm.
The plants are scapose, having a single central leafless hollow rose stem (scape). Several green or blue-green, narrow, strap-shaped leaves come up from the bulb. The flower stem bears a solitary blossom, but sometimes a cluster of flowers (umbel). The plants, that happen to be conspicuous and white or yellow usually, both or rarely inexperienced sometimes, consist of 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 formed corona. The blooms may suspend down (pendent), or be erect. You will discover six pollen bearing stamens surrounding a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The berry consists of a dried capsule that splits (dehisces) liberating numerous black seeds.
The bulb sits dormant after the leaves and blossom stem die back again and has contractile origins that yank it down further in to the soil. The flower stem and leaves form in the bulb, to emerge the following season. Most kinds are dormant from summer season to overdue winter, flowering in the spring and coil, though a few varieties are fall flowering.
