Tiarella 'Sugar and Spice' makes a nice clump
Bleeding hearts (I'd suggest the ones with gold foliage because they look pretty good the whole season)
This picture has Astilbe, Bleeding Hearts, NOID blue grass and heuchera
This picture has Brunnera, All Gold shade grass and Sweet William that does well in the shade
Too pretty today to be inside playing on the computer, so I'll see if I can send some more suggestions later!
