Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial vegetation 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 with a cup- or trumpet-shaped corona. The blooms are usually white or yellow (orange or red in garden kinds), with either standard or contrasting coloured tepals and corona.
Narcissus were well known in ancient civilisation, both medicinally and botanically, but formally identified by Linnaeus in his Species Plantarum (1753). The genus is generally thought to have about ten portions with around 50 species. The number of species has assorted, depending on how they are grouped, thanks to similarity between hybridization and varieties. 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 true name Narcissus is unidentified, but it is linked to a Greek word for intoxicated (narcotic) and the misconception of the children of that name who fell in love with his own representation. The English word 'daffodil' appears to be produced from "asphodel", with which it was commonly compared.
The varieties are indigenous to meadows and woods in southern European countries and North Africa with a center of variety in the Traditional western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild 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, 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 after the 16th hundred years and by the past due 19th century were an important commercial crop centred primarily on the Netherlands. Narcissi are popular as trim blooms and as ornamental crops in private and public gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a wide range of shapes and colours. Like other members of their family, narcissi create 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 led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in skill and books, narcissi are associated with a number of themes in various cultures, ranging from loss of life to fortune, and as icons of planting season. The daffodil is the nationwide flower of Wales and the icon of tumor charities in many countries. The looks of the outrageous 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 the underground storage light. They regrow in the next year from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm depending on species. Dwarf kinds such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may increase as tall as 80 cm.
The crops are scapose, having an individual central leafless hollow bloom stem (scape). Several green or blue-green, small, strap-shaped leaves arise from the light bulb. The vegetable stem usually bears a solitary blossom, but occasionally a cluster of bouquets (umbel). The plants, which can be usually conspicuous and white or yellowish, both or seldom inexperienced sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an exterior ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical designed corona. The plants may suspend down (pendent), or be erect. You will discover six pollen bearing stamens encircling a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The fruits includes a dry out capsule that splits (dehisces) releasing numerous black seed products.
The bulb lays dormant after the leaves and flower 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 bulb, to emerge the following season. Most species are dormant from warmer summer months to late winter, flowering in the spring and coil, though a few types are autumn flowering.
