Ferns, black mondo grass, and the hakonecloa (Japanese forest grass) make great plantings at the base of rainchains - they'll thrive with the added moisture! And the river stones will help prevent muddy splashes - as well as (w/ some grade management) disburse any rainwater that might pool there... All this while enhancing the near-by patio! What a well-planned design!
Japanese Blood Grass - a warm-season ornamental grass that is selected for its attractive, red-tipped foliage. It grows well in U.S. Department of Agriculture plant hardiness zones 5 through 9 and thrives in sunshine and moist soil. I think I might have to give this one a try.
