So far there aren't any perennials that have died from juglone here, and we grow all of our hostas and shade perennials under and around black walnuts (we have over 60 of them here). I've killed some hydrangeas and a couple Physocarpus though.

Yes, the black walnut assault has begun in my gardens! So far they are the size of almonds, but over the season they will grow to the size of golf balls and small limes! I have to keep reminding myself that I am thankful for the shade. Nice list!

Some shrubs don't do well with black walnuts, hydrangeas and physocarpus as Chris pointed out; any kind of roses, azaleas, weigelia, spireas, lespedsia, are all things I've tried a time or two and didn't succeed. I tried Madonna lilies three times before I gave up, they just got weaker each year and finally stopped coming up.

But hibiscus, cimicifuga, garlic, thyme, artemesia, lavender, dianthus, passionflower, Dutchman's pipe vine, columbines, ruellia, creeping veronica, lamiums, can all be added to the list of things that will grow under them or within range of their roots.. Most native wildfiowers; trilliums, dog-tooth violets, mayapples, false solomon's seal, woodland phlox, Dutchman's breeches, wild strawberries (but not garden strawberries), ginseng, colt's foot, toothwort, other spring ephemerals, are all good.
