Answer: Pittosporum Tobira will tolerate winter temperatures of about 28F. That puts it in the "borderline" category in your gardening region. I think it's worth the effort - you can provide temporary protection if there's a predicted prolonged cold snap. I've protected my plants by driving 4 stakes into the ground around the plant and attaching burlap, making an effective screen against cold winds. Hope this information helps you decide whether you're willing to take a chance with Tobira in your yard.
