| Given that it is wet, there are certain ferns that would probably do well such as cinnamon, interrupted, sensitive, ostrich. Of the others I have experience with: Jack-in the-pulpit - might be too wet. Arrow Arum might work as a substitute Astilbe - I think these don't mind it pretty wet Snakeroot - not sure. The one I know by this name is Black Cohosh (Cimicifuga racemosa), which I think of as being a more mesic species Lily of the Valley - might be too wet Bunchberry - If this is Cornus canadensis, it likes moist, acid soil. Doubt it would like it. Forget-me-nots - Probably Pitcher Plant - Likes it acidic. Doubt it would work Hostas - Wouldn't have thought it would like wet roots but I saw one growing by a stream in a ravine once. Some others that might do well include blue lobelia, cardinal flower, Oswego tea (Monarda didyma), marsh marigold, swamp azalea, gentians. That's all I can think of off the top of my head |
