Pure...

We have an Oakleaf hydrangea in our garden. The detail in the flowers is lovely, white with hints of green. My only regret is that I would like to see more bracts of flowers on it. I’m wondering if the spot in which it is growing is a little too shady. But I do appreciate the existing bracts that are showing off their beauty. And I am wondering if “bracts” is the correct term of the clusters of flowers on the plant. Perhaps one of my knowledgeable gardening friends can put me right!
