I live in zone 5, Southern Finland. My French tarragon stays out all winter, even at -25C. I don't cover it with anything and it's one of the first plants up every Spring. There's no reason to coddle it. It doesn't need fertilizer. I barely water it. It's about as independent a herb as you could ever hope for.
