The Japanese species Hydrangea sikokiana offers lobed foliage not unlike our native H. quercifolia, but problematically has a nearly sepal-less inflorescence the color of dust.  We’re still playing the numbers game with this combo, but this is an interesting intermediate, with lobed, purple saturated foliage and flowers in pale salmon with more sepals than the usual sikokiana infloresence.  In addition to referencing the color, the name is as a geographic tag and friendly taunt to one inspirational Hydrangea fancier in the Pacific Northwest.  You know who you are!
