Funnily enough, just as I was writing up the results of this year's successful sweetcorn endeavours I was leafing through the 1849 volume of the Illustrated London News (as you do) and came across some discourse about maize corn in England. The growing of any kind of maize (let alone sweetcorn) in the UK was still a pretty novel idea at the time, with only a handful of people having experimented with it, mostly with a view to using it as cattle fodder or as a cheaper alternative to other grains. The general opinion at the time was that the UK climate was too cold for maize and it would fail to ripen.
In September 1849 the ILN reported that an experimental hybrid maize crop was being grown in St James' Park in London, to establish whether this crop really was possible to cultivate in England. The trial site was an unfavourable spot surrounded by trees and shrubs "in the heart of the metropolis" and no manure had been used. Two other varieties were also trialled with it, an American maize and one from 'The Barbadoes'.
The immediate result of the trial was a disagreement among the ILN's readers:
As it turned out, the experimental maize thrived. The 'Barbadoes' and American corns apparently failed to reach maturity, but the "hybrid maize" (pictured above) did well:
"On Wednesday, the Maize introduced into this country from the Pyrenees, and sown as an experiment in St. James's Park, by Mr Keene, was harvested. It has fully succeeded. The grain is perfectly formed, full and ripe: the cobs are much finer than those grown on the Continent; a result – peculiarly gratifying in a public point of view – of very high importance; because it sets at rest the doubts which, in the first instance, were entertained in some quarters, that the soil and climate of this country were not capable of the product."
