Answer: Hydrangeas tend to get wilty when exposed to hot afternoon sunshine. Some are more sensitive than others. It's the plant's way of conserving moisture. When the sun goes down the plant perks up and by the following morning it looks just fine. The only cure for this behavior is to move the plant to a more protected area. It will flower well if given morning sun and shade from afternoon sunshine. I'd move the plant this fall or early next spring so that it will look nice all day!
