I have chocolate mint and I find its not as hardy as other varieties.
It does really well with fairly wet and shady conditions (I had it under my elevated rain barrels and it did great, but didn’t spread beyond that) and poorly otherwise (since moving the rain barrels and exposing it to constant sun, it doesn’t want to grow much at all, much less spread).
Idk how much that’ll help your quest, but perhaps it will :)













It’s still wild to me that many parts of the developed world simply don’t use screens on windows.
But from what I can tell its also mostly places where people don’t even have AC because it simply never gets that hot.
Must be nice. (I don’t have AC yet, but I’m an outlier in my area, and I hope to add it this year because a heat pump would be an absolute blessing even if I still need to use my gas furnace as backup)
