5Will it grow where I live?
Mashua 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. It also needs warm summers – in Central Europe that means wine-growing regions, cities or a sheltered south-facing wall.
