    My all-time favorite plant for shade or dappled shade. Mixes well with lungwort, bluebells, heuchera, smaller hostas, columbine, and lamium. The tiny little flowers that rise above the leaves are lovely, but I grow it primarily for its foliage.
  • Posted by Bonehead (Planet Earth - Zone 8b) on Mar 13, 2014 12:30 PM concerning plant:
    Grows quickly to a nice sized mound. Easy to divide. Brightens up any shady corner.

    A prolific bloomer and always looks wonderful!
  • Posted by Marilyn (Kentucky - Zone 6a) on Jan 15, 2012 3:11 AM concerning plant:
