FAQ
Question: 

Are black raspberries hardy in northern Iowa?

Answer: 

Red and purple raspberries are hardy throughout the state.  Black raspberries, however, often suffer severe winter damage in northern Iowa and can be reliably grown only in central and southern portions of the state.  ‘Black Hawk’ (an Iowa State University introduction) is the hardiest black raspberry cultivar.
