It may be a BB where reduced sunlight in some branches may have affected the way the leaves look.

Thanks Luis, the leaves on my BB are long and narrow these are more fuller, also it's coming in pink where everything in the area is blue ....the white on the leave in the picture(there is no white on the leave)... but I believe it's BB

Oh wow. I have a BB that had few flowers and this year it too bloomed pink and blue in my mostly alkaline soil. It is reblooming now again (just one bloom though).

The leaves do not seem to match well for H. macrophylla (or serrata). They look more like H. paniculata foliage.

Thanks gardengal, when I first noticed I thought it was Inv sp1 ... but how did it get under the deck when

Do you think you may have originally gotten two plants at one time and now you noticed the blooms? I have also had some macs spread by seed here too.

The ES is about 12/13yrs and the BB is 20+ yrs.....Inv Sp1 is a good 20+ ft away...this is the first time I noticed something different

There is very little doubt of its being a hydrangea.....that's pretty much a given :) But a seedling of either arborescens or paniculata would be my guess. Not a mac nor a serrata.

Ok I believe what I have is a wild Annabelle...picture taken just now...but how it got there is another story
