I have tried two cultivars of this plant, and both have lost both after a couple winters. When researching, the range seems to be Zone 2 to 8b, so instead of it being not hardy enough, there must be another reason I am losing them. The ones I've tried are Azure Fairy and Prosperity. Perhaps our winters are too wet? Or they want a good hard freeze? Any ideas? Or fleabanes that work for you? I like to have these in the repellent section of my herb garden, such a nice little daisy. Thanks.
