Hi Sue, thanks for taking the time to reply! MOBOT is a primary resource for me also. I never know whenever I see remarks about "cool summer" or "hot summer" locations what category my zone 5B falls into! I figured since we are not south, we would be "cool summer" (at least relatively), but of course we are not cool up here in summer, especially this summer...a very hot one, plus a long draught. Thanks for giving me the affirmation on that little voice in my head, which suggests this plant needs to be moved.... and welcome any further thoughts!
