Blueberries are a new world fruit (but then again so is the prickly pear that is so common in the Mediterranean), the European equivalent is the bilberry and AFAIK it only grows in mountainous areas at our latitudes. Blueberries are widely cultivated, but for example in Italy the largest production comes from Piedmont, which is usually classified as humid subtropical (almost no olive trees, but large grape productiont).
