Last night's episode showed the people harvesting a field of sweetcorn. I always thought this wasn't hardy in the Uk until fairly recently. I think even then it was only grown for animal fodder. Anyone know?
It was definitely grown here in East Anglia (for human consumption) around 1960. (That's as far back as I can go!).
The 'history' section here suggests that it only really became popular here in the UK after WWII (perhaps due to the large number of US servicemen in the country?) but it also indicates that the crop was in Europe by the 15th century:

I can recall my Dad growing it in the late 50's, although it never amounted to much, being a bit stunted and unappetising, so he went back to growing spuds.
