Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial crops 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 by a cup- or trumpet-shaped corona. The blooms are generally white or yellow (orange or red in garden types), with either uniform or contrasting coloured corona and tepals.
Narcissus were popular in traditional civilisation, both medicinally and botanically, but formally described by Linnaeus in his Varieties Plantarum (1753). The genus is generally considered to have about ten parts with about 50 species. The true amount of species has assorted, depending about how they are classified, due to similarity between hybridization and types. The genus arose time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact origins of the name Narcissus is mysterious, but it is often associated with a Greek expression for intoxicated (narcotic) and the myth of the youth of that name who fell in love with his own reflection. The English expression 'daffodil' appears to be derived from "asphodel", with which it was commonly compared.
The varieties are local to meadows and woods in southern European countries and North Africa with a center of variety in the Traditional western Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were introduced in to the Far East before the tenth century. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are also insect-pollinated. Known pests, disorders and diseases include viruses, fungi, the larvae of flies, nematodes and mites. 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 increasingly popular in Europe after the 16th hundred years and by the overdue 19th hundred years were an important commercial crop centred primarily on the Netherlands. Narcissi are popular as slash flowers so that ornamental vegetation in private and public gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering an array of colours and shapes. 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 utilization in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in literature and artwork, narcissi are associated with a number of themes in different cultures, ranging from death to good fortune, and as symbols of spring and coil. The daffodil is the national bloom of Wales and the image of tumors charities in many countries. The appearance of the outdoors flowers in spring and coil is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to a underground storage light. They regrow in the next year from brown-skinned ovoid bulbs 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 expand as high as 80 cm.
The plants are scapose, having a single central leafless hollow bloom stem (scape). Several blue-green or green, slim, strap-shaped leaves arise from the light. The herb stem bears a solitary rose, but once in a while a cluster of blossoms (umbel). The flowers, which can be conspicuous and white or yellowish usually, both or hardly ever 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 disk to conical formed corona. The flowers may hang up down (pendent), or be erect. You will discover six pollen bearing stamens bordering a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The berries involves a dried out capsule that splits (dehisces) launching numerous black seed products.
The bulb sits dormant following the leaves and blossom stem die back again and has contractile origins that move it down further in to the soil. The rose leaves and stem form in the light, to emerge the following season. Most species are dormant from summer to overdue winter, flowering in the springtime, though a few species are autumn flowering.
