Penstemon digitalis or Smooth Beardtongue as it is commonly called has been in my garden for three years now. The white blooms have just a hint of purple in the throat. It’s a hummingbird magnet in the shade garden. The basal foliage is evergreen which makes finding it a piece of cake in spring. It’s suppose to be a prolific reseeder but I haven’t had that happen in my garden yet.
Another white blooming native is Dicentra eximia ‘Alba’ or the Fernleaf Bleeding Heart. It is a more prolific bloomer than the cultivar Dicentra spectabilis, and is much smaller in size. Mine is combined with Brunnera ‘Jack Frost’ in the shade garden. The silvery white mottling compliments the white heart shaped blooms.
