So....update!
I bought 3 Heucheras last year and tried them out. I listened to you guys and tried to choose cultivars that were the hybrids of the more heat tolerant strain. My garden place had 2 of those. I got a third that wasn't;t that type.
The third one ended up croaking. Just MELTED in the heat and humidity.But there 2....made it through Spring, summer, fall, and a night of 27F this winter.
