I have Cool Splash Diervilla in a spot that gets part shade and it is doing great! Do you have enough sun for a hydrangea? If so, try Jetstream Oakleaf. If it’s too shady, it probably won’t flower but the leaves are beautiful. The Electric Lights Double Pink and Red Azaleas will do well. Rainbow Sensation is a weigela that can do part shade. Other perennials to add to your mix – astilbe, variegated Solomon’s seal, ferns and helleborus.
Thanks for writing!
