CORAL BELLS (Heuchera hybrids): Once you start collecting these shade loving plants you won't be able to stop. Exquisite leaf colors and airy spring or summer spikes of delicate white, pink, lilac, or scarlet flowers. Great in shade planters.
Campanula glomerata 'Superba' Amazing flower for cutting - so long lasting. And who doesn't love a purple centerpiece? Borderline xeric and tho this site notes it prefers well-draining soils, also takes clay just as well.
