Checkout the Oakleaf Hydrangea. They can do sun or shade. I got one right now that gets 3-4 hours of summer sun with no problem. Oakleaf Hydrangeas are good for two reasons. You get your typical hydrangea bloom in the summer but come fall the leaves change into beautiful fall colors, which are really noticeable when you plant them somewhere OTHER than near the woods like right in front of a house.
