Endless Summer Hydrangea here and in photo below. I used aluminum sulfate to acidify the soil in an effort to turn the flowers blue. Some look more lavender that blue, though. That means the soil is not quite acidic enough.
This spring two bluebirds checked out this birdhouse. It didn't meet their specifications, and they moved on. (Click on photo to enlarge)
A friend built me a bluebird house, so I'm ready to host them next year! Thanks, Denny!!!
