Someone was searching for "catnip is hardy down to degrees"
According to Dave's Garden, Catnip is hardy to USDA Zone 3, which gets as cold as -40 °F!
Yikes.
Now, the website does not specify whether it will die back a little in those extreme temperatures.
I think it is safe to say, however, that if catnip can handle Zone 3, the kind of cold we get in Zones 8 and 9 should be no problem.
Around here, I would worry more about heat and drainage, when considering where to put my catnip.
