It is a hydrangea paniculata.. The panicle shaped blooms and heart shaped leaves help identify it.

Not sure which kind. If the pics are from today, I am surprised to see blooms that are starting to open.... although paniculatas in the northern half of the country, Canada and H. paniculata Tardiva, they all bloom late in the season.

When did you take the pics, Tracy? And where are you located?

Hello - I live in zone 5, Chicago. The pictures were taken this past week.

Here are links to several hydrangea nurseries that have many paniculata bloom pictures.

Wait until the blooms open some more and then compare them to the pictures in the links.
