Gardenality.com's Answer · Hi Linda,
Not sure I can provide you with a long list for a unique situation such as you have in Zone 5 with the shade and boggy soil, and with plants that don't spread too much, but here's a few suggestions to add to your list.
Carex - Sedge
Acorus - Sweet Flag
Clethra barbinervis
Red Twig Dogwood
Fothergilla 'Mt Airy'
Glossy-leaved Aster
Turn Of The Century Hibiscus
Inkberry Holly
Turkscap Lily
Cloud Nine Switchgrass
Pollia japonica
Umbrella Plant - Darmera peltata
Solomon's Seal - Polygonatum
Juncus 'Big Twister'
Mazus reptans - Does spread but great groundcover for shade in boggy soils
Bellium minutum
Green and Gold - Chrysogonum
Okay, so a fairly long list. I'm sure there's more but these are all I can think of and know about.
Hope this list is helpful and let us know if you have any other questions.
