Daylily or Hemerocallis provide lots f cover for wildlife ,, My wild frogs and Toads are always digging around them
The Snapdragons the Buckeye Butterflies love them , years they host here
only that their poison to everything else
I don't have many if any dwarf plants ,,a few ,,
One i have or had is a dwarf rose Yarrow , interesting plant , After bloom the seeds provide some interest , Kind of bland like though
