Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common names including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are being used to describe all or some members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by way of a cup- or trumpet-shaped corona. The blossoms are generally white or yellowish (orange or green in garden varieties), with either even or contrasting colored corona and tepals.
Narcissus were popular in traditional civilisation, both and botanically medicinally, but formally detailed by Linnaeus in his Types Plantarum (1753). The genus is generally considered to have about ten portions with about 50 species. The true quantity of kinds has mixed, depending about how they are categorized, 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 regions of southwest Europe. The exact origin of the name Narcissus is unfamiliar, but it is linked to a Greek term for intoxicated (narcotic) and the misconception of the young ones of this name who fell deeply in love with his own reflection. The English term 'daffodil' appears to be derived from "asphodel", with which it was compared commonly.
The species are native to meadows and woods in southern European countries and North Africa with a center of variety in the European Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were introduced in to the Far East prior to 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, 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 initial times, but became ever more popular in Europe following the 16th hundred years and by the late 19th hundred years were an important commercial crop centred primarily on holland. Today narcissi are popular as slash blooms so that ornamental vegetation in private and general public gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering an array of colours and shapes. Like other members with their family, narcissi create a 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 used in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in literature and skill, narcissi are associated with a number of themes in several cultures, ranging from fatality to fortune, and as icons of spring. The daffodil is the national bloom of Wales and the symbol of cancers charities in many countries. The looks of the wild flowers in planting season is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to an underground storage light. They regrow in the following yr from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm depending on the species. Dwarf types such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might increase as large as 80 cm.
The vegetation are scapose, having an individual central leafless hollow bloom stem (scape). Several green or blue-green, small, strap-shaped leaves arise from the bulb. The seed stem bears a solitary blossom, but once in a while a cluster of blossoms (umbel). The bouquets, 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 external ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The blossoms may hang down (pendent), or be erect. You will discover six pollen bearing stamens encircling a central style. The ovary is second-rate (below the floral parts) consisting of three chambers (trilocular). The berries includes a dried out capsule that splits (dehisces) releasing numerous black seeds.
The bulb lies dormant following the leaves and blossom stem die again and has contractile origins that take it down further in to the soil. The bloom stem and leaves form in the light bulb, to emerge the next season. Most kinds are dormant from warmer summer months to overdue winter, flowering in the spring and coil, though a few species are fall flowering.
