Another thought would be a collection of native ferns (deer, lady, or wood ferns are less robust than sword fern) with some piggy-back, trillium, bleeding heart, and wild ginger interspersed.
Also, if you open some of the above plants in the database, there are some lovely multi-plant photos associated with them that illustrate some great placements done by others. Good luck!
I want to live in a world where the chicken can cross the road without its motives being questioned.
