Mme. Emilewold Mouillere, Blushing Bride, Queen of Pearls, Green Cloud, Green Shadow. White Swan.

I would skip the paniculatas (they don't bloom well in shade) but I would not exclude the arborescens. They produce big, rounded flowerheads and blend the creamy white and green coloring better than the macs.

Thank you GardenGal. So many gorgeous options. And I want the 'Mme. Emilewold Mouillere' just so I can say the name when asked what it is :)

I will look into these for sure. And will take another look at incrediball. It can get windy here (especially today), do you think it would hold up to the wind?

I live a block off the beach so winds are a given in my area. Annabells and their ilk do fine here, as do all other hydrangeas. 😊

Amongst the whites: Mme. Emile Mouillere, Princess Juliana, Regula, Sister Theresa, The White Swan and Blushing Bride (not exactly completely white, can have some slivers of blue in the PNW). I would not plant paniculatas in that amount of shade. These smooth hydrangeas have green blooms for a while but they start color changing after a while and turn white, etc.: Invincibelle Limetta or Invincibelle Sublime.
