Most hydrangeas only need morning sunlight. There is one exception to this rule in that is the hydrangea paniculata. The panicle hydrangea or hydrangea paniculata can soak up Sun all day long. Of course, they do well in shaded regions just the same as any other hydrangeas so if you happen to have a garden that gets morning sunlight but afternoon shade, you can quite literally pick any variety of hydrangea.
The reason for this timing is at the morning sunlight is lighter, not nearly as harsh so it gives the plant the sunlight it needs to continue growing but without burning the leaves. The afternoon sun is much hotter and can cause damage to the plant.
