That is gorgeous! I have a “Limelight” hydrangea that is taking over a garden. It’s lovely, but the flowers are a very pale light green to white, which I really like, but yours is a firecracker.
They ARE really pretty, but not cheap. Retail is $24-$37 each, but I got them at near-wholesale or they wouldn’t be in my yard, LOL!
I’ve kind of outgrown the old-fashioned Annabelles, though they are beautiful in the right spot. :)
