Calgary, Alberta, Canada - Zone 3
-30 C to +30 C (rarely!); elevation ~1130m; annual precipitation ~40 cm
I dunno--he does grow some pretty impressive stuff up there in zone 1--tons of species lilies, for example..he does have- long summer days, as you mention, -a fairly warm summer, at least in recent years, its often warmer than ours here next to the foothills! -deep persistent snow cover for those plants that may be partial to that!
