Pink flowering bushes for shade.
Hello. The only plant I would recommend would be pieris japonica. And I offer that with great hesitation. Any flowering plant needs more than 3 hours of sunshine. There are varieties of this plant so I suggest you go to a nursery and look to see if any of them are attractive to you. You could also consider using coleus that is pink. It is an annual and needs to be replanted every year but it would give you all summer pink color.
