I have two NE facing borders in my garden due to the house and some very large shrubs which each cast their obliging shade. But I don't mind this location.
Near the house I have Fatsia japonica (which I know is bigger than you want) and together both areas have hostas, Alchemilla Mollis, Crocosmia, Acanthus, Euonymus, Skimmia, Geraniums, Hebes, Aquilegia, Heuchera, Astilbe, Ferns, Foxgloves (biennial and perennial) Lonicera nitida, Clematis (with their heads in the sun) and that's not including things I don't have but want such as Brunnera Jack Frost.
There are also some plants I have found to grow in these locations with only a foot or two more of sunlight such as Euphorbias and some Spiraeas.
