ALL cultivars of Hydrangea macrophylla (mopheads and lacecaps) and Hydrangea arborescens (smooth hydrangea) will be happy with those light conditions. They are by nature shade lovers. While best if the conditions are flipped - morning sun with afternoon shade - they are moderately adaptable with necessary irrigation and dappled shade all day is fine as well. It is just full or heavy shade all day that will limit the flowering potential and too much sun will stress them out.

When I lived in Atlanta, mopheads did not like direct afternoon sun during the summer months. To try them in such a location though, consider keeping them in the pots and placing the pot in such a location thru summer-fall 2023. If the location works, plant them in the fall 2023; otherwise, immediately move the pot to a different morning sun only location and plant it there in the fall. Oakleaf hydrangeas bloom well here in Texas with full but bright shade all day. Do not forget to water them in the pot, especially after mid May and during dry winters. Consider bringing the pot into the garage during the winter or during the winter stormy time around February. I kept a few in ATL outside until the cold zapped the leaves.

Thank you!
