We are having similar temps. Most of the brugs around here bloom best in early fall when it begins cooling down. It's really hot and humid here during July and Aug. They definitely grow well in the heat but many don't bloom well during that time.

Same #*%^$@! thing here in Colorado. We're making up for a dry winter, a warm windy March and April, by having clouds, rain, and knitted scarf weather. Yuk!

Central Florida is strange as well. Cool at night (60's) hot as hades during the day (90's).
