The rosemary’s looking quite fresh and perky, buried tip deep in snow. There are many cultivars, some apparently able to overwinter in quite brutal cold. I have three types here, two without names (one a survivor of last winter’s rosemary greenhouse debacle), plus a new Barbecue cultivar. How hardy are they? Are they as happy as they look in the snow? Will I eventually take them in (as planned)? Or mulch them where they stand?
