Is the ground fairly moist shade?
My garden is north-facing and I have lots of damp shade! Things that do really well: fatsia, bamboo, viburnum tinus, variegated holly, primulas of all kinds (I like candelabra, denticulata), ferns, hellebores, box, acanthus, and all manner of spring bulbs.
More exotic options: erythronium (dogs tooth violent, so beautiful), tricyrtis formosana (toad lily), arums, brunnera, lamium, persicaria, ligularia, tiarella.
If it's really, really wet, you might even get some bog plants to work - lovely huge leaves!
