Last year many of my plants 'fried' in the Spring heat. This year the cool temps and clouds are something the many hostas are enjoying, but I am not seeing any budding on the daylilies. I must say that everything is very green.
I have been taking daily pictures of my oldest peony plant. I looked back at pictures from 2010 and saw that it was blooming on May 17. Last year they withered in the heat, too. This year it just started to open on June 3. Here is one bloom from start to finish - the torrential rains last night took care of what was left.
