Sounds like Hydrangea macrophylla Lady In Red; see the link below.

Here is a link that might be useful: Hydrangea LIR

Could be Endless Summer Twist 'n Shout as well, which is very red-tinged (it's a hybrid of LIR and Penny Mac)...

I have one with red stems and green leafs called "Oregon Pride" by the nursery that sold it to me. Al

Oh, yes. I remember that one now. It is a sport of Merrit Supreme, no? How do you like it, Al?

I have all three-the lacecaps both ts and lir are monsters and have gotten large-Op is also very nice but not as big a plant

Very interesting observation. All three are advertised as up to 5' (height and width) but ts and lir were actually described as between 3' and 5' wide and tall!

What size have they gotten to in your garden?

Oregon Pride was purchased from Joy Creek, an Oregon nursery. Of the three Hydrangea from Joy Creek, this is the strongest grower. It is in a 14 inch container of gritty mix in its second year. I plan on planting it in the garden in the fall. AL

lir is 5 and ahalf by 5 and 5 years old but in a great spot as a es nearby is 6 by 5. TS is 2 years old and 4 by 4 already while op is 3 years ols and 4 by 2
