Answer: Hydrangeas will flower best if they get 4-6 hours of sunshine. They also tend to wilt in hot afternoon sunshine. So, the best spot in the garden would be one that gets direct morning sunshine and protection from hot afternoon sun. This can be full afternoon shade such as from a building or dense tree, or filtered afternnon shade such as under the canopy of a deciduous tree. Endless Summer hydrangeas will adapt to even less sunshine so the site you describe should be just fine. Enjoy your new hydrangeas!
