Will it grow where I live?

Silk tree is hardy to zone 7: lowlands, river valleys and cities across Central Europe are fine, harsher continental or upland sites need winter protection or a container. It also needs warm summers – in Central Europe that means wine-growing regions, cities or a sheltered south-facing wall.
