7Will it grow where I live?
Andean walnut is only hardy to zone 8, so outdoors year-round it needs the mildest spots in Central Europe – wine-growing regions, the Rhine valley, coasts, Lake Constance, Ticino – or a container overwintered under cover. Most of the British Isles and the Pacific coast of North America qualify. The summer heat it needs to ripen is out of reach outdoors in Central Europe – greenhouse or conservatory.
