Catherine, Thank you. I have tried them all. Even Buck. Our winters are strange. Some people think that a zone 6 is higher than a zone 5 but for some plants we may as well be a zone 2. I explained on another forum that our winters are not plant friendly for many plants. When you get extreme flooding rains for a few weeks and suddenly get freezing rain followed by snow. That may last a few weeks before you get Spring temps for a few weeks then repeat the rain, freezing rain, snow.
That many freeze thaw, water logged with plants in frozen blocks ice of many plants especially roses and Heucheras just cannot survive that type of weather. If we luck out and get winter and keep winter things survive but if we get our normal winter "Forget bout IT"
