Mine survived the heat of day when the nights were at least chilly- not something we see this far south. Humidity levels were horrid as well especially at ground level- have been toying with the idea of trying it in a raised bed above the dewpoints, and in an area with a lot more shade...when I get that bed put in. Never had it get large, but it was pretty til I had to leave out on the road and the neglect got it.
When I plant companion plants I am more after the ones that make the deer hesitate...french marigolds, peppermint, basils, onions/garlic... I have learned that the french marigolds emit a limonene (if memory serves) that deer don't care for. Since deer don't like to wade thru stinky stuff for their food I am hoping it is at least a deterrent...
