Culver's Root (Veronicastrum Virginicum) is an interesting plant. We grow it in shade along with some hostas and astilbes. It sends up these tall (6 feet!) spires of white flowers.
Next to and under the Culver's Root, we have Japanese Painted Fern. It is a delicate looking fern that is actually quite hardy and frows to a nice, decent size. It adds a lovely soft green color to the foliage around it.
These two plants are in one of my favorite corners of my garden.
