Japanese yellow sage (Salvia koyamae) Genus:  Salvia At first glance, this Japanese woodland native does not look as if it belongs in a shade garden, but
I find its spreading foliage and light-colored flowers do wonderfully as a small ground cover in dry-shade areas. Creamy yellow flower spikes sporadically appear from summer to fall, but hand-size, hairy green leaves are another attraction of this plant. It contrasts well with so many other fine-textured shade perennials that the flowers can be considered just a bonus. Japanese yellow sage is not choosy about soil pH or type. The spreading stems root as they touch the ground, eventually forming large, wide clumps. You can easily transplant any piece of rooted stem to fill gaps in your shade garden. -Jimmy Turner, Perennials for dry shade, Fine Gardening issue #133 Propagation:  Simply transplant any piece of rooted stem.
