Yes, the big blue flowers are Hydrangea. They were here when I moved here, I love it. I posted other picks of it with the cats. Other plants are coneflowers, white hydrangea (I just planted this spring), yarrow, mountain mint, nine bark, herbs, including cat mint, hosta,butterfly bush, Joe pyeweed, and a ton of other stuff. I pretty much started with a clean slate in the center of the yard. When I first started with two parallel beds, it looked like two graves. I had to add the other two beds so people didn't think I was hiding bodies. It has been a work in progress for ten years this October.
