How the Rain Garden Works
Strategically located to intercept and collect the water runoff, the garden reduces erosion and sediment load as the water filters gradually through layers of gravel and soil and is cleansed. The rain garden mimics natural hydrological processes found in native woods and grasslands. Native plantings, which are well-suited to the climate and resistant to many endemic pests and diseases, have been selected for their ability to absorb and filter water.
Because of an under drain pipe which runs the length of the garden, Marymount is using herbaceous plants and low shrubs with relatively small to moderate root systems that will not aggressively spread and will provide year-round color, as well as wildlife habitat.
