That's a beautiful landscape to use as a basis for your own.
Even though you've answered your own question, you should know that the nursery has used the wrong genus and species name for your plant. Pratia no longer exists as a genus. The Pratia species have been reclassified as species of Lobelia. Pratia puberula is now a synonym for Lobelia benthamii, but I think your plant (Kelsey Blue) actually used to be classified as Pratia pedunculata, which is now a synonym for Lobelia pedunculata. I can't see the name Garden of Aaron is using because your link doesn't work for me.
If you're looking for other plants that thrive in the shade, especially dry shade, you might want to consider Epimediums.
