Pruning hydrangea

I cut back the lace cap plant next to the bay tree to buds on stems that flowered last year. It’s clear that flowers are forming on the stems that these buds are growing into this year. Is this old or new wood? Either way it looks very promising, but I could have cut a bit lower to make a more compact shape.

The white mophead is also showing flowers coming on similar stems. This has had fewer, bigger flowers the last two years.
