Bold glossy foliage of Podophyllum pleianthum is the real attention grabber in this scene.
Black mondo grass (Ophiopogon planiscapus 'Nigrescens'), goes with everything. Pair it with sliver, blue, yellow or green foliage in sun to shade — this is one flexible and tough grass!
Delicate gunmetal silver foliage of Japanese painted fern (Athyrium niponicum var. pictum) is a nice complement to the black mondo grass.
