This is my favorite time of year in the garden. I don’t grow any roses that are suitable for cutting. But my hydrangeas are, obviously, and I usually have some in bloom from about July 4 until–if I am lucky– early October.
What I particularly like is the way that the blooms change color over the season–and this is true no matter what varieties I am growing.
The arborescens, or Annabelle, type, with their big white (or I do have pink varieties as well) will soften from white to lime–much like a PeeGee will.
The pink arborescens fade to a buff color.
And of course, the blues change to muted mauve (but this will happen later in the season for me so no photos yet). Very nice.
I have different varieties coming along as well too. So much to look forward to!

Hydrangeas were so much simpler years ago, when they were pink, blue or white, with not much in between. In our alkaline soil, there were only two, pink or white. In acidic soil, there were only blue and white.
Well, yes and no. I agree that they were simpler, sure. But here in Connecticut, until the rebloomers, and the different colored arborecens and PeeGee types, I was famous for saying that if I had a nickle for every “why isn’t my hydrangea blooming” question, I could have retired a very wealthy woman in a very short time! Sadly, we don’t have your wonderful climate. Even this year, I have some ‘Nikko Blue’ shrubs with no flowers.
