A downward rain garden, also known as a depression rain garden, is a type of landscape feature designed to capture and absorb stormwater runoff. These gardens are excavated into the ground, creating a depression that collects water. They are planted with native vegetation that can tolerate saturated soil conditions, and are effective in reducing stormwater runoff, filtering pollutants, and recharging groundwater. Pictures of downward rain gardens typically show these features with various plants and soil types, showcasing their natural and sustainable design.
