Question: I see many articles about dealing with dry shade but that's not quite the problem I have. Can you tell me any plants that will grow in wet shade?
Answer: When you have a specific challenging conditions in your gardening site—such as wet shade—it helps to match those conditions up to a nearby natural area and investigate the plants that inhabit it. "Wet shade" can be akin to a swamp, riverbank, lake shore and other naturally damp areas. You might check with the local chapter of your state's native plant society to learn what plants thrive in such areas near you. Wildflower.org, the website of the Lady Bird Johnson Wildflower Center, can also be very helpful because its plant listings are quite specific about not just what state the plant comes from, but what kind of natural landscape it typically occurs in.
That said, here are a few plants generally successful in wet to damp shade:
Summersweet (Clethra alnifolia)
Shrubby dogwoods (Cornus spp.)
Virginia sweetspire (Itea virginica)
Elderberries (Sambucus spp.)
Chokeberry (Aronia arbutifolia)
Spicebush (Calycanthus spp.)
Serviceberry (Amelanchier spp.)
Bee balm (Monarda didyma)
Cardnial flower (Lobelia cardinalis)
Piqsqueak (Bergenia cordifolia)
Sedges (Carex spp.) and certain ornamental grasses
