Answer: I have grown kerria in shade and although it is thinner and a bit leggier and blooms a bit lighter than in sun, it will survive there. If you really like it you might try one or two and see how it does for you. You may need to run a wire along the wall to tuck it up behind if it reaches outward too far towards the light. Another possibility might be the climbing hydrangea, Hydrangea petiolaris. You could also consider shrubs such as Nandina domestica (graceful arch, will do fine in a narrow space) or Euonymus fortunei cultivars such as "Emerald Gaiety" which will mound at the base like a shrub but also climb and cling to the wall. Among perennials you might look into Cimicifuga. Your local professional nursery staff may have other suggestions based on a more detailed understanding of the planting site and your design goals. Good luck with your project!
