I grow several different shade-loving phlox - stolonifera and divaricata - but they're all named varieties. You'd have to search for some native varieties. I do like the flowers in the spring but you might want more height in that area. While I like the stately Jack in the pulpits, they don't offer a lot of color until late summer with the seeds. I like bloodroot for early spring but don't know if that's a native for you. Are the wild geraniums native?
