I have one area on the east side of my house, behind a tree and under very deep eaves, that gets virtually no sun. I have tried several shrubs and plants there with no success so far. My latest experiment is bugbane (cimicifuga simplex atropurpurea) and it seems to be doing quite well. It isn't a shrub, but it gets to be pretty good size, it blooms, and the blooms are fragrant. And I think the dark tinged foliage is very pretty.
