There are different types of shade. If your shady corner is open to the sky it gets more light, even with the roof overhang, than if a tree also shades the area. Between the spring and fall equinoxes, an open, northeast-facing area will get some morning sun. This is important because even shade plants do better with some light. If this area is densely shaded, your best choice would be ferns.

Summersweet (Clethra alternifolia) prefers sun to part shade but will grow in full shade, or morning sun with afternoon shade. Summersweet can also be a large shrub so plant it about 3 ft away from walkways, walls and such. This shrub prefers moist to wet soil. It is useful for stabilizing stream banks and widens by suckers. Its late awakening can be exacerbated by location. A shady spot can remain cool longer tricking the plant into thinking it's still early.

It's at the northern edge of its range, but the yew (Taxus x media, var. Densiformis) is an evergreen that does well in shade. Its mature height is around 3 ft, but its width is 5 ft. The plant is poisonous, so don't put it where small children or pets can get to it. I'm suggesting this plant for the following reasons: it takes shade; it is long-lived and slow growing but can be cut back if needed; it's not particular about soil type or pH, though it won't take wet soil: it has bright red berries in the fall.
