I have total shade on the west side of the front porch. It's a covered front porch to begin with, but then the 60 year Magnolia tree is about 10' out from the porch, so even though it faces west, it's zero sun. Regular impatiens are the only thing that does well there. New Guineas and SunPatiens might live, but they pretty much stop blooming.
There's 2 hanging planters and 2 30" long planters on the railings, plus 2 on either side of the stairs that you can't see in this photo, but this is the solid pink I've planted last 2 years when I can't find Cherry Splash (this is Xtreme Pink). I also have 1 14" planter in a corner that I use just for testing what might survive there, never any good results though.
