Lyn, it is a sterile,agastache...thus a very long flowering variety. Heatwave.
Runny, that hydrangea was planted late winter. it is now over 120 cm tall with more to come. In future years it will be 200 cm with annual pruning. Those huge flowers will turn white. I love it.
I have another, Kyushu, which is slightly different but pure white right now and this is delightful.
