I was thinking hydrangea or viburnum.

Viburnum blooms in June/July and the flowers are smaller and shaped rather flat.
Limelight Hydrangeas are a fairly new breed blooming in late summer, Currently the rage of landscapers because they are so brilliant and the flowers last.

They remind me of Oak leaf Hydrangeas but are more profuse bloomers.

One gallon plants range from $15 to $25. Hardy in your area
