Note that 'Preziosa' is a hybrid between H. macrophylla and H. serrata, making H. serrata 'Preziosa' a synonym of H. 'Preziosa'. Also that it produces mop-head type inflorescences consisting entirely of rose-pink ray florets that become reddish purple by fall. Whereas your picture here shows a white lace-cap type.

Oops, my error. the photo was in the file of the red stemmed hydrangeas. Might be Lady in Red.

The leaves and stems in your second and third shots are certainly quite similar.

They are looking beautiful! Love the variation of color in the leaves too.
