Karen Midden, a professor in SIUC's Plant, Soil, and Agricultural Systems department, shows professor and horticulturist John Preece how to create a different kind of water garden: the "pond-less" waterfall. Instead of a pond at its base, this unique water garden features a small plastic reservoir that recycles the water back through the fall. Rocks and plants, such as irises, columbines, and hens and chicks, enhance this soothing backyard feature.
