I'm afraid I don't actually know what the climate is like there. So depending on how cold your winters get, it may or may not be fine. Where I live, we get some snow during the winter months, some nights below freezing, etc but its not excessivly cold. In these conditions, even though we don't have harsh winters, we have to cover our plants with mulch, and sometimes cold frames or mobile greenhouses. Others will plant them close to their house. its important that they not freeze because they will most likely not come back.
