Hardy geranium macrorhizum for the aromatic foliage which colours to red in winter and flowers in late spring. Geranium phaeum is another good one for shade. Cut back after the flowers in spring to get fresh new foliage with dark purple splodges.
Some varieties of phlox flower in late summer/early autumn and in dappled shade.
Pulmonaria and brunnera are good foliage plants for shade as long as you beef up the soil with some garden compost. They'll flower in spring and then you can cut them back to encourage fresh new foliage for the rest of the season.
There's a variegated, spotty persicaria virginiana that needs shade rather than sun. I like the Painter's Palette best.
Epimediums like shade and have gorgeous foliage plus spring flowers.
Snowdrops for winter and one or two narcissi like shade.
Alchemilla mollis - but cut off the flowers to stop it self seeding with gay abandon.
Quite a few grasses such as carex Ice Dance.
