Hydrangea ID needed

Could you id these Hydrangea species?
Thank You!

 

#1 Looks like H. aspera. #2 guessing another H. aspera .#3 and #4 H. macrophylla, maybe subspecies H. serrata

 

There is a Hydrangea aspera ssp villosa which is what #2 might be. #1 is definitely H. aspera.

 

Now being called Villosa Group in UK. The big sterile flowers on the bigleaf hydrangea might indicate it's one of the recently circulated Teller cultivars, especially if a comparatively young specimen.
