This is getting silly. In the UK, grapes are easy to grow, but not
easy to get a crop from, and do not ripen reliably anywhere in the

crop from everywhere, and it can be tricky to BOTH get a crop of
green beans AND ripen some for seed. Broad beans are easier still,
but even they can be tricky in some places, especially if you want
to ripen some for seed.

Balderdash!!!

On a comparative scale, I'd say Nick was spot on. Although our grapes
have reliably cropped year on year, but I think we're just quite lucky
with where we've put them. :-)
