I have trouble growing calamint, which seems odd to me since it is so similar to other mints that grow easily. I think I've lost it again, despite our very mild winter. I've done some research and have found sources claiming it to be hardy in zones 4-7 or 5-9. I'm right smack in zone 8, either a or b. It apparently does not do well in hot humid summers, which is not really how I would describe my summer, but it has definitely gotten hotter in the last couple years. Has anyone else had luck with calamint and/or had troubles with it? I'm planning to replace it unless I can identify some reason why I should just pass on this plant.
