Skip the orange ditch lilies. They are invasive and once established, they are impossible to eradicate. There are so much better daylilies. Astilbes and epimediums are a natural for an area like that and they go well with hostas.

Thanks for the suggestions oldroser. I will definatley include those! Any thoughts on a vine for my fence?

For a shade tolerant vine, you could try akebia quinata. It's perfectly hardy in zone 5 and fast growing. I have been told that it travels a bit, though I did not have that problem with mine. Mine was, however, bordered on two sides by asphalt. Akebia has unflashy flowers and only sets fruit if pollinated by an unrelated plant. You could also try a climbing hydrangea, but these take several years to establish and so require some patience. Tiarella and phlox divaricata make nice groundcovers under trees. Mertensia would do well there, too, as would dicentra, though these go dormant in summer.

For shade under trees you might also consider false solomon seal (the variegated one is nice), arisaema, hellebores, mayapples (which I think are hardy in zone 5)or ferns. For some variety, have a look at eleutherococcus sieboldianus 'Variegata', a striking, variegated shrub (no flowers) that does well in dry shade. I had one in sone 5 and loved it.

Compost the orange ditch lilies!
