It is a Hydrangea paniculata but precisely which one is difficult to pin down. A good many of the older cultivars, like Tardiva, Pink Diamond and Unique sport those big, loose flowerheads. Regardless, looks like a robust and healthy plant!

Thanks gardengal! It is quite large and happy looking. Here's hoping I can keep it that way. :)

I saw a QuickFire at a garden center that look like that. At first I thought it was Pinky Winky, but no it's not.
