State fruit of Kentucky, R. alleghenienis is hardy zones 3b through at least 9b, and likely warmer. The information in plant files is incorrect.

We live on Vancouver Island and have this plant along our property line. This year quite a number of the canes have large gauls on them. We would like to know if anyone knows what would cause this problem. We have cut the diseased canes off at ground level and burned them. Please advise.

Beside trailing blackberry, this may be the only other blackberry species to be hardy to Minnesota. It is rated at zone 4 hardy but many cultivars are made only for zone 5 - I have seen a few zone 4 cultivars online but hadn't purchased them - the only area I have seen them growing in the wild so far (they can be a bit difficult to tell from raspberries) is the St. Croix valley at O' Brien State Park. It prefers acidic soil, which explains its absent from most of Minnesota - the northern part of the the state is mostly acidic soil but too cold for it to grow while the southern part is mostly alkaline - hositle environment toward it. Maybe the St. Croix River brings acidic soil from further north making it more friendly toward highbush raspberry. It is also possibly zone 3b hardy but I will have to research further. It is introduced and spread in the wild in California and British Columbia. Minnesota is its western most range - generally limited by the Eastern Forest.
