You can keep Basjoo in the ground in Zone 5. I was Zone 4-5 in Ohio and my basjoo we never protected and melted to the corm and would come right back. Even grew a needle palm which set seed several times. I did build a little encloseure to cover it during very cold days. We had two days of warm spells and it nuked it. Single digit lows in winter was normal.
